The fact that you are using spark shouldn't hold you from using external python libraries. You can import sklearn library in your spark-python code, and use sklearn logistic regression model with the saved pkl file.

I have trained a logistic regression model in sklearn and saved the model to .pkl files. Is there a method of using this pkl file from within spark?

This is actually now solved - or rather, never actually broken; I was writing to a parent package variable (i.e. by creating the variable in the child package, configuring the task, setting delay validation to true and then deleting the variable) - it appears when I do this, it takes SSIS a long time to write to it! If i use a child package variable, it completes straight away but it takes 1-2 minutes for the parent package variable to be written to. At least it's completing.

I am using SSIS's Execute Process Task to execute a compiled python script. The script executes as expected and completes as expected with either success or failure. However, when I configure a variable to catch Standard Error or Standard Output, the application hangs. The command prompt flashes up and down indicating that the execution has completed but then the SSIS task itself never completes. To reiterate, when I don't configure the variable, there is no issue and the task finishes as expected. I have also debugged the execution of the script independently and I can verify that: Status code is 0 when success. Standard error contains text. Any ideas what is causing the task to hang?

I'm dealing some something similar right now. I want to make my epochs shorter so I can record more information about the loss or adjust my learning rate more often. Without diving into the code, I think the fact that .fit_generator works with the randomly augmented/shuffled data produced by the keras builtin ImageDataGenerator supports your suspicion that it doesn't reset the generator per epoch. So I believe you should be fine, as long as the model is exposed to your whole training set it shouldn't matter if some of it is trained in a separate epoch. If you're still worried you could try writing a generator that randomly samples your training set.

I'm using Keras with Theano to train a basic logistic regression model. Say I've got a training set of 1 million entries, it's too large for my system to use the standard model.fit() without blowing away memory. I decide to use a python generator function and fit my model using model.fit_generator(). My generator function returns batch sized chunks of the 1M training examples (they come from a DB table, so I only pull enough records at a time to satisfy each batch request, keeping memory usage in check). It's an endlessly looping generator, once it reaches the end of the 1 million, it loops and continues over the set There is a mandatory argument in fit_generator() to specify samples_per_epoch. The documentation indicates samples_per_epoch: integer, number of samples to process before going to the next epoch. I'm assuming the fit_generator() doesn't reset the generator each time an epoch runs, hence the need for a infinitely running generator. I typically set the samples_per_epoch to be the size of the training set the generator is looping over. However, if samples_per_epoch this is smaller than the size of the training set the generator is working from and the nb_epoch > 1: Will you get odd/adverse/unexpected training resulting as it seems the epochs will have differing sets training examples to fit to? If so, do you 'fastforward' you generator somehow?

In Keras, If samples_per_epoch is less than the 'end' of the generator when it (loops back on itself) will this negatively affect result?

Do something like this before running your main script export TF_MIN_GPU_MULTIPROCESSOR_COUNT=4 Note though that the default is set for a reason -- if you enable slower GPU by changing that variable, your program may run slower than it would without any GPU available, because TensorFlow will try to put run everything on that GPU

I get a message that says my GPU Device is ignored because its multiprocessor count is lower than the minimum set. However, it gives me the environment variable TF_MIN_GPU_MULTIPROCESSOR_COUNT but it doesn't seem to exist because I keep getting command not found. When I look at the environment variables using set or printenv and grep for the variable name, it doesn't exist. Does anyone know where I can find it or how I can change its set value?

In windows, create a new environmental variable with this name and assign its value. You can do that by right clicking on the This PC in File Explorer, select Properties at bottom, then select Advanced system settings on left. That will get you to the System Properties dialog. Also you can type "environmental properties" in Cortana Search. From there you click the Environmental Variables button. Once in the Environmental Variables dialog, select new to create the variable and assign the value, then back out. You may have to restart your IDE or open a new DOS window for that environmental variable to be visible.

Under OS X (10.11.6) I installed the current Python 3.5 version of Anaconda. Anaconda Navigator then works just fine to launch sypder, jupyter,or qtconsole with python 3.5.2 running. At the command line I also created a python 2.7 environment (conda create --name python2 python=2.7 anaconda). But now when I open Anaconda Navigator, go to Environments in the left pane, and select my python2 environment, still if I go back to Home and launch sypder, jupyter, qtconsole, the python version shown is still 3.5.2. I tried closing Anaconda Navigator, executing "source activate python2" at the command line, and reopening Anaconda Navigator, and again selecting python2 from Environments there. But still sypder, jupyter, qtconsole open with python 3.5.2. How do I launch with python 2.7?

How open python2.7 in spyder, jupyter, qtconsole. from Anaconda Navigator installed with python3? (OS X)

Just like everything else in a Docker Container, your libraries are inside the container. Unless you mount a host volume, or a volume from another container of course. On the plus side, though, they're copy-on-write, so if you're not making changes to the libraries in your container (why would you do that anyway?) then you can have 100 running containers from the same image and they don't require any extra disk space. Some people advocate for using a virtualenv within the container - there are pros and cons to the approach, and I don't think there's a one-sized-fits-all answer, though I would lean for not having a virtualenv.

In an environment where Docker Containers are used for each application, where are Python's shared libraries stored? Are they stored separately within each Docker Container, or shared by the host O/S? Additionally I'm wondering if it would be best practice to use a virtual environment regardless?

When using Docker Containers, where are shared Python libraries stored?

MRocklin's answer is correct and this answer gives more details on when it's appropriate to convert from a Dask DataFrame to and Pandas DataFrame (and how to predict when it'll cause problems). Each partition in a Dask DataFrame is a Pandas DataFrame. Running df.compute() will coalesce all the underlying partitions in the Dask DataFrame into a single Pandas DataFrame. That'll cause problems if the size of the Pandas DataFrame is bigger than the RAM on your machine. If df has 30 GB of data and your computer has 16 GB of RAM, then df.compute() will blow up with a memory error. If df only has 1 GB of data, then you'll be fine. You can run df.memory_usage(deep=True).sum() to compute the amount of memory that your DataFrame is using. This'll let you know if your DataFrame is sufficiently small to be coalesced into a single Pandas DataFrame. Repartioning changes the number of underlying partitions in a Dask DataFrame. df.repartition(1).partitions[0] is conceptually similar to df.compute(). Converting to a Pandas DataFrame is especially possible after performing a big filtering operation. If you filter a 100 billion row dataset down to 10 thousand rows, then you can probably just switch to the Pandas API.

Nano Server is designed to be administered remotely, the local 'console' only allows you to set firewall rules and network config. You'll need to do everything via a remote session with Nano Server. If that's not suitable for you the only option is to move to the full Server 2016 OS instead as this has the standard local console with GUI.

faced a similar problem (Python 3.4 32-bit, on Windows 7 64-bit). After installation of cx_freeze, three files appeared in c:\Python34\Scripts: cxfreeze cxfreeze-postinstall cxfreeze-quickstart These files have no file extensions, but appear to be Python scripts. When you run python.exe cxfreeze-postinstall from the command prompt, two batch files are being created in the Python scripts directory: cxfreeze.bat cxfreeze-quickstart.bat From that moment on, you should be able to run cx_freeze. cx_freeze was installed using the provided win32 installer (cx_Freeze-4.3.3.win32-py3.4.exe). Installing it using pip gave exactly the same result.

Ok, I am using python 3.4.3 and I think I downloaded the right file but when I go to python shell, it says No module named 'cx_Freeze' I know there are plenty of questions like this but none of them helped. There was one I found using my exact same problem and version but even that did not work. I do not know what to do. I have put the file in the same place, I think anyways, as python is and I tried putting it on my desktop but still does not work. Any ideas?

Ok, I figured it out. So this is for all the future people have the same problem as I am. First, download pip. Then open a python shell and import pip. This is to make sure the download of pip was successful. Then go to the cx_Freeze website and for python 3.4.3, it will be the last one I think. It will say the version of cx_Freeze and then say the version of python which is 3.4.3 for me. That will download and then go to python shell and import cx_Freeze. It should work. Remember that you have to capitalize the "F" and have the code be exactly like this "cx_Freeze" but without the quotes. That is how I solved this problem with this exact python version.

If I run two different Python scripts simultaneously, I see a console window which shows output from each of the scripts alternately, switching back and forth every second or so. If I open a second console window before running the second script, the same thing happens - both console windows switch between the 2 scripts. How can I get each script to output to its own console window?

Reasons could be any of the following: Either the python files (at least one) have lost the formatting. Python is prone to formatting errors At least one installation (python, Robo) doesn't have administrative privileges. Environment variables (PATH, CLASSPATH, PYTHON PATH) are not set fine. What does python --version print? If this throws errors, installation has issues.

This field is meant to be used in combination with an earlier timestamp field that is used as a reference for the upper 16 bits. The proper way to deal with this field is summarized as follows: mesgTimestamp += ( timestamp_16 - ( mesgTimestamp & 0xFFFF ) ) & 0xFFFF;* my problem is not to obtain the two timestamp but to combinate the two in python thanks

I have made a simple python script and built a 64-bit Windows executable from it via pyinstaller. However, most computers at my office run 32-bit Windows operating systems, thus my program does not work. From what I have read, it is possible to make an executable for 32-bit systems as long as I use the 32-bit version of python. So I went ahead and installed the 32-bit version of python 3.5, but I can't find the way to link pip to the 32-bit version of python so I can install all the necessary modules. Every time I call pip it displays all the modules that are installed on the 64-bit version, even though by default I am running the 32-bit version python.

I've used the following set up on my application: Task is initiated from Django - information is extracted from the model instance and passed to the task as a dictionary. NB - this will be more future proof as Celery 4 will default to JSON encoding Remote server runs task and creates a dictionary of results Remote server then calls an update task that is only listened for by a worker on the Django server. Django worker read results dictionary and updates model. The Django worker listens to a separate queue, those this isn't strictly necessary. Results backend isn't used - data needed is just passed to the task

Celery workers and rabbitmq running from another server. My initial issue being, how to do i access django models from the celery tasks resting on another server? and assuming I am not able to access the Django models, is there a way once the tasks gets completed, i can send a callback to the Django application passing values, so that i get to update the Django's database based on the values passed?

For deploy you only need to discard the loss layer, in your case the "EuclideanLoss" layer. The output of your net is the "bottom" you fed the loss layer. For "SoftmaxWithLoss" layer (and "SigmoidCrossEntropy") you need to replace the loss layer, since the loss layer includes an extra layer inside it (for computational reasons).

I have trained a regression network with caffe. I use "EuclideanLoss" layer in both the train and test phase. I have plotted these and the results look promising. Now I want to deploy the model and use it. I know that if SoftmaxLoss is used, the final layer must be Softmax in the deploy file. What should this be in the case of Euclidean loss?

In general, you would not need to pass the parameters for Task A to Task B, but Task B would then need to generate the values of those parameters for Task A. If Task B can not generate those parameters, you would have to setup Task B to take those parameters in from the command line, and then pass them through to the Task A constructor in the requires method.

So I have two tasks (let's say TaskA and TaskB). I want both tasks to run hourly, but TaskB requires TaskA. TaskB does not have any parameters, but TaskA has two parameters for the day and the hour. If I run TaskB on the command line, would I need to pass it arguments?

How do Luigi parameters work?

That's a nice idea, but wx' text boxes are either entirely read only, or editable. I think the way to go for it is to query your position inside the text box for each cursor movement, and toggle the text box state readonly/editable according to you current position, current selection, etc.. It looks like a tough task, though... :-)

I am trying to determine if something is possible. I haven't written any code for this specifically yet. Using wxPython I would like to set up a text box (possibly a staticText) with primarily un-editable text. However I need certain parts, individual words, to be editable similar to PDF document with added text boxes. The ultimate goal is to visually display an XML file and allow a user to directly edit only element text and nothing else in-situ. I have a couple of other ways of doing this but they are very much sub-optimal. Thanks for any input/direction/help.

No, not always. The server however usually packs multiple messages into containers. I would advise that you decode all the data returned from the server. You then have a full view /log of all that is being returned, then you can decide on what needs to be replied to.

I'd like to understand the sequence of events when sending a method to the telegram server. For example, if I send the get_future_salts method I am expecting from the server a response of type FutureSalts, but what I receive is a type of MessageContainer (which I'm having trouble parsing, but that is a separate issue). If I ignore the MessageContainer object and simply request the next response from the server I receive the expected FutureSalts object. Will there always be a MessageContainer object returned for each method called? If so, do I need to parse and process these MessageContainer objects?

Unfortunately I do not know of a way in nosetests to perform this action. I actually ended up uninstalling nosetests and using just coverage.py because it seems like nosetests and coverage don't play nicely together. I know for a fact you can specify down to individual test methods what you want to run. I'm not sure if that's exactly what you are looking for but I beat my head against a brick wall for days trying to get nosetests to cooperate with no luck. Maybe it would save some effort to switch and run coverage.py directly instead?

1

0

Is there a way to have nosetests restrict the coverage information to only the tests that were run? I know about the cover-package flag, but it would be nicer if you didn't have to specify the package. This would be especially useful when running a a single unit test class that lives in a file with multiple unit test classes.

This is going to sound different but I know the powershell command will get you the driver version. strCommand = r"powershell.exe ""Get-WmiObject Win32_PnPSignedDriver | select devicename, driverversion | ConvertTo-CSV""" Then you can parse each line in your output. Each line is csv delimited so you have the Driver Name, and the Driver Version. I wrote a quick demo but since I am still a bit new here my code did not look right. But that is my suggestion.

I'm thinking of something like python3 my_script.py --pythonpath /path/to/some/necessary/modules Is there something like this? I know (I think) that Pycharm temporarily modifies PYTHONPATH when you use it to execute scripts; how does Pycharm do it? Reasons I want to do this (you don't really need to read the following) The reason I want to do this is that I have some code that usually needs to run on my own machine (which is fine because I use Pycharm to run it) but sometimes needs to run on a remote server (on the commandline), and it doesn't work because the remote server doesn't have the PYTHONPATHs that Pycharm automatically temporarily adds. I don't want to export PYTHONPATH=[...] because it's a big hassle to change it often (and suppose it really does need to change often).

Provide temporary PYTHONPATH on the commandline?

Admission: I don't use PyQT, but I use Qt in C++. I believe it would work the same. The trick here, is to as you run QHBoxLayout::addWidget(), you define a stretch factor (greater than zero) to the widgets you want to stretch. You define a zero-stretch factor (the default) to the ones you want to stay small. Have you run QWidget::setMaximumWidth() on the smallish widgets? That would also be useful, perhaps.

Is there a way to set a fixed width of a QHBoxLayout? For example, when I have two small widgets in it that take up little space and I don't want the two to split over the entire screen width when I full screen the app. The widgets already have their widths set to their minimumSizeHint() widths.

I am facing a strange problem right now. I am using pypyodbc to insert data into a test database hosted by AWS. This database that I created was by hand and did not imitate all relations and whatnot between tables. All I did was create a table with the same columns and the same datatypes as the original (let's call it master) database. When I run my code and insert the data it works in the test environment. Then I change it over to the master database and the code runs all the way through but no data is actually inputted. Is there any chance that there are security protocols in place which prevent me from inputting data in through the Python script rather than through a normal SQL query? Is there something I am missing?

You can either go directly to the dictionary of where Pip is installed, like Scripts on Windows. From that hold down the left shift button and right-click on it.

F9 is the key that does the job for you. To replicate the RStudio style, go to Preferences in Tools menu and go to Keyboard Shortcuts. Since Ctrl + Enter is assigned to another function, change that first. Then assign the F9 key value to Ctrl + Enter. Now Spyder is the same as RStudio. Atleast in a way.

Coming from R studio I imagine you were hoping to have a command that runs the next command, rather than just that one row (which can break a command into several parts and cause errors). The exact equivalent doesn't exist yet but if you get accustomed to adding #%% before and after chunks ("cells") you want to run together then you can use the following commands to run the whole chunk. Run cell: Ctrl + Return Run cell and advance : Shift+Return

Error says: ImportError: No module named tweepy I am sure Tweepy is installed because, pip freeze | grep "tweepy" returns tweepy==3.5.0. I created another file x.py with just one line import tweepy in the /tmp folder and that runs without an error. Error occurs only on HDFS. Also, my default python is Python 2.7.12 which I installed using Anaconda. Can someone help me with this issue? The same code is running without any such errors on another cluster running on Centos 6.6. Is it an OS issue? Or do I have to look into the Cluster?

In most simple way, a virtual environment provides you a development environment independent of the host operating system. You can install and use necessary software in the /bin folder of the virtualenv, instead of using the software installed in the host machine. Python development generally depends of various libraries and dependencies. For eg. if you install latest version of pip using sudo pip install django, the django software of the specific version will be available system wide. Now, if you you need to use django of another version for a project, you can simply create a virtaulenv, install that version of django in it, and use, without bothering the django version installed in os. Yes, it is strongly recommended to setup separate virtualenv for each project. Once you are used to it, it will seem fairly trivial and highly useful for development, removing a lot of future headaches.

It allows you to switch between different dependencies and versions of Python and other systems like PIP and Django. It is similar to using Docker where you can pick and choose each version. It is definitely recommended. If you are starting fresh and using the latest versions, you do not NEED to use it however it is good practice to just install virtualenv and start using it before you install django.

A virtual environment is a way for you to have multiple versions of python on your machine without them clashing with each other, each version can be considered as a development environment and you can have different versions of python libraries and modules all isolated from one another Yes it's very important. For example without a virtualenv, if you're working on an open source project that uses django 1.5 but locally on your machine, you installed django 1.9 for other personal projects. It's almost impossible for you to contribute because you'll get a lot of errors due to the difference in django versions. If you decide to downgrade to django 1.5 then you can't work on your personal projects anymore because they depend on django 1.9. A virtualenv handles all this for you by enabling you to create seperate virtual (development) environments that aren't tied to each other and can be activated and deactivated easily when you're done. You can also have different versions of python You're not forced to but you should, it's as easy as: virtualenv newenv cd newenv source bin/activate # The current shell uses the virtual environment Moreover it's very important for testing, lets say you want to port a django web app from 1.5 to 1.9, you can easily do that by creating different virtualenv's and installing different versions of django. it's impossible to do this without uninstalling one version (except you want to mess with sys.path which isn't a good idea)

While I can't directly describe the experience with Django and virtual environments, I suspect its pretty similar to how I have been using Flask and virtualenv. Virtual environment does exactly what it says - where a environment is set up for you to develop your app (including your web app) that does not impact the libraries that you run on your machine. It creates a blank slate, so to speak, with just the core Python modules. You can use pip to install new modules and freeze it into a requirements.txt file so that any users (including yourself) can see which external libraries are needed. It has a lot of importance because of the ability to track external libraries. For instance, I program between two machines and I have a virtual environment set up for either machine. The requirements.txt file allows me to install only the libraries I need with the exact versions of those libraries. This guarantees that when I am ready to deploy on a production machine, I know what libraries that I need. This prevents any modules that I have installed outside of a virtual environment from impacting the program that I run within a virtual environment. Yes and no. I think it is good practice to use a virtual environment for those above reasons and keeps your projects clean. Not to mention, it is not difficult to set up a virtual environment and maintain it. If you're just running a small script to check on an algorithm or approach, you may not need a virtual environment. But I would still recommend doing so to keep your runtime environments clean and well managed.

I am very much new to the process of development of a web-application with django, and i came across this setting up and using virtual environment for python. So i landed with some basic questions. What does this virtual environment exactly mean. Does that has any sort of importance in the development of web-application using django and python modules. do i have to worry about setting up of virtual environment each time in the development process.

venv has the activate script which you can modify to add your environment variables. I would add the variables at the bottom, making a nice comment block to clearly separate the core functionality and my custom variables.

I'm using venv (used pyvenv to create the environment) and would like to set up environment variables here, but postactivate looks like a virtualenv thing. Can this be done with venv?

If you turn on the debug logging you should see how exactly is data transmitted. Or try netstat or Wireshark to see if it makes connection to port 443 rather than 80. From my experience with boto3 and S3 (not Lambda) it uses HTTPS, which I would consider somewhat secure. I hope the certificates are verified...

I am using the Python AWS API. I would like to invoke a lambda function from client code, but I have not been able to find documentation on whether the payload sent during invocation is encrypted. Can someone watching the network potentially snoop on the AWS invocation payload? Or is the payload transmitted over a secure channel?

Does Boto3 encrypt the payload during transmission when invoking a lambda function?

When a python program runs, the main script is always passed through the interpreter. When a module is imported, however, python checks its cache ( subdirectory named __pycache__) where it stores modules that have previously been compiled to bytecode. If the date of the cached copy matches the date of the source code date, it uses the cached version. That probably accounts for what you are seeing.

I have a scrip 'xyz.py' that I'm importing as a module for another script (Main.py). Everything in xyz.py is inside of a class that I call in Main.py. Both, xyz.py and Main.py share the same import statements: "xml.etree.ElementTree"; "Tkinter"; "cv2"; "tkFileDialog"; "tkfd"; "from PIL import Image"; "ImageTk"; "os" I noticed that when I run in Main.py the class having all the methods and statements of xyz.py, they run faster as a module than as the main script. Is there a general fact behind this observation that I could use to speed up other stuff? Thank you. PS: I didn't provide the code because it sums up to >400 lines, and I don't know exactly what I'm supposed to be looking at, so I'm not able to take a small and relevant sample.

why does a script run faster as a module?

I had the exact thing happen to me except on High Sierra. I had deleted the old version folders of Python in /System/Library/Frameworks/Python.framework/Versions/, which was a mistake seeing that these are the Apple installed Python files. After trying to launch Xcode, Xcode could no longer access the Python files it needed. Unfortunately I had deleted them and emptied the trash, so the only way I could restore those files was by reinstalling High Sierra. So if you run into this plugin error and you've messed with Python files, you need to recover those files either by taking them back out of the trash or by reinstalling your operating system (reinstalling doesn't erase the data on your computer, but it will add missing files, such as the Python ones I deleted). Hope that helps someone in a similar situation.

when launching Xcode beta 8 on a macOS Sierra beta I'm getting this error: Loading a plug-in failed. The plug-in or one of its prerequisite plug-ins may be missing or damaged and may need to be reinstalled. After searching, it seems that the issue is related with python and the new security measures that Apple introduced after XCode Ghost. I couldn't find a solution, anybody can help? EDIT By looking at the Xcode logs, I noticed that it has NOTHING (apparently) to do with Python. I see a whole bunch of *Requested but did not find extension point with identifier Xcode.** errors I have to say that I also have Xcode 7 installed on my machine.

I'm writing a code to read serial input. Once the serial input has been read, I have to add a time stamp below it and then the output from a certain software. To get the output from the software, I want python to write a certain command to the terminal, and then read the output that comes on the terminal. Could you suggest how do I go about doing the last step: namely, writing to the terminal then reading the output? I'm a beginner in python, so please excuse me if this sounds trivial.

This makes use of the fact that precedence of and is higher than or. So <condition> and X or Y is basically (<condition> and X) or Y. If <condition> and X evaluates to True, there is no need to evaluate further, as anything True or Y is True. If <condition> and X evaluates to False, then Y is returned as False or Y is basically Y.

So I figured it out. What you need to do is find a community structure, either pre-defined or using one of the methods provided for community detection, such as infomap or label_propagation. This gives you a vertex clustering, which you can use to place on another graph and from that use .q to find the modularity.

I have two related graphs created in iGraph, A and G. I find community in structure in G using either infomap or label_propagation methods (because they are two that allow for weighted, directional links). From this, I can see the modularity of this community for the G graph. However, I need to see what modularity this will provide for the A graph. How can I do this?

Boto is a Python wrapper for AWS APIs. If you want to interact with AWS using its published APIs, you need boto/boto3 library installed. Boto will not be supported for long. So if you are starting to use Boto, use Boto3 which is much simpler than Boto. Boto3 supports (almost) all AWS services.

Boto is a python interface to Amazon Services (like copying to S3, etc). You don't need it to just run regular python as you would on any linux instance with python installed, except to access AWS services from your EC2 instance.

You don't need to define the EMAIL_BACKEND setting (it has a default), but you do need to define a setting module. You can set the DJANGO_SETTINGS_MODULE in your shell environment, or set os.environ['DJANGO_SETTINGS_MODULE'] to point to your settings module. Note that calling python manage.py shell will set up the Django environment for you, which includes setting DJANGO_SETTINGS_MODULE and calling django.setup(). You still need to call setup_test_environment() to manually run tests in your python shell.

I want to test a view in my Django application. So I open the python shell by typing python and then I type from django.test.utils import setup_test_environment. It seems to work fine. Then I type setup_test_environment() and it says django.core.exceptions.ImproperlyConfigured: Requested setting EMAIL_BACKEND, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. I don't need to send mails in my test, so why does Django wants me to configure an email back-end ? Are we forced to configure an email back-end for any test even if it doesn't need it ?

The homepage for the web application I'm testing has a loading screen when you first load it, then a username/password box appears. It is a dynamically generated UI element and the cursor defaults to being inside the username field. I looked around and someone suggested using action chains. When I use action chains, I can immediately input text into the username and password fields and then press enter and the next page loads fine. Unfortunately, action chains are not a viable long-term answer for me due to my particular setup. When I use the webdriver's find_element_by_id I am able to locate it and I am not able to send_keys to the element though because it is somehow not visible. I receive selenium.common.exceptions.ElementNotVisibleException: Message: element not visible. I'm also not able to click the field or otherwise interact with it without getting this error. I have also tried identifying and interacting with the elements via other means, such as "xpaths" and css, to no avail. They are always not visible. Strangely, it works with dynamic page titles. When the page first loads it is Loading... and when finished it is Login. The driver will return the current title when driver.title is called. Does anyone have a suggestion?

You can use RabbitMQ to schedule jobs asynchronously. This would be faster than multiple DB queries. Basically, this tool allows you to create a job queue (Containing UserID, StoreID & Timestamp) where workers can remove (at midnight if you want) and create your reports (or whatever your heart desires). This also allows you to scale your system horizontally across nodes. Your workers can be different machines executing these tasks. You will also be safe if your DB crashes (though you may still have to design redundancy for a machine running RabbitMQ service). DB should be used for persistent storage and not as a queue for processing.

I need to store some daily information in DynamoDB. Basically, I need to store user actions: UserID, StoreID, ActionID and Timestamp. Each night I would like to process the information generated that day, do some aggregations, some reports, and then I can safely deleted those records. How should I model this? I mean the hash key and the sort key... I need to have the full timestamp of each action for the reports but in order to query DynamoDB I guess it is easier to also save the date only. I have some PKs as UserID and StoreID but anyhow I need to process all data each night, not the data related to one user or one store... Thanks! Patricio

One of the simplest ways is just copying the site-package directory in the original winpython to the new one (It is assumed that the versions of two winpythons are the same, saying python 3.5). If you thinks the above way is silly, then you can use pip instead. Extract the installed packages from original winpython (pip used below should belong to the original winpython) pip freeze --all > python_packages.txt Install the extracted package list with pip. (pip used below should belong to the new winpython) pip install -r python_packages.txt

If you debug using pressing SHIFT-F9 it debugs the last file you debugged, which might be some file you debugged yesterday... To debug a new file press ALT-SHIF-F9. You can see these two different debugging options from the Run menu. There is Debug <last file> and there is Debug...

I am doing simple python coding in pycharm but the problem is whenever I debug it starts debugging some other file in my project and not the one I am working with. I did go to run-->edit configuration and check if my file was set for debugging and it was but still it debugs another file when I start debugging. any help will be appreciated

You can remove the white color, rebin the histogra and then compare: Compute a histrogram with 256 bins. Remove the white bin (or make it zero). Regroup the bins to have 64 bins by adding the values of 4 consecutive bins. Perform the compareHist(). This would work for any "predominant color". To generalize, you can do the following: Compare full histrograms. If they are different, then finish. If they are similar, look for the predominant color (with a 256-bin histogram), and perform the procedure described above, to remove the predominant color from the comparisson.

my program's purpose is to take 2 images and decide how similar they are. im not talking here about identical, but similarity. for example, if i take 2 screenshots of 2 different pages of the same website, their theme colors would probably be very similar and therefor i want the program to declare that they are similar. my problem starts when both images have a white background that pretty much takes over the histogram calculation (over then 30% of the image is white and the rest is distributed). in that case, the cv2.compareHist (using correlation method, which works for the other cases) gives very bad results, that is, the grade is very high even though they look very different. i have thought about taking the white (255) off the histogram before comparing, but that requires me to calculate the histogram with 256 bins, which is not good when i want to check similarity (i thought that using 32 or 64 bins would be best) unfortunately i cant add images im working with due to legal reasons if anyone can help with an idea, or code that solves it i would be very grateful thank you very much

PyCharm decides that certain parenthesis in my Python code are 'redundant'. I want to keep them anyway. So PyCharm started annoying me with green lines under them. I don't want to give in to PyCharm's quirks. I was able to ignore other warnings in the following way: File > Settings > Editor > Inspections > uncheck all warnings that you don't like.. Sadly, the 'redundant parentheses' warning does not appear in that list. How do I ignore this warning?

Thanks to @Oliver and @Daniel's comments that lead me to the answer why it did not work. I started the virtual environment on my Debian with python 3. virtualenv made the virtual environment but it was specifically for Debian. When I used it for mac, since it could not run the python executable in the virtual environment (since it is only compatible with Debian), hence, it used my Mac's system python, which is Python 2.7.10. In summary, as virtualenv uses the python executable on the system, when the python executable is run on another system, it will not work.

I am working on a django project on two separate systems, Debian Jessie and Mac El Capitan. The project is hosted on github where both systems will pull from or push to. However, I noticed that on my Debian, when I run python --version, it gives me Python 3.4.2 but on my Mac, it gives me Python 2.7.10 despite being in the same virtual environment. Moreover, when I run django-admin --version on my Debian, it gives me 1.10 while on my Mac, 1.8.3. This happens even when I freshly clone the projects from github and run the commands. Why is it that the virtual environment does not keep the same version of python and django?

I see multiple solutions : When you first create your images in the first folder, add a suffix to their name, for instance, filexxx.jpg.part and when they are fully written just rename them, removing the .part. Then in your watchdog, be sure not to work on files ending with .part In your watchdog, test the image file, like try to load the file with an image library, and catch the exceptions.

I'm currently working on a project that adds images to a folder. As they're added they also need to be moved (in groups of four) to a secondary folder overwriting the images that are already in there (if any). I have it sort of working using watchdog.py to monitor the first folder. When the 'on_created' event fires I take the file path of the newly added image and copy it to the second folder using shutil.copy(), incrementing a counter and using the counter value to rename the image as it copies (so it becomes folder/1.jpg). When the counter reaches 4 it resets to 0 and the most recent 4 images are displayed on a web page. All these folders are in the local filesystem on the same drive. My problem is that sometimes it seems the event fires before the image is fully saved in the first folder (the images are around 1Mb but vary slightly so I can't check file size) which results in a partial or corrupted image being copied to the second folder. At worst it throws an IOError saying the file isn't even there. Any suggestions. I'm using OSX 10.11, Python 2.7. The images are all Jpegs.

How can I check a file has been copied fully to a folder before moving it using python

I need to run some code every time my application starts. I need to be able to manipulate models, just like I would in actual view code. Specifically, I am trying to hack built-in User model to support longer usernames, so my code is like this def username_length_hack(sender, *args, **kwargs): model = sender._meta.model model._meta.get_field("username").max_length = 254 But I cannot seem to find the right place to do it. I tried adding a class_prepared signal handler in either models.py or app.py of the app that uses User model (expecting that User will by loaded by the time this apps models are loaded). The post_migrate and pre_migrate only run on migrate command. Adding code into settings.py seems weird and besides nothing is loaded at that point anyway. So far, the only thing that worked was connecting it to a pre_init signal and having it run every time a User instance is spawned. But that seems like a resource drain. I am using Django 1.8. How can I run this on every app load?

That's terribly slow. I run backtest on 350k+ min bars, including multiple signal generations, portfolio optimization, rebalancing, and execution priority algorithm, in around 40 mins. Pure python, no pandas, jit, or cython. IMO, it will depend a lot on the level of sophistication and complexity on the many of your moving parts.

I'm current developing an event-driven backtesting engine in Python. I would like to have an idea about how fast a high speed backtesting engine should be, especially in Python. Right now, I can replay one year of 1 min bar data about 10 hours.Is it fair to say the speed now is acceptable? I know there are some open source backtesting engine on Github, like Pipline. I don't really know whether it is event-driven , because I did not play around with it before. Anyone has a good idea of how fast a good quality event driven backtesting engine should be ? Thank you so much for your help.

Here's another option. You could separate different test categories by directory. If you wanted to try this strategy, it may look something like: python -modules unit -pure unit test modules functional -other unit test modules In your testing pipeline, you can call your testing framework to only execute the desired tests. For example, with Python's unittest, you could run your 'pure unit tests' from within the python directory with python -m unittest discover --start-directory ../unit and the functional/other unit tests with python -m unittest discover --start-directory ../functional An advantage of this setup is that your tests are easily categorized and you can do any scaffolding or mocked up services that you need in each testing environment. Someone with a little more Python experience might be able to help you run the tests regardless of the current directory, too.

I am working on a project that has many "unit tests" that have hard dependencies that need to interact with the database and other APIs. The tests are a valuable and useful resource to our team, but they just cannot be ran independently, without relying on the functionality of other services within the test environment. Personally I would call these "functional tests", but this is just the semantics already established within our team. The problem is, now that we are beginning to introduce more pure unit tests into our code, we have a medley of tests that do or do not have external dependencies. These tests can be ran immediately after checking out code with no requirement to install or configure other tools. They can also be ran in a continuous integration environment like jenkins. So my question is, how I can denote which is which for a cleaner separation? Is there an existing decorator within unit testing library?

I had this exact question myself, with a PHP project, though. My solution was to use ElasticSearch as an intermediate cache between the application and database. The trick to this is the ORM. I designed it so that when Entity.save() is called it is first stored in the database, then the complete object (with all references) is pushed to ElasticSearch and only then the transaction is committed and the flow is returned back to the caller. This way I maintained full functionality of a relational database (atomic changes, transactions, constraints, triggers, etc.) and still have all entities cached with all their references (parent and child relations) together with the ability to invalidate individual cached objects. Hope this helps.

For my app, I am using Flask, however the question I am asking is more general and can be applied to any Python web framework. I am building a comparison website where I can update details about products in the database. I want to structure my app so that 99% of users who visit my website will never need to query the database, where information is instead retrieved from the cache (memcached or Redis). I require my app to be realtime, so any update I make to the database must be instantly available to any visitor to the site. Therefore I do not want to cache views/routes/html. I want to cache the entire database. However, because there are so many different variables when it comes to querying, I am not sure how to structure this. For example, if I were to cache every query and then later need to update a product in the database, I would basically need to flush the entire cache, which isn't ideal for a large web app. I would prefer is to cache individual rows within the database. The problem is, how do I structure this so I can flush the cache appropriately when an update is made to the database? Also, how can I map all of this together from the cache? I hope this makes sense.

How do I structure a database cache (memcached/Redis) for a Python web app with many different variables for querying?

Adding to Edward's answer, I believe the PyEZ RPC calls are implemented using reflection (__call__ method), so today it is not aware of valid RPC calls nor args. The way to make it aware would be to load the Netconf schema dynamically from the device and use that to map the named arg to a tag or an element. A potential issue from trying to abstract this calling convention from the user is what to do when there is a tag and an element with the same name for the same RPC – not sure if that is the case today or there are rules to prevent this in the schemas, but in that case the user of the call should be able to control what goes in the RPC doc IMHO.

When using RPC calls in PyEZ we add the parameters as named arguments like rpc.get_interface_information(terse="True", interface-name="xe-0/0/0"), however for configuration the options need to be within a dictionary like rpc.get_configuration({"inherit":"inherit", "groups":"groups"}) What's the reason for these differences?

PyEZ RPC options format differ between get_configuration and other calls

Though you already might have solved the problem: You could use 2 Queues instead of one. produce -> Q1 -> Direct Exchange -> Q2 -> consume Then you can dynamically delete the binding (API call "unbind") between the Exchange and the Q2. Then Q2 drains empty and Msg queue in Q1 until you bind it again after your maintenance. I wish there was something like "Pause Queue for x-Minutes" to implement a simple retry mechanism.

I'm looking for a way to block message delivery for a moment and reactivate it without loosing the messages. The case is when we need to migrate consumers, I don't want messsages to be delivered for like 10 minutes. I want to block queue delivery and then reactivate it. Is there a way to do this? In Python or in PHP? EDIT: With this process I don't want to get consumers disconnected. I want it like putting the queue on hold, no message delivered to current consumers and then "reactivate it".

We are in the process of releasing a new feature that can update the schema of the destination table within a load/query job. With autodetect and the new feature you can directly load the new data to the existing table, and the schema will be updated as part of the load job. Please stay tuned. The current ETA is 2 weeks.

Background I studied and found that bigQuery doesn't accept schemas defined by online tools (which have different formats, even though meaning is same). So, I found that if I want to load data (where no. of columns keeps varying and increasing dynamically) into a table which has a fixed schema. Thoughts What i could do as a workaround is: First check if the data being loaded has extra fields. If it has, a schema mismatch will occur, so first you create a temporary table in BQ and load this data into the table using "autodetect" parameter, which gives me a schema (that is in a format,which BQ accepts schema files). Now i can download this schema file and use it,to update my exsisting table in BQ and load it with appropriate data. Suggestion Any thoughts on this, if there is a better approach please share.

You can't use RAM for the input and output file using the Ghostscript demo code, it doesn't support it. You can pipe input from stdin and out to stdout but that's it for the standard code. You can use the Ghostscript API to feed data from any source, and you can write your own device (or co-opt the display device) to have the page buffer (which is what the input is rendered to) made available elsewhere. Provided you have enough memory to hold the entire page of course. Doing that will require you to write code to interface with the Ghostscript shared object or DLL of course. Possibly the Python library does this, I wouldn't know not being a Python developer. I suspect that the pointer from John Coleman is sufficient for your needs though.

I installed all libraries on this version of ipython, for example I have matplotlib on ipython but not on python. I do not want to re-install everything again on the brew python, rather continue to install libraries on this version of ipython. How can I install new libraries there?

Try opening in the page in Chrome and hitting F12 - there's a tonne of developer tools and web page debuggers in there. For your particular question about loading order, check the Network tab, then hit refresh on your page - it'll show you every file that the browser loads, starting with the HTML in your browsers address bar. If you're trying to figure out javascript, check out the Sources tab. It even allows you to create break points -very handy for following along with a page is doing.

Ok, this question is going to sound pretty dumb, but I'm an absolute novice when it comes to web development and have been tasked with fixing a website for my job (that has absolutely nothing in the way of documentation). Basically, I'm wondering if there is any tool or method for tracking the order a website loads files when it is used. I just want to know a very high-level order of the pipeline. The app I've been tasked with maintaining is written in a mix of django, javascript, and HTML (none of which I really know, besides some basic django). I can understand how django works, and I kind of understand what's going on with HTML, but (for instance) I'm at a complete loss as to how the HTML code is calling javascript, and how that information is transfered back to HTML. I wish I could show the code I'm using, but it can't be released publicly. I'm looking for what amounts to a debugger that will let me step through each file of code, but I don't think it works like that for web development. Thank you

It's really easy. You can debug your script by pressing Alt+F5 or the bug button in Pycharm IDE. After that the Debugger handle the execution of the script. now you can debugging line by line by F10, get into a function or other object by pressing F11. Also there is Watch Window where you can trace your variable values while debugging. I really encourage you to search blogs on internet. There are lots of tutorial in this area

I have reached the stage in developing my Django project where I need to start debugging my code, as my site is breaking and I don't know why. I'm using Pycharm's IDE to code, and the debugger that comes with it is super intimidating! Maybe because I am a total newbie to programming (been coding only since May) but I don't really understand how debugging, as a basic concept, works. I've read the Pycharm docs about debugging, but I'm still confused. What is the debugger supposed to do/how is it supposed to interact with your program? What helpful info about the code is debugging supposed to offer? When I previously thought about debugging I imagined that it would be a way of running through the code line by line, say, and finding out "my program is breaking at this line of code," but "stepping through my code" seems to take me into files that aren't even part of my project (e.g. stepping into my code in admin.py will take me into the middle of a function in widgets.py?) etc. and seems to present lots of extra/confusing info. How do I use debugging productively? How can I use it to debug my Django webapp? Please help! TIA :)

Can someone explain debugging / Pycharm's debugger in an easy to understand way?

I had the same issue: Installed Python 27 Tried to use pip, but failed with unrecognized command error Checked installation: no "C:\Python27\Scripts", only "C:\Python27\Tools\Scripts" This issue happens only on some versions of Windows. HOW TO FIX IT: Uninstall Python 27 Reinstall Python 27, but unselect "pip" feature Check installation: no "C:\Python27\Scripts" as expected Start the installer again and use "Change Python" Set "pip" and "Add Python.exe to Path" features to be installed Check installation: "C:\Python27\Scripts" is now correctly present So for some unknown reason, pip is not correctly installed on some versions of Windows if it is installed during default Python 27 setup. To fix this issue, pip must be installed afterwards using the "Change Python" setup.

I have Python 2.7.11 installed on my machine which to my understanding should come with pip, however when I check the C:\Python27\Tools\Scripts\ directory there is no pip.exe present. I have tried completely removing and reinstalling Python 2.7.11 without success. Running the installer pip is set to be installed, but after the install pip is nowhere to be found. I also have Python 3.4 installed which has pip as expected. Any thoughts?

I encountered the same problem - pip not installed - with python-2.7.16, Win10, installing for 'all users'. It was resolved when I allowed the MSI installer to target the default location (C:\Python27) rather than changing it to under Program Files (x86). I've no clue why this changed anything.

Had the issue where no matter which version of python 2.7 I installed on windows 10 there was no pip.exe generated in the "Scripts" folder. I solved it by ensuring that that MSI Installer file had Admin privileges before installing
