I figured this out, the solution is below: int(hashlib.sha256(block_header + userID).hexdigest(), 16) / float(2**256) You conver the hash into an integer, then divide that integer by 2**256. This gives you a decimal from 0 to 1 that can be compared to a random.random() to get the prize.

I'm building a project that does a giveaway every Monday. There are three prizes, the basic prize, the "lucky" prize, and the jackpot prize. The basic prize is given out 70% of the time, the lucky prize gets given out 25% of the time and the jackpot prize gets rewarded the final 5% of the time. There are multiple people that get prizes each Monday. Each person in the giveaway gets at least the basic prize. Right now I'm just generating a random number and then assigning the prizes to each participant on my local computer. This works, but the participants have to trust that I'm not rigging the giveaway. I want to improve this giveaway by using the blockchain to be the random number generator. The problem is that I don't know how to do this technically. Here is my start to figuring out how to do it: When the giveaway is created, a block height is defined as being the source of randomness. Each participant has a userID. When the specific block number is found, the block hash is catenated to the userID and then hashed. The resulting hash is then "ranged" across the odds defined in the giveaway. The part I can't figure out is how to do the "ranging". I think it might involve the modulo operator, but I'm not sure. If the resulting hash falls into the 5% range, then that user gets the jackpot prize. If the hash falls into the 70% range, then he gets the basic prize, etc.

I had missing conda.exe in Continuum\anaconda3\Scripts folder, so conda command doesn't work. This is not PATH problem. After that I have uninstalled anaconda, rebooted and installed just downloaded last version of anaconda. Installation was without admin rights. After that I still have conda missing in that folder. What can I do? Is where a way to install conda eventually? Is it better to open an issue? Windows 10, anaconda 5.01 PS I have previously installed Anaconda. Which I believe was installed with admin rights to whole users. Can it cause such problem?

In fact - you need to reshape a single data point to have a 3D shape - as keras expects your dataset to have shape (number examples, width, height, channels). If you don't wont to make your image RGB - you can simply leave it with only one channel (and interpret it as greyscale channel).

I am interested in training a Keras CNN and I have some data in the form of 2D matrices (e.g. width x height). I normally represent, or visualize the data like a heatmap, with a colorbar. However, in training the CNN and formatting the data input, I'm wondering if I should keep this matrix as a 2D matrix, or convert it into an RGB image that is essentially a 3D matrix? What is the best practice and some considerations people should take into account?

It also depends on the question for which tool you need(data reduction, otu clustering, making a tree, etc..). These days you see a shift in cluster tools that uses a more dynamic approach instead of a fixed similarity cutoff. Example: DADA2 UNOISE Seekdeep Fixed clustering: CD-HIT uclust vsearch

I am trying to find a new method to cluster sequence data. I implemented my method and got an accuracy rate for it. Now I should compare it with available methods to see whether it works as I expected or not. Is it possible to tell me what are the most famous methods in bioinformatics domain and what are the packages corresponded to those methods in Python? I am an engineer and have no idea about the most accurate methods in this field that I should compare my method to them.

There are many ways to import images for training, you can use Tensorflow but these will be imported as Tensorflow objects, which you won't be able to visualize until you run the session. My favorite tool to import images is skimage.io.imread. The imported images will have the dimension (width, height, channels) Or you can use importing tool from scipy.misc. To resize images, you can use skimage.transform.resize. Before training, you will need to normalize all the images to have the values between 0 and 1. To do that, you simply divide the images by 255. The next step is to one hot encode your labels to be an array of 0s and 1s. Then you can build and train your CNN.

I am new to Tensorflow and to implementing deep learning. I have a dataset of images (images of the same object). I want to train a Neural Network model using python and Tensorflow for object detection. I am trying to import the data to Tensorflow but I am not sure what is the right way to do it. Most of the tutorials available online are using public datasets (i.e. MNIST), which importing is straightforward but not helpful in the case where I need to use my own data. Is there a procedure or tutorial that i can follow?

PCollection is simply a logical node in the execution graph and its contents are not necessarily actually stored anywhere, so this is not possible directly. However, you can ask your pipeline to write the PCollection to a file (e.g. convert elements to strings and use WriteToText with num_shards=1), run the pipeline and wait for it to finish, and then read that file from your main program.

I have a problem with reading in a csv with an id field with mixed dtypes from the original source data, i.e. the id field can be 11, 2R399004, BL327838, 7 etc. but the vast majority of them being 8 characters long. When I read it with multiple versions of pd.read_csv and encoding='iso-8859-1' it always converts the 7 and 11 to 00000007 or the like. I've tried using utf-8 but I get the following error: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc9 in position 40: unexpected end of data I have tried setting the dtype={'field': object} and string and various iterations of latin-1 and the like but it will continually do this. Is there any way to get around this error, without going through every individual file and fixing the dtypes?

What features are you using to detect your books? Are you training a CNN and deploying it with OpenCV? In that case adding rotation image augmentation to your training would make it easy to detect rotated books. If you are using traditional computer vision techniques instead, you can try to use some rotation invariant feature extractors like SURF, however, the results will not be as good as using CNNs which are now the state of the art for this kind of problems.

I have been training OpenCV classifier for recognition of books.The requirement is recognize book from an image. I have used 1000+ images and OpenCV is able to detect books with no rotation. However, when I try to detect books with rotations it does not work properly.So I am wondering if their anyway to detect objects with rotations in images using OpenCV?

Yes, it's possible. To begin with, your host PC mut have a shared folder with your VM (Explained elsewhere). A method I do is to First create a folder myfolder for the (.pdf or .csv) files. Secondly, load the folder by: going to the created myfolder --> right-click on the myfolder --> choose "Open in Terminal". Thirdly, at the terminal it should look like this: myfolder]$. Then I type "jupyter notebook" as such: [username@localhost myfolder]$ jupyter notebook and hit ENTER. The folder should be opened and containing my .pdf or .csv files.

There a few different paths one can follow here. (1) If P(x,y,z) factors as P(x,y,z) = P(x) P(y) P(z) (i.e., x, y, and z are independent) then you can sample each one separately. (2) If P(x,y,z) has a more general factorization, you can reduce the number of variables that need to be sampled to whatever's conditional on the others. E.g. if P(x,y,z) = P(z|x, y) P(y | x) P(x), then you can sample x, y given x, and z given y and x in turn. (3) For some particular distributions, there are known ways to sample. E.g. for multivariate Gaussian, if x is a sample from a mean 0 and identity covariance Gaussian (i.e. just sample each x_i as N(0, 1)), then y = L x + m has mean m and covariance S = L L' where L is the lower-triangular Cholesky decomposition of S, which must be positive definite. (4) For many multivariate distributions, none of the above apply, and a more complicated scheme such as Markov chain Monte Carlo is applied. Maybe if you say more about the problem, more specific advice can be given.

Is there a solution to pass the data to the Python script by avoiding file writing/reading? I can only think of two approaches: You could open a socket for communication between both programs through localhost. The C# program would send data to that socket, and the Python program would read it. Write both programs in Python or C#. The single program would capture data and process it. I've read something about memory mapping, but I do not know if it's a solution. Memory mapping is about loading a file in memory, and once the work on it is finished, write it back at once. Since you have two different processes, I don't think it is applyable here. Hope this helps.

I have a C# (Mono) app that gets data from a sensor and passes it to a Python script for processing. It runs on a Raspberry Pi/Raspbian. The script is started at program initialization and is running in background waiting for data to be passed to it. The data consists of 1000 samples, 32 bit double (in total, 32 kbits). Currently I write the data in a file and pass the file path to the script. I was thinking of speeding up processing time by passing the data directly to the script, avoiding writing the file. However, I see that the number of characters of command line arguments is a limited. Is there a solution to pass the data to the Python script by avoiding file writing/reading? I've read something about memory mapping, but I do not know if it's a solution.

I am new and just start learning flask. In my project, I need all the pages are printed in two languages, say 'LAN_A' and 'LAN_B'. So I need a variant to save it. Now I save it in app.config['language'] = 'LAN_A'/'LAN_B'. When debugging locally, I browse the page by two devices (thus also two IP). In device1, I change the language then I found all the pages in device2 will also be changed(after the setting in device1). It seems understandable since there is only one main.py is running. My question: Is it because my treatment is inappropriate? or future in the real service, we have some method to let each user run one main.py?

As long as you don't change the extension of the image file, the pixel values don't change because they're stored in memory and your display or printer are just the way you want to see the image and often you don't get the same thing because it depends on the technology and different filters applied to you image before they're displayed or printed..

Assume we are reading and loading an image using OpenCV from a specific location on our drive and then we read some pixels values and colors, and lets assume that this is a scanned image. Usually if we open scanned image we will notice some differences between the printed image (before scanning) and the image if we open it and see it on the display screen. The question is: The values of the pixels colors that we get from OpenCV. Are they according to our display screen color space or we get exactly the same colors we have in the scanned image (printed version) ??

The only way I found in grafana 7.1 was to: Open the dashboard and then inspect the panel Open the query tab and click on refresh Use the url and parameters on your own query to the api note: First you need to create an API key in the UI with the proper role and add the bearer to the request headers

Need to extract specific data from grafana dashboard. Grafana is connected to graphite in the backend. Seems there is no API to make calls to grafana directly. Any help? Ex: I need to extract AVG CPU value from graph of so and so server.

How can we extract data from grafana dashboard?

The content-type header is what tells the browser how to display a given file. It doesn't know how to display text/csv, so it has no choice but to treat it as an opaque download. If you want the file to be displayed as plain text, you need to tell the browser that it has content-type text/plain. If you need to tell other clients that the content type is text/csv, you need some way to distinguish clients that understand that content type from those that do not. The best way to do this is with the Accept request header. Clients that understand CSV would send Accept: text/csv in their request, and then the server would respond with content-type text/plain or text/csv depending on whether CSV appears in the accept header. Using the Accept header may require modifications to the client, which may or may not be possible for you. If you can't update the clients to send the Accept header, then you'll have to use a hackier workaround. You can either use a different url (add ?type=plain or ?type=csv) or try to detect browsers based on their user agent.

My server in Python (Tornado) send a csv content on a GET request. I want to specify the content type of the response as "text/csv", but when I do this the file is downlaoded when I send the GET request on my browser. How can I specify the header "Content-type : text/csv" without having making it a downlaodable file but just show the content on my browser ?

You state the the database is blank, if so you're going to have to have at least 1 record in the parent table, where the primary key is defined. After that you can use the parent.primary-key value in your CSV file as a dummy value for your foreign key. That should at least allow you to populate the table. Later on, as your parent table grows you're going to have to write some sort of script to add the correct parent.primary-key value to each record in the CSV file and then import it.

I'm a little new to this, and figuring it out as I go. So far so good, however I have having trouble importing a field that has a foreign key. I have about 10,000 rows in a csv file that I want to add to the database. As you can imagine, entering 10,000 items at a time is too labour intensive. When I try for an import I get this error: ValueError: invalid literal for int() with base 10 This is because (i think) it is trying to match the related model with the id. However the database is empty, so there is no id, and furthermore, the "author" field in my csv (the one with the foreign key) doesn't have an id yet. ( i assume this is created when the record is). Any suggestions? Sorry in advance for the newbie question.

It turns out, after some tinkering, that using the MongoClient argument socketTimeoutMS, if set to something quicker than that observed by AutoReconnect, will supersede AutoReconnect. Contrary to my initial concern, this does not interfere with long running queries as the socket connected just fine. I discovered that after the first NetworkTimeout exception is raised as a result of this setting it can take 10 seconds or so to attempt again. That is solved by also passing the connectTimeoutMS argument to MongoClient with, most likely, the same value as that of socketTimeoutMS. Please post a response here if anyone discovers any caveats to this solution.

I'm using a 3-node MongoDB replica set and connecting to it using Pymongo v3.3.1. In testing the handling of errors like AutoReconnect and ServerSelectionTimeout and such I find that I can't (safely/reliably) control how long it takes to raise an AutoReconnect exception. If I instantiate MongoClient with the argument serverSelectionTimeoutMS set to, for instance, 2000, I do see the ServerSelectionTimeout exceptions return in about 2 seconds. However, when the conditions are just right to trigger an AutoReconnect it always takes at least 20 seconds, sometime closer to 30 seconds! How can I constrain this behavior? I'm shooting for relatively high availability and want to detect network/replica set anomalies and commence my retry logic rather rapidly.

Is there any way to decrease the time it takes for a pymongo.errors.AutoReconnect to occur?

It's true that the AWS CLI uses boto, but the cli is not a thin wrapper, as you might expect. When it comes to copying a tree of S3 data (which includes the multipart chunks behind a single large file), it is quite a lot of logic to make a wrapper that is as thorough and fast, and that does things like seamlessly pick up where a partial download has left off, or efficiently sync down only the changed data on the server. The implementation in the awscli code is more thorough than anything in the Python or Java SDKs, as far as I have seen. I've seen several developers who were too proud to call the CLI from their code, but zero thus far all such attempts I have seen have failed to measure up. Love to see a counter example, though.

I have packages stored in s3 bucket. I need to read metadata file of each package and pass the metadata to program. I used boto3.resource('s3') to read these files in python. The code took few minutes to run. While if I use aws cli sync, it downloads these metafiles much faster than boto. My guess was that if I do not download and just read the meta files, it should be faster. But it isn't the case. Is it safe to say that aws cli is faster than using boto?

Is aws CLI faster than using boto3?

The "without calibration" bit dooms you, sorry. Without knowing the focal length (or, equivalently, the field of view) you cannot "convert" a pixel into a ray. Note that you can sometimes get an approximate calibration directly from the camera - for example, it might write a focal length for its lens into the EXIF header of the captured images.

I got the distance to the object based on the size of the tracked object (A marker) but now I need to convert all of this to a 3D coordinate in the space. I have been reading a lot about this but all of the methods I found require a calibration matrix to achieve this. In my case I don't need a lot of precision but I need this to work with multiple cameras without calibration. Is there a way to achieve what I'm trying to do?

If you're using some sort of micro controller, it may be possible to point a sensor towards that object that's seen through the camera to get the distance. You would most likely have to have a complex algorithm to get multiple cameras to work together to return the distance. If there's no calibration, there would be no way for those cameras to work together, as Francesco said.

I'm trying to match text strings (gene names) in a column from one file to text strings in a column of another, in order to create a subset the second. For simplicity, the first will look more or less like this: hits = ["IL1", "NRC31", "AR", etc.] However, the column of interest in the second df looks like this: 68 NFKBIL1;NFKBIL1;ATP6V1G2;NFKBIL1;NFKBIL1;NFKBI 236 BARHL2 272 ARPC2;ARPC2 324 MARCH5 ... 11302 NFKBIL1;NFKBIL1;ATP6V1G2;NFKBIL1;NFKBIL1;NFKBI 426033 ABC1;IL1;XYZ2 ... 425700 IL17D 426295 RAB3IL1 426474 IL15RA;IL15RA I came up with: df2[df2.UCSC_RefGene_Name.str.contains('|'.join(hits), na=False)] But I need to match the gene IL1 if it falls in the middle of the string (e.g.row 426033 above) but not similar genes (e.g. row 426295 above). How do I use regular expressions to say: "Match the any of the strings in hits when they have ';' or 'a blankspace' at either the beginning or the end of the gene name, but not when they have other letters or numbers on either side (which indicate a different gene with a similar name)? I also need to exclude any rows with NA in dataframe 2. Yes, I know there are regex syntax documents, but there are too many moving parts here for me to make sense of them.

Without more information about your source code and the packages you're using, this is really more of a data science question than a python question. To answer your question, a more than satisfactory method in most circumstances it min-max scaling. Simply normalize each coordinate of your images between 0 and 1. Whether or not that is appropriate for your circumstance depends on what you intend to do next with that data.

More detail about what you are actually doing would be helpful. That is, vague questions can really only get vague answers. Assuming you are doing curve fitting with lmfit's Model class, then once you have your Model and a set of Parameters (say, after a fit has refined them to best match some data), then you can use those to evaluate the Model (with the model.eval() method) for any values of the independent variable (typically called x). That allows on a finer grid or extending past the range of the data you actually used in the fit. Of course, predicting past the end of the data range assumes that the model is valid outside the range of the data. It's hard to know when that assumption is correct, especially when you have no data ;). "It's tough to make predictions, especially about the future."

You want to get a subset using indexes. set is an unordered collection with non-duplicated items. The set's pop method removes a random item from the set.

RASA NLU is the natural language understanding piece, which is used for taking examples of natural language and translating them into "intents." For example: "yes", "yeah", "yep" and "for sure" would all be translated into the "yes" intent. RASA CORE on the other hand is the engine that processes the flow of conversation after the intent of the user has already been determined. RASA CORE can use other natural language translators as well, so while it pairs very nicely with RASA NLU they don't both have to be used together. As an example if you were using both: User says "hey there" to RASA core bot Rasa core bot calls RASA NLU to understand what "hey there" means RASA NLU translates "hey there" into intent = hello (with 85% confidence) Rasa core receives "hello" intent Rasa core runs through it's training examples to guess what it should do when it receives the "hello" intent Rasa core predicts (with 92% confidence) that it should respond with the "utter_hello" template Rasa core responds to user "Hi, I'm your friendly Rasa bot" Hope this helps.

Is there a way that I can instantiate the classes I want to use within the App and keep those classes "Alive" for use by other parts of the Application that live in separate files? Some of these Classes are objects that handle API GET/POST requests and don't have web sockets available for their endpoints.

This is a commonly used pattern when separating Web Servers and App Servers in traditional Web Application setup, keeping the Web Servers in public subnets (Or keeping internet accessible) and the business rules kept in App Servers in the private network. However, it also depends on the complexity of the system to justify the separation having multiple servers. One of the advantages of this approach is you can scale these servers separately.

I have two instances. One is on the Public Subnet & the other is on the Private subnet of AWS. In the private system, I am performing some computation. And the public system is acting as the API endpoint. My total flow idea is like this: When some request comes to the public server, the parameters should be forwarded to the private system, the computation will be done there and the result will be sent back to the public and from there the result will be fed back to the user. In the private system, some python code is running. I did setup Apache-Flask in the private system. So the idea is when some requests are coming, from the public server the parameters will be extracted and another HTTP request will be fired to the private system. Computation will be done there and the response will return which will return to the client system. I have two question, Is this a good approach? Any better way to implement the total scenario?

Basically, no counter is allowed. No iterables (arrays, dictionaries, etc.) allowed either to store insertion. There are two linked lists: one storing odd insertions and even insertions. Each node has the priority, and the object. Is there any pattern you can find? Or is this impossible? Edit: sorry for not mentioning, we need to extract the first one that was inserted.

As of Python 3.3, the function os.replace is available. It should provide cross-platform mv-like semantics. Sadly it fails when trying to move files across file systems. Even though the documentation says, that shutil.move depends on the semantics of os.rename, it also works on Windows, and supports moving files across file-system boundaries. Sadly, I have seen cases where for some reason it still denied overwriting a file, so when possible, os.replace should be safer.

For the purpose of safely updating a file, I am writing an updated version to a temporary file and then try to overwrite the original file with it. In a shell unix script I would use mv FROM TO for this. With python on Linux, the functions os.rename and shutil.move perform an atomic replace operation when the target filename exists. On Windows, they fail. The behavior can be approximated by a sequence of copy, rename and remove operations, but it cannot be guaranteed, that such a self-written replace operation is performed either finished or completely reverted. Is it possible to get a reliable “rename and overwrite” operation on Windows?

No, you do not need to flush the file before closing. Flushing is done automatically by the underlying HDF5 C library when you close the file. As to the point of flushing. File I/O is slow compared to things like memory or cache access. If programs had to wait before data was actually on the disk each time a write was performed, that would slow things down a lot. So the actual writing to disk is buffered by at least the OS, but in many cases by the I/O library being used (e.g., the C standard I/O library). When you ask to write data to a file, it usually just means that the OS has copied your data to its own internal buffer, and will actually put it on the disk when it's convenient to do so. Flushing overrides this buffering, at whatever level the call is made. So calling h5py.File.flush() will flush the HDF5 library buffers, but not necessarily the OS buffers. The point of this is to give the program some control over when data actually leaves a buffer. For example, writing to the standard output is usually line-buffered. But if you really want to see the output before a newline, you can call fflush(stdout). This might make sense if you are piping the standard output of one process into another: that downstream process can start consuming the input right away, without waiting for the OS to decide it's a good time. Another good example is making a call to fork(2). This usually copies the entire address space of a process, which means the I/O buffers as well. That may result in duplicated output, unnecessary copying, etc. Flushing a stream guarantees that the buffer is empty before forking.

In the Python HDF5 library h5py, do I need to flush() a file before I close() it? Or does closing the file already make sure that any data that might still be in the buffers will be written to disk? What exactly is the point of flushing? When would flushing be necessary?

In h5py, do I need to call flush() before I close a file?

I'm seeing a hard to track down error with Google Cloud IoT. I have 2 projects set up with IoT API enabled. I'm using the same "quickstart" instructions to test, by setting up "my-registry" and "my-device". Let's call them projects A and B. I then run both the python and node examples pulled straight from git. The node example runs fine for both projects A and B, validated by pulling using gcloud. However, the python example works for project A, but with project b gets a "on disconnect. 1. out of memory" error. There is never a "connection accepted" message for B, but yes for A. "Out of memory" seems to be a generic error, not really the issue. It could represent a variety of issues in connectivity. Nothing on the server side Anyone encountered this one before? I appreciate any help in resolving or at least trace the eror.

given multi-variable regression, y = Regression is a multi-dimensional separation which can be hard to visualize in ones head since it is not 3D. The better question might be, which are consequential to the output value `y'. Since you have the code to the loadavg in the kernel source, you can use the input parameters.

I can't get my head around how to implement SVR. I understand my 'y' would be predicted value in kWh but what about my X values? Can anyone help?

I want to develop two packages A and B in parallel, and B depends on A. I need to import something from A when running my unit tests for B. So how can I configure things in setup.py so that when I run the unit tests for B, the local directory (in parallel to the one for B) gets added to the modules path and A can be imported? I do not constantly want to install A so that B can depend on it like on an installed package.

Then I installed some modules in PyCharm (Numpy, Pandas, etc), but when I tried installing Tensorflow it didn't install, and I got the error message: Could not find a version that satisfies the requirement TensorFlow (from versions: ) No matching distribution found for TensorFlow. Then I tried installing TensorFlow from the command prompt and I got the same error message. I did however successfully install tflearn. I also installed Python 2.7, but I got the same error message again. I googled the error and tried some of the things which were suggested to other people, but nothing worked (this included installing Flask). How can I install Tensorflow? Thanks.

As of October 2020: Tensorflow only supports the 64-bit version of Python Tensorflow only supports Python 3.5 to 3.8 So, if you're using an out-of-range version of Python (older or newer) or a 32-bit version, then you'll need to use a different version.

(as of Jan 1st, 2021) Any over version 3.9.x there is no support for TensorFlow 2. If you are installing packages via pip with 3.9, you simply get a "package doesn't exist" message. After reverting to the latest 3.8.x. Thought I would drop this here, I will update when 3.9.x is working with Tensorflow 2.x

I solved the same problem with python 3.7 by installing one by one all the packages required Here are the steps: Install the package See the error message: couldn't find a version that satisfies the requirement -- the name of the module required Install the module required. Very often, installation of the required module requires the installation of another module, and another module - a couple of the others and so on. This way I installed more than 30 packages and it helped. Now I have tensorflow of the latest version in Python 3.7 and didn't have to downgrade the kernel.

Plan so far, is to make a copy of the same scripts (folder) a couple of times while renaming each to unique name to distinguish later, then run it using cron scheduler. advise please.

Running the same script multiple times , easier way to manage and report

as per my experience and knowledge, you are almost going towards correct direction. my recommendation is for making backend rest api Django and django rest framework is the best option however for consuming those api you can look for the angular or react both works very well in terms of consuming API.

I am currently developing my first more complex Web Application and want to ask for directions from more experienced Developers. First I want to explain the most important requirements. I want to develop a Web App (no mobile apps or desktop apps) and want to use as much django as possible. Because I am comfortable with the ecosystem right now and don't have that much time to learn something new that is too complex. I am inexperienced in the Javascript World, but I am able to do a little bit of jQuery. The idea is to have one database and many different Frontends that are branded differently and have different users and administrators. So my current approach is to develop a Backend with Django and use Django Rest Framework to give the specific data to the Frontends via REST. Because I have not that much time to learn a Frontend-Framework I wanted to use another Django instance to use as a Frontend, as I really like the Django Template language. This would mean one Django instance one Frontend, where there would be mainly TemplateViews. The Frontends will be served on different subdomains, while the backend exposes the API Endpoints on the top level domain. It is not necessary to have a Single Page App. A Normal Website with mainly the normal request/response-cycle is fine. Do you think this is a possible approach to do things? I am currently thinking about how to use the data in the frontend sites in the best way. As I am familiar with the Django template language I thought about writing a middleware that asks about the user details in every request cycle from the backend. The thought is to use a request.user as normally as possible while getting the data from the backend. Or is ist better to ask these details via jQuery and Ajax Calls and don't use the django template language very much? Maybe there is also a way to make different Frontends for the same database without using REST? Or what would you think about using a database with each frontend, which changes everytime I make a change in the main database in the backend? Although I don't really like this approach due to the possibility of differences in data if I make a mistake. Hopefully this is not to confusing for you. If there are questions I will answer them happily. Maybe I am also totally on the wrong track. Please don't hesitate to point that out, too. I thank you very much in advance for your guiding and wish you a nice day.

Even if you will install gpu version !pip install tensorflow-gpu==1.5.0 it will still fail to import it because of the cuda libraries. Currently I have not found a way to use 1.5 version with GPU. So I would rather use 1.4.1 with gpu than 1.5 without gpu. You can send them a feedback ( Home - Send Feedback ) and hopefully if enough people will send something similar, they will update the new gpu version.

Currently google colaboratory uses tensorflow 1.4.1. I want to upgrade it to 1.5.0 version. Each time when i executed !pip install --upgrade tensorflow command, notebook instance succesfully upgrades the tensorflow version to 1.5.0. But after upgrade operation tensorflow instance only supports "CPU". When i have executed this command it shows nothing : from tensorflow.python.client import device_lib device_lib.list_local_devices() Should there be another way for upgrading tensorflow ? such as upgrading to tensorflow-gpu package ? Also when will notebooks will come with upgraded tensorflows ?

For now I solved it by subclassing my model schema, adding the additional field there, and then - before loading my data through the model schema - validating it through the subclassed schema. If there is a more elegant solution I'd still love to hear it.

I'm trying to build a Marshmallow schema based on a model, but with one additional field. While this seemed to work by declaring the special field by itself and then setting meta.model to my assigned model, I fail to find a solution so that the additional field gets validated (it is marked as required), but does not turn up in the resulting, deserialized object. I tried setting it as excluded and dump_only, but to no avail, either the validation does not take place, or the deserialized object also contains the additional field (which then clashes with my ORM).

For anyone who might ever find himself in the same situation, I have found a workaround that works for me and might even work for you! So, this is actually quite simple, but only works for a specific application. Here, I have a sensor which is read by a javascript script, but I want a python script to handle the sensor's output value. What I did was: import subprocess import os deadly_string = subprocess.getoutput('npm run test') not_so_deadly_string = deadly_string[-6:] print ("value: ", not_so_deadly_string) I captured the output of the terminal with "subprocess.getoutput". The output of the terminal looks something like this: nodejs-qmc5883l@.... ..... Declination angle correction: 1 . . . Azimuth= 300.00 The value "300.00" is what I want, so I cut the last 5 characters of the string and that's it....

I have accomplished running a js file with the following python script: import subprocess subprocess.check_call('npm run test') The file test.js reads sensor data and is only written in javascript because the only available library for this sensor is a NodeJS library. Now, I want the test.js to return those values everytime it is executed within my python script. How do I do that? And it is not possible via this method, are there others? I cannot write this js script in python as the library uses NodeJS. I want to thank everone that tries to help me in advance and if you need more info, simply contact me!

It sounds like you are trying to evaluate pow(a, b) % c. You should be using the 3-argument form, pow(a, b, c), which takes advantage of the fact that a * b mod c == a mod c * b mod c, which means you can reduce subproducts as they are computed while computing a ^ b, rather than having to do all the multiplications first.

I am trying to calculate something like this: a^b mod c, where all three numbers are large. Things I've tried: Python's pow() function is taking hours and has yet to produce a result. (if someone could tell me how it's implemented that would be very helpful!) A right-to-left binary method that I implemented, with O(log e) time, would take about 30~40 hours (don't wanna wait that long). Various recursion methods are producing segmentation faults (after I changed the recursion limits) Any optimizations I could make?

In Windows 10 Anaconda installs itself into a hidden folder called ".anaconda" which is placed in the Users directory under your own profile sub directory. When you first try to use the right-click menue "Open with" it opens up in C:\Program Files so you have to go up one folder and down into Users. You may need to have previously set one of the options in the View Menu of the file manager so that you can see hidden files. You can't do this from the "right-click open with" place, you have to set that in the regular file manager. You will find a file called Spyder.bat a couple of folders down within that, e.g. C:\Users\Your_profile.anaconda\navigator\scripts It will take forever to open each time.

I installed Spyder using Anaconda, and I am able to launch the IDE using the Spyder icon in my start menu (Win10). I wanted to set my preferences to open all .py files with Spyder, so I followed the Spyder start menu button to an executable, pythonw.exe. The problem is that I cannot launch pythonw.exe by clicking it. How does the start menu icon for Spyder, which points to pythonw.exe, launch Spyder, but clicking the executable does not yield the same results? Also, when I double click spyder.exe in Anaconda\Scripts a command prompt opens along with the IDE, which does not happen when I click the start menu icon. Why does this application behave so much differently than any other application I've used before (if this is just how things are in python, I apologize as I'm new!) and is it possible to set Spyder as the default application to open .py files in the same way I can open source files with IDEs in other languages?

When you run the first instance it will use the first Python config file. Then when you run the second instance it will run the newly updated config file. It should all work fine as long as its not running on a localhost port, because it will try to use the same port and wont run. If this is not the case then it should run with the updated config file.

I'm running a simulation (more on this in a sec) and one of the files for this simulation is a python file that contains configuration details. I want to run multiple versions of this simulation, but I don't know if running one simulation, opening another terminal, then editing the python file and running a second simulation will ruin the first simulation. Does python have a concept of "source code" is separate from the actual process? Can I edit the file safely? These simulations take a while. (So, I'm running a gem5 simulation and I need to run multiple versions of the simulation, varying properties of the CPU. Just in case that helps.)

Is it ok to run python file, edit it, then run it in second terminal

I Think the easiest way to do that is using shebang, and it works both linux and windows. For windows you just have to add #!.\venv\Scripts\python.exe at the very first line at your .py script file.

I got a task to make exports of several big tables in DB asynchronous because right now the amount of records is so big that it takes too much time. So I've successfully moved the code of exporting to the Celery task. It exports and saves the file in a folder on a server. But I am not able to get from the task the whole filename, which I could pass to the rest of code and therefore download it after completing the export process because the only thing Celery task can return is only the state of the result of performing the task (done or not yet or failed). I am using Django/Python + Celery + Redis. Thank you for any advice, it already borders me for several days.

When you use defer or only to load an instance, the get_deferred_fields() method returns a list of field names that have not been loaded; you should be able to use this to work out which ones will be saved.

I am using Django 1.11, in one of my models I have added actions when the model is saved. However I don't want these actions to be done when only a part of the model is saved. I know that update_fields=('some_field',) can be used to specify which field must be saved. But, when the object has been fetched in the database using the methods only() or defer() I don't see any information about the fields updated in the save() method, update_fields is empty. Thus my question: How can I get the fields saved by Django when only some fields have been fetched ?

How to know which field is saved when only() has been used in Django?

I have developed few modules in python and I want to import them to rstudio RMarkdown file. However, I am not sure how I can do it. For example, I can't do from code.extract_feat.cluster_blast import fill_df_by_blast as fill_df as I am used to do it in pycharm. Any hint? Thanks.

Try checking if it is in the 'bin' folder. Alternatively, add the the path to numpy in the environment variables.

I want to use numpy in my Jupyter notebook. However, I came across a weird problem. Despite the fact that: I have a numpy installed in my default python3. From Jupyter I've run a command !pip install numpy and !pip3 install numpy. I restarted my notebook multiple times. After running a command import numpy I get a message that package is not found: ImportError: No module named 'numpy' I use python3 kernel of course. Has anyone come across similar problem?

Try the below: pd.read_csv("filepath",encoding='cp1252'). This one should work as it worked for me.

I have been trying to upload a csv file using pandas .read() function. But as you can see from my title this is what I get "'utf-8' codec can't decode byte 0x92 in position 16: invalid start byte" And it's weird because from the same folder I was able to upload a different csv file without problems. Something that might have caused this is that the file was previously xlsx and I manually converted it to cvs? Please Help Python3

I found that it's possible to add an option --deb-systemd FILEPATH which points to which file should be put in systemd for the service and solved my issue.

I'm working on distributing a python package that uses uwsgi and falcon to run an API. To build it as a deb package I am using fpm. After some tinkering I have managed to get my package to include everything I need for my virtualenv, however now I am running into the problem that my service files aren't installing properly and I can't start the service with systemctl I build the package using: fpm -s virtualenv -t deb --prefix /opt/venvs/{project_name} --version {$VERS} --name {project_name} path/to/setup.py path/to/requirements.txt Inside my package I have systemd/{service_name}.service, however the service files aren't in my package when I check the contents with dpkg -c {service_name}.deb | grep service How can I get fpm to build the deb package with the service files correctly? Thanks.

Look at the 502 spec: The HyperText Transfer Protocol 502 Bad Gateway server error response code indicates that the server, while acting as a gateway or proxy, received an invalid response from the upstream server. If your app responds anything while hitting an exception, it's most likely garbage and nginx raises (correctly) the 502, meaning "I won't (as opposed to can't) talk to the backend". If you want 500s, you have to catch any possible underlying exception, wrap it in a valid response and it will be processed by nginx.

I am running a Flask application and using uwsgi socket nginx configuration. This may be a stupid question but the issue I am facing is that whenever there is exception raised in Flask code (non handled exception for example 1/0), my nginx gives 502 instead of 500. I wanted to know if raising the exception is not getting propagated to nginx as 500 from uwsgi unix socket by default or do I need to specify this explicitly? Somewhere I read that for exceptions, Flask doesn't raise 500 error message automatically. Any comments will be helpful. Thanks.
