It's a warning message, printed via log.warn in bdist_egg.py. It probably should include the word 'warning', and I'm not sure why it doesnt. The warning is raised by scan_module, which is used to determine if the package can be zip compressed or not. You'd probably have to check the mailing list to see why stack introspection prevents compressed eggs, but at a guess I'd say zip compression might mess with line number information handed to inspect. Referencing __file__ or __path__ will also get the package flagged as not zip safe.

When I build/install my package, the line [package.module]: module MAY be using inspect.stack prints to the log. It doesn't preface this with "warning" or "error", but it seems like a strange thing to print in the midst of the other information (e.g., "creating...egg", "Extracting...to...site-packages". Is there some reason that I shouldn't be using inspect.stack() within my package? If there is no reason, then why does this one function (out of the hundreds used) result in this strange notification?

Why does log print "module MAY be using inspect.stack"

I think you already read this : "To create a snapshot for EBS volumes that serve as root devices, you should stop the instance before taking the snapshot." This is typical sysops operation. Unless you are 100% sure that no cache data pending writing to EBS block, then you can create EBS snapshot without stopping instances. HOWEVER, if such EBS is used to launch your instances (as mentioned above), part of the OS swap spaces might sit inside EBS, this is still not very serious, since you can recreate swap. But you will NEVER want to deal with partially written OS update (that might run in the background ) If your EBS is used as Database store, then you should stop ALL services that tap into the EBS. In fact, stopping the instances is 100% guarantee that no forgotten services(that you launch and not sure what they are doing) writing to EBS. A corrupted EBS snapshot is not something snapshot make for.

Is it possible to create snapshot for EBS without a reboot. I'm planing to write a script to take snapshots on regular basics for running instances(Using python boto module). I go through the boto documentation, but didn't find any. Can someone please help on this.

While I admire, and am somewhat baffled by, the documentation's commitment to mediating everything related to TensorFlow Serving through Bazel, my understanding of it is tenuous at best. I'd like to minimize my interaction with it. I'm implementing my own TF Serving server by adapting code from the Inception + TF Serving tutorial. I find the BUILD files intimidating enough as it is, and rather than slogging through a lengthy debugging process, I decided to simply edit BUILD to refer to the .cc file, in lieu of also building the python stuff which (as I understand it?) isn't strictly necessary. However, my functional installation of TF Serving can't be imported into python. With normal TensorFlow you build a .whl file and install it that way; is there something similar you can do with TF Serving? That way I could keep the construction and exporting of models in the realm of the friendly python interactive shell rather than editing it, crossing all available fingers, building in bazel, and then /bazel-bin/path/running/whatever. Simply adding the directory to my PYTHONPATH has so far been unsuccessful. Thanks!

At this point, you cannot do this, we have to pass a key (Partition key or Partition key and sort key) to update the item. Currently, the only way to do this is to scan the table with filters to get all the values which have 0 in "updated" column and get respective Keys. Pass those keys and update the value. Hopefully, in future AWS will come up with something better.

I want to set all the 'updated' field to '0' without having to providing a key to avoid fetch and search in the table. I tried batch write, but seems like update_item required Key inputs. How could I update the entire column to have every value as 0 efficiently please? I am using a python script. Thanks a lot.

Can you create a C# class that calls a Python script without using Iron Python and without using any external API? No. That is not possible. You have a few other choices: Integrate the Python runtime into your program. Smead already described one way to do this. It will work, and it does avoid creating another process, but it will be a lot of work to get it running, and it is still technically using an API. I do not recommend this for a single Python script where you don't need to pass data back and forth, but it's good to know that option exists if your other options don't pan out. Use the Process module. This is probably what I would do. Process has security concerns when a malicious user can cause you to execute bogus shell commands, or if the malicious user can replace the contents of the Python script. It is quite safe when you can lock down those two things. The speed is unlikely to be a concern. It will literally only take a few minutes to set up a C# program with a process call, so if your mentor is concerned about speed, just write it and measure the speed to see if it's actually a problem. Consider rewriting the script in C# C# is a very expressive language with a very strong standard library, so assuming your script is not thousands of lines long, and does not use any obscure Python libraries, this might actually not be much work. If you really must not use Process, this would be the next solution I would consider.

I have a python code. I need to execute the python script from my c# program. After searching a bit about this, I came to know that there is mainly two ways of executing a python script from c#. One by using 'Process' command and the other by using Iron Python. My question might seem dumb, is there any other way through which I can execute a python script? To be more specific, can I create a class , lets say 'Python' in c# and a member function 'execute_script' which doesn't use any api like iron python or doesn't create a process for executing the script, so that if call 'execute_scipt(mypythonprogram.py)' , my script gets executed. Sorry if this seems dumb. If this is possible, please do help me. Thanks in advance.

First, I would check that you are using the correct python (i.e. which python and confirm that it is the python in your conda environment). Next, you can check if your package is in the site-packages directory of that same python. The most likely thing, I'd bet, is that the conda package doesn't include everything correctly. Are you sure that you have a build.sh (or bld.bat if you are on windows) and a setup.py? Did you try expanding your built conda package and looking for your python classes in there? If you expand your built conda package, probably something like gender_univ-VERSION-py35_0.tar.bz2, you should see a lib/python3.5/site-packages/gender_univ directory (i.e. python package). Do you? If not, then the failure is with your building.

I built a python3 package called gender_univ using the Anaconda conda build command. I uploaded the package to the Anaconda cloud and then installed it into my conda environment. Though the package shows up in the list of installed packages when I type conda list, whenever I try to access the package using import gender_univ I get the error no module named gender_univ. I want to understand why I can't seem to import a package that is apparently installed in my conda virtual environment? Any suggestions.

Of course you can. When you are running the first process, the unmodified code is loaded into memory,like a copy in memory. When you edit the running code, it makes another copy into memory, you won't change the original one. And even though you click save, it won't make any change to the code in the memory that the first process is using. But as you say, your program is very long. If you change a package the program hasn't used, it may cause the problem, coz the import part is loaded when the program execute the import part.

We ended up using git dependencies and not devpi. I think when git is used, there is no need to add another package repository as long as pip can use this. The core issue, where the branch code (because of a second level dependency) is different from the one merged to master is not solved yet, instead we work around that by working to remove that second level dependency.

We are trying to find the best way to approach that problem. Say I work in a Python environment, with pip & setuptools. I work in a normal git flow, or so I hope. So: Move to feature branch in some app, make changes. Move to feature branch in a dependent lib - Develop thing. Point the app, using "-e git+ssh" to the feature branch of the dependent lib. Create a Pull Request. When this is all done, I want to merge stuff to master, but I can't without making yet another final change to have the app (step 3 above) requirements.txt now point to the main branch of the feature. Is there any good workflow for "micro services" or multiple dependent source codes in python that we are missing?

I think you however need a server(or it can be just file-share service). If I got it correctly you need to control(or just update) Raspberry(ies), that connected to internet via 3G. So, there are options I see: Connect them into VPN; Write script that always be checking for new update for your app from a http\ftp file-sharing server; Use reverse-shell, but working depends on NAT specs that uses 3G provider.

I am currently developing a python program for a Raspberry Pi. This Raspberry is meant to control a solar panel. In fact, there will be many Raspberry(ies) controlling solar panels and they will be connected to each others by RJ wires. The idea is that every Raspberry has the same status, there is not any "server" Raspberry and "client" Raspberry. The program will receive GPS data, i.e. position, time... Except from the GPS data, the Raspberry(ies) will not have direct internet access. However, it will be possible to plug a 3G key in order to gain access to internet. The problem is the following : I want to update my python program remotely, by internet provided by my 3G key (the solar panels are in a field, and I'm home for instance so I do not want to drive a hundred miles to get my Raspberry(ies) back and update them manually...). How is it possible to make the update remotely considering that I do not have a real "server" in my network of Raspberry(ies)?

How can I update a python program remotely on linux?

always split your data to train and test split to prevent overfiting. if some of your features has big scale and some doesnt you should standard the data.make sure to sandard the data only on the train set not to couse overfiting. you also have to look for missing datas and replace or remove them. if less than 0.5% of the data in a column is missing you can use 'dropna' otherwise you have to replace it with something(you can replace ut with zero,mean,the previous data...) you also have to check outliers by using boxplot. outliers are point that are significantly different from other data in the same group can also affects your prediction in machine learning. its the best if we check the multicollinearity. if some features have correlation we have multicollinearity can couse wrong prediction for our model. for using your data some of the columns might be categorical with sholud be converted to numerical.

I figured out a way to get the data, it was pretty straight forward to be honest, albeit a little hackish. This might not work in other cases, especially if there is latency, but I could also be misunderstanding what's happening: When the connection opens, the server spits out two messages, one saying it can't chdir to a particular directory, then a few milliseconds later it spits out another message stating that you need to connect to the other IP. If I send a command immediately after connecting (doesn't matter what command), exec_command will interpret this second message as the response. So for now I have a solution to my problem as I can check this string for a known message and change the flow of execution. However, if what I describe is accurate, then this may not work in situations where there is too much latency and the 'test' command isn't sent before the server response has been received. As far as I can tell (and I may be very wrong), there is currently no proper way to get the stdout stream immediately after opening the connection with paramiko. If someone knows a way, please let me know.

I'm writing a script that uses paramiko to ssh onto several remote hosts and run a few checks. Some hosts are setup as fail-overs for others and I can't determine which is in use until I try to connect. Upon connecting to one of these 'inactive' hosts the host will inform me that you need to connect to another 'active' IP and then close the connection after n seconds. This appears to be written to the stdout of the SSH connection/session (i.e. it is not an SSH banner). I've used paramiko quite a bit, but I'm at a loss as to how to get this output from the connection, exec_command will obviously give me stdout and stderr, but the host is outputting this immediately upon connection, and it doesn't accept any other incoming requests/messages. It just closes after n seconds. I don't want to have to wait until the timeout to move onto the next host and I'd also like to verify that that's the reason for not being able to connect and run the checks, otherwise my script works as intended. Any suggestions as to how I can capture this output, with or without paramiko, is greatly appreciated.

You could use atexit.register() from module atexit to register cleanup functions. If you register functions f, g, h in that order. At program exit these will be executed in the reverse order, h, g, f. But one thing to note: These functions will be invoked upon normal program exit. Normal means exits handled by python.

The easiest way to accomplish this that I can think of is to use Calculate Field. In this case, the script would be: FC = path to shapefile field = "ROWID" arcpy.CalculateField(FC, field, '!Liber! + !Page!', "PYTHON_9.3")

I searched for a question similar to mine, but couldn't find something precisely similar, so if this has been answered already, I apologize. I am creating a ROW shapefile that contains (among others) 3 fields: "Liber" "Page" "ROWID" Currently I have "Liber" and "Page" set as text values (though that may later change to a numerical data type), and "ROWID" as a text value. Is it possible to write a script that will automatically calculate "ROWID" as: "ROW-" + !Liber! + !Page! I'm trying to set this up for someone to enter data without needing to do much more than enter values in the "Liber" and "Page" fields. If it isn't possible to do it this way, how can I set it so that someone can right-click the "ROWID" field, select "Calculate Values" (which I actually can't find anymore; did they remove this from outside the Geoprocessing Toolbox?), and have it run the above Python script? I can't really expect the data entry person to run the field calculator every time they need to calculate a new "ROWID" value, unfortunately. Please let me know if this isn't making sense. Thank you!

I have a numpy array U with shape (20, 50): 20 spatial points, in a space of 50 dimensions. How can I transform it into a (20, 1, 50) array, i.e. 20 rows, 1 column, and each element is a 50 dimension point? Kind of encapsulating each row as a numpy array. Context The point is that I want to expand the array along the columns (actually, replicating the same array along the columns X times) using numpy.concatenate. But if I would do it straight away I would not get the result I want. E.g., if I would expand it once along the columns, I would get an array with shape (20, 100). But what I would like is to access each element as a 50-dimensional point, so when I expand it I would expect to have a new U' with shape (20, 2, 50).

The Short, Simple Answer You should probably give them none of those things. They are equivalent to handing over your username and password to someone. The Longer Answer It depends... Personal Access Tokens Your personal access token is a unique token that authorises and represents you during API calls, the same way that logging via the web interface authorises you to perform actions there. So when you call an API function with a personal access token, you are performing that API action as if you yourself had logged in and performed the same action. Therefore, if you were to give someone else your token, they would have the same access to the site as they would have if you gave them you username and password combination. Personal access tokens have attached scopes. Scopes control exactly how much access to GitHub a particular token has. For example, one token my have access to all private repositories, but another token only to public ones. Client IDs A client ID represents your application, rather than you. So when you create an application, GitHub gives you an ID that you use to identify your application to GitHub. Chiefly this allows someone logging into your application using OAuth to see on the GitHub web interface that it's your particular application requesting access to their account. Client Secrets A client secret is a random, unguessable string that is used to provide an extra layer of authentication between your application and GitHub. If you think of the client ID as the username of your application, you can think of the client secret as the password. Should I Share Them? Whether you wish to share any of these things depends largely on how much you trust the other developers. If you are all working on the same application, it's likely that you will all know the client ID and client secret. But if you want to develop an open-source application that people will install on their own machines, they should generate their own client ID and secrets for their own instances of the app. It's unlikely that you should ever share a personal access token, but if you have a bot account used by the whole team, then sharing the tokens could also be okay.

I am writing a basic python script and I am trying to use the Github API. Because I am new to the development scene, I am unsure of what I can share with other developers. Do I generate a new personal access token (that I assume can be revoked) or do I give them Client ID and Client Secret? Can someone explain how OAuth (Client ID and Client Secret) is different from a personal access keys? Does this logic work across all APIs (not just on Github's)?

Its a hint saying that the method can be a static method since it is not acting on instances (ie, you are passing in self but aren't actually making use of it). There is no conventional means to handle it - either you want that method to be there, because you are creating a class tree and want it to be defined/overridden in the descendants; or for whatever other reason. In this case, you can ignore the warning. This is entirely different than @staticmethod; which has a lot of other consequences. So its not a matter of "if I'm not using self, but passing it in, lets just make it a static method"; you have to know what the method is doing. Static and class methods are most often used in factory classes.

In PyCharm, whenever you declare a method that doesn't make use of the self variable it gives you the warning Method 'method_name' may be 'static' I've come across this warning many times and most of the time I just ignore it. However, I was wondering if there is a conventional or pythonic way to handle it. So basically, my question is what should I do when I come across this? Should I ignore it? Should I replace it with a static method (@staticmethod)?

What if a method doesn't use self?

There is no dinner for free even if some marketing blable offers that, do not take it for granted. Efficient means usually a complex resources handling. Simplest to implement usually fights with overheads & efficient resources handling. Simplest? Using sir Henry FORD's point of view, a component, that is not present in one's design simply cannot fail. In this very sense, we strive here not to programmatically control anything beyond the simplest possible use of elementary components of an otherwise smart ZeroMQ library: Scenario SIMPLEST: Rule a) The central HQ-unit ( be it just a thread or a fully isolated process ) .bind()-s it's receiving port ( pre-set as a ZMQ_SUBSCRIBE behaviour-archetype ) and "subscribes" it's topic-filter to "everything" .setsockopt( ZMQ_SUBSCRIBE, "" ) before it spawns the first DAQ-{ thread | process }, further ref'd as DAQ-unit. Rule b) Each DAQ-unit simply .connect()-s to an already setup & ready port on the HQ-unit with a unit-local socket access-port, pre-set as a ZMQ_PUBLISH behaviour-archetype. Rule c) Any DAQ-unit simply .send( ..., ZMQ_NOBLOCK )-s as needed it's local-data via a message, which is being delivered in the background by the ZeroMQ-layer to the hands of the HQ-unit, being there queued & available for a further processing at the HQ-unit's will. Rule d) The HQ-unit regularly loops and .poll( 1 )-s for a presence of a collected message from any DAQ-unit + .recv( ZMQ_NOBLOCK ) in case any such was present. That's all Asynchronous: yes. Non-blocking: yes. Simplest: yes. Scaleable: yes. Almost linearly, until I/O-bound ( still some tweaking possible to handle stressed-I/O-operations ) as a bonus-point...

The parent process launches a few tens of threads that receive data (up to few KB, 10 requests per second), which has to be collected in a list in the parent process. What is the recommended way to achieve this, which is efficient, asynchronous, non-blocking, and simpler to implement with least overhead? The ZeroMQ guide recommends using a PAIR socket archetype for coordinating threads, but how to scale that with a few hundred threads?

If simply loading the json is too heavy for the browser, then doing a complete rendering server-side would not help, as the rendered object would one way or another include the same amount of data. But I guess you cannot show that much data at once. Since you are going for a zoomable visualizer, you should probably only load the data that is visible at the current scale, within the current window (just like any map application does: you can't just load the whole world-map at street level at once, but zooming can still go smoothly). Quadtrees are normally quite useful for this task.

So my issue is that I'm passing a large JSON file (I'm not sure of the exact size, but it's very very big) into a D3 zoomable treemap. I'm doing this by way of AJAX call to a Python backend. The performance of my browser just degrades completely when I load the file in, it takes 5-10 mins for it to even appear. I'm just wondering are there any options that will help with performance? Rendering it server side perhaps? This is the first ever time I've run into a performance issue like this so I'm really not sure where to go. Any help would be appreciated.

What you are doing is perfectly fine. You are generating the analytic signal to accommodate the negative frequencies in the same way a discrete Hilbert transform would. You will have some scaling issues - you need to double all the non-DC and non-Nyquist signals in the real frequency portion of the FFT results. Some practical concerns are that this method imparts a delay of the window size, so if you are trying to do this in real-time you should probably examine using a FIR Hilbert transformer and the appropriate sums. The delay will be the group delay of the Hilbert transformer in that case. Another item of concern is that you need to remember that the DC component of your signal will also shift along with all the other frequencies. As such I would recommend that you demean the data (save the value) before shifting, zero out the DC bin after you FFT the data (to remove whatever frequency component ended up in the DC bin), then add the mean back to preserve the signal levels at the end.

1

So I am trying to perform a frequency shift on a set of real valued points. In order to achieve a frequency shift, one has to multiply the data by a complex exponential, making the resulting data complex. If I multiply by just a cosine I get results at both the sum and difference frequencies. I want just the sum or the difference. What I have done is multiply the data by a complex exponential, use fft.fft() to compute the fft, then used fft.irfft() on only the positive frequencies to obtain a real valued dataset that has only a sum or difference shift in frequency. This seems to work great, but I want to know if there are any cons to doing this, or maybe a more appropriate way of accomplishing the same goal. Thanks in advance for any help you can provide!

In python, If I perform an fft on complex data, then irfft only the positive frequencies, how does that affect the data?

The easiest thing to do is (if there are no worries on security aspects) also a permanent fix. open the jenkins.xml file and add the following <arguments>-Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -Dhudson.model.DirectoryBrowserSupport.CSP="" -jar "%BASE%\jenkins.war" -- httpPort=8080 --webroot="%BASE%\war"</arguments> restart the jenkins server rerun your jenkins jobs to see the result files. If we are using the script console, every time you restart the jenkins server, the changes will be lost.

You are already doing a lot of preprocessing. The only additional step I recommend is to normalize the values after PCA. Then your data should be ready to be fed into your learning algorithm. Or do you want to avoid PCA? If the correlation between your features is not too strong, this might be ok. Then skip PCA and just normalize the values.

In rest_framework.request.Request request.body is bytes, which is always available, thus there is no limit in usage request.data is a "property" method and can raise an exception, but it gives you parsed data, which are more convenient However, the world is not perfect and here is a case when request.body win Consider this example: If client send: content-type: text/plain and your REST's endpoint doesn't accept text/plain your server will return 415 Unsupported Media Type if you access request.data But what if you know that json.loads(request.body) is correct json. So you want to use that and only request.body allow that. FYI: A described example is a message of AWS SNS notification sent by AWS to HTTP endpoint. AWS SNS works as a client here and of course, this case is a bug in their SNS. Another example of benefits from request.body is a case when you have own custom parsing and you use own MIME format.

Django REST framework introduces a Request object that extends the regular HttpRequest, this new object type has request.data to access JSON data for 'POST', 'PUT' and 'PATCH' requests. However, I can get the same data by accessing request.body parameter which was part of original Django HttpRequest type object. One difference which I see is that request.data can be accessed only one time. This restriction doesnt apply to request.body. My question is what are the differences between the two. What is preferred and what is the reason DRF provides an alternative way of doing same thing when There should be one-- and preferably only one --obvious way to do it. UPDATE: Limiting the usecase where body is always of type JSON. Never XML/ image or conventional form data. What are pros/cons of each?

Solved using scipy library import scipy.misc ...(code) scipy.misc.imsave(name,array,format) or scipy.misc.imsave('name.ext',array) where ext is the extension and hence determines the format at which the image will be stored.

I would like to save a numpy matrix as a .png image, but I cannot do so using the matplotlib since I would like to retain its original size (which apperently the matplotlib doesn't do so since it adds the scale and white background etc). Anyone knows how I can go around this problem using numpy or the PIL please? Thanks

It is a lot safer to change your environment so that Python 3.5 is given preference over the default Python. There are many ways to do this; if you do them all, it provides the maximum compatibility. You can set these in your .bash_profile file, which is a hidden file in your home directory. You can set the PATH environment variable so that Python 3.5 appears first in the search order; like this PATH='/path/to/your/python3.5/directory':$PATH You can set a local alias in your shell, so that the python command points to Python 3.5, like this alias python="/path/to/the/file/python3.5" Once you set the above, make sure you restart the terminal application. If you download the installer form python.org; it will set these environment variables for you. Also, if you use a utility like brew it will set the shell up correctly for you. This will ensure that the shell environment will point to version of Python you want; however this does not affect applications that run on the desktop as most of them don't read the shell environment variables. So, if you are using and IDE like PyCharm you'll still have to manually set the correct Python version for your projects. This may seem like a lot of workaround, but on most Linux systems and even on OSX, Python is a core part of the system and it is used by some utilities, therefore it is always dangerous to rip and replace the version of Python that came with the operating system.

just a quick question. I have Python 2.7 on my mac by default. I have also installed 3.4 and use it more than 2.7, but would like to upgrade to the new 3.5. Should I remove 3.4 and just lay down a new install of 3.5, or is there a way to just update it. All my searches just talk about upgrading from 2.7 to 3x. I am just concerned about messing one of the installs up. Any input would be greatly appreciated. Cheers.

I am trying to work out how I can compare a list of words against a string and report back the word number from list one when they match. I can easily get the unique list of words from a sentence - just removing duplicates, and with enumerate I can get a value for each word, so Mary had a little lamb becomes 1, Mary, 2, had, 3, a etc. But I cannot work out how to then search the original list again and replace each word with its number value (so it becomes 1 2 3 etc). Any ideas greatly received!

You can keep a hash (an associative array) mapping column values to open output file handles, and open an output file only if none is open for that column value yet. This will be good enough unless you'll hit your limit on maximum number of open files. (Use ulimit -Hn to see it in bash.) If you do, either you need to close file handles (e.g. a random one, or the one that hasn't been used the longest, which is easy to keep track of in another hash), or you need to do multiple passes across the input, processing only as many column values as you can open output files in one pass and skipping them in future passes.

Yes, there is a shortcut for commenting out lines in Python 3.6 (Spyder). For Single Line Comment, you can use Ctrl+1. It will look like this #This is a sample piece of code For multi-line comments, you can use Ctrl+4. It will look like this #============= \#your piece of code \#some more code \#============= Note : \ represents that the code is carried to another line.

I know this is a while as to when i asked the question. I finally fixed this by changing the hosts. I went for Digital Oceans (created a new droplet) which supports wsgi. I deployed the app using gunicorn (application server) and nginx (proxy server).

I followed the hostgator django installation wiki and i deployed my app. The issue is that i am getting a 500 error internal page when entering the site url in the browser. I contacted the support team but could not provide enough info on troubleshooting the error Premature end of script headers: fcgi.This was the error found on the server error log. I am installed django 1.9.5 on the server and from the django documentation it does not support fastcgi. So my question 500 error be caused by the reason that i am running django 1.9.5 on the server and it does not support fastcgi. if so do i need to install lower version of django to support the fastcgi supported by hostgator shared hosting First i thought the error was caused by my .htaccess file but it has no issue from the what i heard from support team. Any Leads to how i can get the app up and running will be appreciated. This is my first time with django app deployment. Thank you in advance

As you say, Django 1.9 does not support FastCGI. You could try using Django 1.8, which is a long term support release and does still support FastCGI. Or you could switch to a different host that supports deploying Django 1.9 with wsgi.

I'm searching for a way to get the path of the directory of the file that I have chosen by QFileDialog.getOpenFileName(). I know that you can access it by os.path.dirname(os.path.realpath(filename), but I'm searching for a better way because I need to work in this directory. I don't really understand why you can access the file by open(filename, 'r') though your current working directory (when typing print(os.getcwd()) is not the directory of the file. Maybe there is a way by accessing something like the current working directory of the Qt.Application, but I had no success.. Also I have functions where you need arg1 = directory and arg2 = filename1 (in the directory) as arguments. Funnily enough they suddenly seem to work with just(!) arg1 = 'C:' as directory and arg2 = filename2 when filename2 is the file I've accessed by QFileDialog.getOpenFileName(). I'm happy about any explanation!

Try increasing the number of hidden units and the learning rate. The power of neural networks comes from the hidden layers. Depending on the size of your dataset, the number of hidden layers can go upto a few thousands. Also, please elaborate on the kind, and number of features you're using. If the feature set is small, you're better off using SVMs and RandomForests instead of neural networks.

I am currently working on some project related to machine learning. I extracted some features from the object. So I train and test that features with NB, SVM and other classification algorithms and got result about 70 to 80 % When I train the same features with neural networks using nolearn.dbn and then test it I got about 25% correctly classified. I had 2 hidden layers. I still don't understand what is wrong with neural networks. I hope to have some help. Thanks

Does ordering of alternatives matter for speed/choosing between alternatives? Yes, it does. Alternative groups are analyzed from left to right, and that happens at each position in the input string. Thus, putting the most common matches at the start is already a boost. When speaking about unanchored alternation lists in NFA regex (as in Python), it is important that alternatives that can match at the same location should be ordered in such a way that the longest comes first because otherwise a shorter alternative will always "win", and you may end up with xxxone when matching with some|someone -> xxx wanting to get xxx from someone.

If I put the most common matches at the front will that speed matching (or is it undefined) although typically exclusive, I sometimes have default cases: 'ax*|a(0-9)|', ie 'a', but I want a greedy match if possible. is it sufficient to reorder 'a(0-9)|ax*' or is this not guaranteed by the specification?

If you want the service itself to run on dedicated hardware within the network and have the webserver itself hosted on the DMZ you'll have to use a proxy. You can use Nginx (for instance) to forward the port in which you're exposing the webserver to the port opened by flask on the dedicated machine. You'll have to configure your firewall to forward that port so that it's accessible to the machine in the DMZ. I'd provide the configuration for your firewall and Nginx but it really depends on the parameters of your network and the service you want to run.

I have written a python library and a web service using flask to expose functions from that library. The library should run on computer A (to do its processing). In our IT setup, web servers will run on a DMZ (computer B). This being the case, if the flask web service directly imports the library and runs a function, it would be running on the DMZ, rather than the intended computer? How do I design the program such that the library executes on the intended hardware, but the web service is hosted by the webserver on the DMZ?

You should probably use cron if two conditions are met; It is available on all platforms your code needs to run on. Starting a script on a set time is sufficient for your needs. Mirroring these are two reasons to build your own solution: Your program needs to be portable across many operating systems, including those that don't have cron available. (like ms-windows) You need to schedule things in a way other than on a set start time. E.g. on a set interval, or if some other condition it met.

If you want to run your python script, let's say every day at 6 pm, is it better to go with a crontab entry or with a Advanced Python Scheduler solution regarding to power, memory, cpu ... consumption? In my eyes doing a crone job is therefore better, because I do not see the advantage of permanently running an Advanced Python Scheduler.

let the exception happen organically. It's up to the caller to decide what to do, so give the caller the information it needs - the exception - and let it decide. Passing return codes just loses information, and is error-prone to boot.

If I have a function that reads a file and returns a list of values, but the file doesn't exist, or have read permissions set for the process, or any other kind of exception, is it better to: let the exception happen organically Try/catch the exception and print the error as a string, and return -1 or some other failure int Try/catch the exception and print nothing, but return -1 Try/catch the exception and return the empty list (which is misleading) Something else In this case we are speaking of Python if it matters.

Should a function that normally returns list return a negative int on an exception?

The answer is not really Python specific. A general rule about exceptions is that you should only catch them in the context where something can be done to recover from it: e.g. try again every 10 sec up to 3 times, where it makes sense, or ask the user what they want to do: retry, abort? If the function catching the exception cannot recover sensibly, it is better to let the exception "bubble up". Sometimes, if the context catching the exception can add additional useful information, you can catch the exception, add meaningful information and re-throw a different, more meaningful exception. It really depends on what you are trying to do. Note that returning an invalid value is a different paradigm of error handling and it makes sense in some situations, but in general, a failure like you describe is better handled through exceptions.

If you can guarantee that the function will always be able to completely deal correctly with the exception then handle the exception in the function itself and return None on failure, since an empty list may be a valid return, and None is more Pythonic than an integer return code. However, it's highly probably that you can't make such a guarantee, so you should allow the exception to bubble up to the caller. Or you may compromise by catching the exception, perform some analysis on it (possibly printing a warning message) and then re-raise the exception, or raise a modified version of it with extra error / warning information attached. This is in accordance with the ancient programmer proverb: Never test for an error condition that you don't know how to handle. :)

It is not possible to call python functions directly from JavaScript callbacks. The JS callback code is executing in the browser, which is not the same process as a python interpreter. If you want to have user interactions, or tools, or callbacks that trigger real, actual python functions, you will have to use the Bokeh server (this is in fact what it is designed to do).

How would you be able to create multiple screens using Pygame and events performed by the user? For example, if I had a menu screen with 2 buttons ('Start' and 'Exit') and the user clicked on 'Start', a new screen would appear in the same window with whatever is next in the game. From that screen, a user could click on another button and move on to another screen/ return to the menu, etc.

What I did for this was have a literal main loop that checks to see what "Screen" the player wants to go to. Like if they press the exit button, it returns where to go next. The main loop then runs a the new script for the new screen.

If you want to run your code on the second GPU,it assumes that your machine has two GPUs, You can do the following trick. open Terminal open tmux by typing tmux (you can install it by sudo apt-get install tmux) run this line of code in tmux: CUDA_VISIBLE_DEVICES=1 python YourScript.py Note: By default, tensorflow uses the first GPU, so with above trick, you can run your another code on the second GPU, separately. Hope it would be helpful!!

You need to start the interpreter first with C-c C-p (run-python). Then you can C-c C-c (python-shell-send-buffer) to send the entire buffer to the python process or even C-c C-r (python-sheel-send-region) to only send the selected region to the python process. See more keybindings for your current buffer with C-h m (describe-mode).

You would need to provide some more information about what kind of interface your web app exposes. Does it only handle normal HTTP1 requests or does it have a web socket or HTTP2 type interface? If it has only HTTP1 requests that it can handle then you just need to make multiple requests or try and do long polling. Otherwise you need to connect with a web socket and stream the data over a normal socket connection.

You have two main options: You can have the WebJobs write the values to a database or to Azure Storage (e.g. a queue), and have the Web App read them from there. Or if the WebJob and App are in the same Web App, you can use the file system. e.g. have the WebJob write things into %home%\data\SomeFolderYouChoose, and have the Web App read from the same place.

If you don't want to copy the binaries you built into a shared location for system-wide use, you should not make install at all. If the build was successful, it will have produced binaries you can run. You may need to set up an environment for making them use local run-time files instead of the system-wide ones, but this is a common enough requirement for developers that it will often be documented in a README or similar (though as always when dealing with development sources, be prepared that it might not be as meticulously kept up to date as end-user documentation in a released version).

I just downloaded Python sources, unpacked them to /usr/local/src/Python-3.5.1/, run ./configure and make there. Now, according to documentation, I should run make install. But I don't want to install it somewhere in common system folders, create any links, change or add environment variables, doing anything outside this folder. In other words, I want it to be portable. How do I do it? Will /usr/local/src/Python-3.5.1/python get-pip.py install Pip to /usr/local/src/Python-3.5.1/Lib/site-packages/? Will /usr/local/src/Python-3.5.1/python work properly? make altinstall, as I understand, still creates links what is not desired. Is it correct that it creates symbolic links as well but simply doesn't touch /usr/bin/python and man? Probably, I should do ./configure prefix=some/private/path and just make and make install but I still wonder if it's possible to use Python make install.

Instead of running two instances on my pi I opted to make what is essentially a transistor switchboard (on a breadboard). I call each send command from a script which first runs another script that turns on one of three GPIOs, activating one of three transistors, and thus exposing one of three IR transmitters to receive signal from the single LIRC gpio. This actually works very well, and I was able to put this together in less time than it takes to read the tutorials on multiple instances and drivers. I needed this ability because I have multiple components which are of the same make and therefore receive some of the same codes such as power. If each device didn't have it's own transmitter I wouldn't be able to control one device without the other non intended device also responding to the command.

So you want to note down how many times each coordinate was visited. You can use a dictionary. A dictionary is a container which holds a particular item for every particular key. Its denoted by curly braces. Let the dictionary be d. d = {} To set an item, d[(x, y)] = 1 Here (x,y) is a tuple. You are confused between what tuples and dictionaries are. You'll do this for the first time. For the next time you'll have to increase it by one which you can do by: d[(x, y)] += 1

I solved the problem by changing the task type from a command task to a script task. My understanding is that not all tasks are run in the sequence as they were defined in the job. If this is not the case, then it might be a bug in Bamboo.

I have setup an Atlassian Bamboo deploy plan. One of its steps is to run a command to run automated UI tests written in Selenium for Python. This runs on a headless Centos 6 server. I had to install the X-server to simulate the existence of a display I made the following commands run in the system boot so that the X-server is always started when the machine starts Xvfb :1 -screen 1600x900x16 export DISPLAY=:1 The command task in the deployment plan simply invokes the following /usr/local/bin/python3.5 .py The funny thing is that when I run that directly from the command line it works perfect the the UI unit tests work. They start firefox and start dealing with the site. On the other hand, when this is done via the deployment command I keep getting the error "The browser appears to have exited " 17-Apr-2016 14:18:23 selenium.common.exceptions.WebDriverException: Message: The browser appears to have exited before we could connect. If you specified a log_file in the FirefoxBinary constructor, check it for details" As if it still does not sense that there is a display. I even added a task in the deployment job to run X-server again but it came back with error that the server is already running. This is done on Bamboo version 5.10.3 build 51020. So, any ideas why it would fail within the deployment job? Thanks,

As with most supervised learning algorithms, Random Forest Classifiers do not use a similarity measure, they work directly on the feature supplied to them. So decision trees are built based on the terms in your tf-idf vectors. If you want to use similarity then you will have to compute a similarity matrix for your documents and use this as your features.

I am doing some work in document classification with scikit-learn. For this purpose, I represent my documents in a tf-idf matrix and feed a Random Forest classifier with this information, works perfectly well. I was just wondering which similarity measure is used by the classifier (cosine, euclidean, etc.) and how I can change it. Haven't found any parameters or informatin in the documentation. Thanks in advance!

If you delete a file which is opened in some processes, it's marked as deleted, but the content remains on disk, so that all processes still can read it. Once all processes close corresponding descriptors (or simply finish), the space will be reclaimed.

I was writing a huge file output.txt (around 10GB) on a server thorugh a python script using the f.write(row) command but because the process was too long I decided to interrupt the program using kill -9 pid The problem is that this space is still used on the server when I check with the command df -h How can I empty the disk occupied by this buffer that was trying to write the file? the file output.txt was empty (0 Byte) when I killed the script, but I still deleted it anyway using rm output.txt but the space in the disk doesn't become free, I still have 10 GB wasted..

Burlap and Hessian are 2 different (but related) RPC protocols, with Burlap being XML based and Hessian being binary. They're both also pretty ancient, so if you have an opportunity to use something else, I'd highly recommend it. If not, then you're going to have to find a Burlap lib for Python. Since it seems that a Burlap lib for Python simply doesn't exist (at least anymore), your best choice is probably to make a small Java proxy that communicates with a more recent protocol with the Python side and in Burlap with the Java server.

I'm trying to connect a burlap java server with a python client but I can't find any detail whatsoever regarding how to use burlap with python or if it even is implemented for python. Any ideas? Can I build burlap python clients? Any resources? Would using a hessian python client work with a java burlap server?
