When it comes to responsiveness, make sure your python code is optimised. That means doing things like not loading Screens or other widgets until you need them (or even doing it in the background as much as possible). For speeding up python itself, the main supported method is cython. python-for-android does not support pypy. kivy can be a little slower and bigger than most android applications because it includes python and the interpreter. A basic Kivy-using APK is about 7MB. And the delay from starting the interpreter manifests largely during the startup of the application, which can take a few seconds, especially on older devices.

I am wondering what options I have to speed up kivy after I package it. I was looking into cython and pypy because those should speed up python. Also, I was reading that kivy can be a little slower and bigger than most android applications because it includes python and the interpreter. I usually just search around forever until i find an answer but it can be hard to find things about kivy. Can anyone with experience recommend something to get better speeds out of this framework? I'm dealing with a lot of code so it could be cumbersome testing a lot of this stuff out. edit: 132137 asked Nov 24 '17 at 19:13 I have a lot of this application packaged now. I wouldn't so much worry about cython until you are packaging it. I would also try to package the application incrementally to make sure everything works. More than anything, I was just really worried about how things would go when I started packaging it. I should have started earlier. The size hasn't been too much of an issue. I would try and write it on ubuntu or a linux distribution(buildozer doesn't work with windows) and not everything will run the same cross all platforms(I had some issues with some of the modules I was working with). I love kivy this is like an eli5 thing I wish I'd known at the time. After messing around with it some I got it down to 16mb. So I'm really happy with the framework. I guess i didn't need to include the buildozer folder in the build. I'm new to programming but I'm pretty happy with how everything turned out.

What are my options to speed up and reduce the size of my kivy android application

Can someone example to me how CSRF works in the cluster setup? I have a kubernetes cluster hosting a django website, and I'm having some occasional issues with 403 errors. I have multiple instances of the site load balanced in kubernetes. How does CSRF work when a POST is sent from 1 instance and handled by another? Does CSRF site work if the docker images are updated during the time the form is being filled out? Thanks!

Can someone example to me how CSRF works in the cluster setup? Exactly the same way it usually ought not to (CSRF is Cross Site Request Forgery, i.e. the attack). To protect against it, you hand out secret tokens to your clients which they must include with subsequent requests. Your backend must validate that the tokens are valid, applicable and were, in fact, issued by a trusted source. There's a few ways to do that bit: You can use MACs for that (in which case you have something pretty close to JSON WebTokens). You can save your tokens to some trusted store and query that store on subsequent requests. That is pretty much all there is to it. Since your CSRF protection emerges from the combination of choices you made above, how to make it work in a distributed setup also depends on the specific implementation of the CSRF protection scheme. Going by the Django docs, the default way to do it uses a 'secret' which is reset every time a user logs in. That means if hitting a different server for two subsequent requests triggers a new log in, all old CSRF tokens are effectively invalidated. So based on that: You need to adapt your Django project to make sure different instances can resume working with the same session, and a re-login is not triggered All your Django instances need to be able to access the same per log-in secret, so that any one of them can validate a CSRF token issued by any other.

I downloaded Visual Studio Code the other day and I decided to use it with pylint. For some odd reason I couldn't set the python interpreter to python 3 from the palette (Shift + Ctrl + P) but I set the path to it from the settings and it seems to have done the job. However, pylint underlines almost everything. All of my imports are underlined with the error message: [pylint] E0401:Unable to import 'my.import' I read a couple of threads on this topic and the main suggestions are to set the correct python path and path to pylint, which I have done with 0 success. I tried removing it pip3 remove pylint and reinstalling it, however, it still did not fix my issue.

So I've been working on a python file in Idle 3.5 (64 bit) and this morning I went to open it and it is completely blank in Idle. When I opened it with Notepad++ it was just a long line that said NULL. In the directory it still says the file is 19KB. What gives? I have a backed up version but I'm not sure why this happened.

Well you can use execfile() or os.system() to solve your problem. But I think, the correct way to tackle your problem is to import the file in your current script and call the imported file's functions or main function directly from your script.

I have a shortcut which runs python3 in a terminal window. I would like to add some import commands to a python script which is to be run when python starts. How can I do this? eg; I have xfce4-terminal -e python3 which starts a graphical terminal session with python3 running. I want to add something to this to make python3 execute a script, however I do not want python to exit at the end of the script, which is the default behaviour if a filename is given immediatly following the python3 command.

If I define for example tkinter.Button widget with parameters (width=10, height=1)(in characters) and then I want to retrieve it's size in pixels, how do I do it? EDIT: I tried widget.winfo_height() and widget.geometry(), but all these functions return height defined in number of characters. I think it would be possible to create the same widget in a frame and then write frame.winfo_height() which would return size in pixels, but this is not so elegant solution.

See /usr/lib/gimp/2.0/interpreters/pygimp.interp (or wherever this is in your Gimp installation directory). You can tweak this to use another Python instance (but it still has to be 2.7.x). On the other hand Gimp's own Python interpreter is the standard cpython, you can use it directly in the command line and can likely tweak pip to install modules for it (or add the modules installed on the other instance to it).

I am developing a custom GIMP plugin on Mac OS X. For programming reasons, I need to use some python modules that I have installed in system's default python environment (such as OpenCV, MoviePy, and some others), but I am unable to import them on the Python-Fu console because it uses the GIMP's app built-in python environment. My question is. Is there a way to tell GIMP to use another python interpreter? I've searched on GIMP preferences but I haven't found anything such as Python-Fu path or something similar. GIMP's Python interpreter is found here on my system: /Applications/GIMP.app/Contents/MacOS/python The interpreter that I want GIMP to use is found here on my system: /usr/bin/python Thanks!

When it says "Python runtime," it just means the Python interpreter in a binary format and its local configuration of package dependencies. Your interpretation is correct.

I am starting the Docker tutorial with the Python app and would like to know what is the meaning of "Python runtime" in this context: In the past, if you were to start writing a Python app, your first order of business was to install a Python runtime onto your machine. But, that creates a situation where the environment on your machine has to be just so in order for your app to run as expected; ditto for the server that runs your app. With Docker, you can just grab a portable Python runtime as an image, no installation necessary. Then, your build can include the base Python image right alongside your app code, ensuring that your app, its dependencies, and the runtime, all travel together. So I guess what it mean is the "Python runtime" is like the configuration of your local Python.

What does the Docker tutorial mean by "grab a portable Python runtime as an image"?

Surprisingly, I found a relatively ok solution using an optimizer from for a deep learning framework, Tensorflow, using basic gradient descent (actually RMSProp, gradient descent with momentum) after I changed the cost function to include the inequality constraint and the bounding constraints as penalties (I suppose this is same as lagrange method). It trains super fast and converges quickly with proper lambda parameters on the constraint penalties. I didn't even have to rewrite the jacobians as TF takes care of that without much speed impact apparently. Before that, I managed to get NLOPT to work and it is much faster than scipy/SLSQP but still slow on higher dimensions. Also NLOPT/AUGLANG is super fast but converges poorly. This said, at 20k variables, it is stillslow. Partly due to memory swapping and the cost function being at least O(n^2) from the pair-wise euclidean distance (I use (x-x.t)^2+(y-y.t)^2 with broadcasting). So still not optimal.

I have a non-lenear optimization problem with a constraint and upper/lower bounds, so with scipy I have to use SLSQP. The problem is clearly not convex. I got the jacobian fo both the objective and constraint functions to work correctly (results are good/fast up to 300 input vector). All functions are vectorized and tuned to run very fast. The problem is that using 1000+ input vector takes ages though I can see the minimizer is not calling my functions a lot (objective/constraint/gradients) and seems to spend most of its processing time internally. I read somewhere perf of SLSQP is O(n^3). Is there a better/faster SLSQP implementation or another method for this type of problem for python ? I tried nlopt and somehow returns wrong results given the exact same functions I use in scipy (with a wrapper to adapt to its method signature). I also failed to use ipopt with pyipopt package, cannot get working ipopt binaries to work with the python wrapper. UPDATE: if it helps, my input variable is basically a vector of (x,y) tuples or points in 2D surface representing coordinates. With 1000 points, I end up with a 2000 dim input vector. The function I want to optimize calculates optimum position of the points between each other taking into consideration their relationships and other constraints. So the problem is not sparse. Thanks...

scipy.optimize.minimize('SLSQP') too slow when given 2000 dim variable

I'm using python pytest to run my unit tests. My project folders are: Main - contains data file: A.txt Main\Tests - the folder from which I run pytest Main\Tests\A_test - folder that contains a test file The test in A_test folder uses the file A.txt (that is in Main folder). My problem is that when I run py.test the test fails because it can't find A.txt. I found out that it is because pytest uses the path Main\Test when running the test instead of changing the path to Main\Tests\A_test (I'm using relative path when opening A.txt inside the test file) My question: is there a way to make pytest change directory to the folder of the test it executes for each test? so that relative paths inside the tests will still work? Is there some other generic way to solve it? (I don't want to change everything to absolute paths or something like this, also this is an example, in real life I have several hundreds tests). Thank you, Noam

I ended up going with my proposed answer: define those functions in utils.py with the data as explicit parameters, and then use functools.partial before generating the equations to make them implicit and with that codebase having been in production for over a year, it seems reasonable enough to me.

My main function loads a largish dataframe from a csv supplied by the user (along with several other data objects), and then instantiates an object that forms a bunch of equations as part of a mathematical programming problem. Many of the equations' components are returned by calls to about 5 helper functions that I define in a utils file (most importantly, outside of the class that stores the optimization problem). These helper functions make reference to the data loaded in main, but I want their calls to show up in the equations as parameterized only by a time index t (not by the dataframe), for readability. Is the best way to accomplish this to define those functions in utils.py with the data as explicit parameters, and then use functools.partial before generating the equations to make them implicit? This seems like a verbose approach to me, but the other options seem worse: to define the helper functions inside of main, or to give up on the idea of a main function loading the data, which basically means giving up on having a main function. And possibly having confusing circular imports.

i know this answer is a little late, but to get permissions you have to specify them before the build. E.g buildozer uses a buildozer.spec. In this file you can specify the permissions you need.

I found that kivy is very nice framework to build cross platform application and I am very interested in kivy just to do android application as I think is easy and comfortable in kivy. After trying few examples, I am interested to know how should handle android run time permission for the kivy app. Actually I had searched on google, but no single working example out there. Should I go back to android / java or it possible with kivy and some other python libs.

python-for-android doesn't have any code for handling runtime permissions. I expect to look at it sooner rather than later, but there's no ETA for it. You can probably add the code for it yourself if you're interested and know how. If you'd like to try it, such contributions would be very welcome.

I found that kivy is very nice framework to build cross platform application and I am very interested in kivy just to do android application as I think is easy and comfortable in kivy. After trying few examples, I am interested to know how should handle android run time permission for the kivy app. Actually I had searched on google, but no single working example out there. Should I go back to android / java or it possible with kivy and some other python libs.

For this very case I simply deleted the folder on local, committed the changes, and then added back the files as I wanted them to be. By the way I would love to know a more general solution, to use when the number of files or folders is too high to handle them individually.

I uploaded a Jupyter notebook on github, since then I worked on it locally and then committed the changes. Now I have a .ipynb_checkpoints folder which does not appear on the local repo, and I would like to remove it from the online repo. If I check with git status, or if I try to commit, it says that everything is up-to-date. How can it be done?

Go to File > Settings > Project > Project Interpreter (it should take you there automatically as soon as you open Settings) and select the version you want to use from the drop-menu. If it is not there, try restarting PyCharm (if it was active whilst the Python 3 installation) - else, it probably means you didn't install Python 3 properly.

I'm a complete newbie trying to use pycharm with python but my interpretor shows a version of 2.7 when i have installed 3.6. Totally confused and need help! On pycharm I do the following steps: Preferences > Python Console > Python Interpretor I only see Python 2.7.8 (/Library/Framework/....) and beneath this I see options beginning with (/Library/Framework.... ) <-- some of these end in bin/python3.6 I am not sure how to configure Pycharm to use the new version of Python. Being a complete newbie I am really confused as to what to do? and whether changing this makes any difference. Any help would be much appreciated. Thanks!

Yes, you can do that by going to Preferences > Editor > Code Introspection/Analysis > Analysis Can I "smart rename" a variable like in other IDEs? Not right now, but we're trying to implement this feature for Spyder 4 (our next major release). Can I list all occurances of a variable like in other IDEs? No, but it's also planned for Spyder 4.

I have some questions about spyder 3.2.4 ide for python: The "sidebar" (to the right of the main code-window) which marks all lines with warnings, all lines with todo etc with a small colored marker. Can I set these colors? Can I disable which ones to show? Can I "smart rename" a variable like in other IDEs? I mean not just text replace, but actually make sure i just rename the selected variable (all occurances and nothing but it) and not just text matching a string i type in like i would in "word". Can I list all occurances of a variable like in other IDEs? Lets say I have a list called "combinedAreas" and want to list all the uses of that variable, preferably also being ablo to click a line and jump to that line. Thanks!

Is it possible to start the index from n in a pandas dataframe? I have some datasets saved as csv files, and would like to add the column index with the row number starting from where the last row number ended in the previous file. For example, for the first file I'm using the following code which works fine, so I got an output csv file with rows starting at 1 to 1048574, as expected: yellow_jan['index'] = range(1, len(yellow_jan) + 1) I would like to do same for the yellow_feb file, but starting the row index at 1048575 and so on. Appreciate any help!

What I know (and I really don't know much) is to keep your frontend separate from your backend. You can create the frontend React components in React. You also create API routes to your backend using e.g. python, flask, ... (firebase is a good option). Then you make HTTP requests from your frontend to your backend API to connect them together.

I would like to use python as part of a react-native project which handles heavy algorithms. However, as many have suggested, it is not recommended to do that, but simply create an API for the python. Now firstly, I'm confused by the term "create an API", what does that mean? Is it to use something like firebase that deals with backend, and then simply use firebase api?

I currently have a scrollbar and a canvas on the same hierarchical level. In the canvas, there is a frame created using the canvas' create_window method. I have a binding that is called when the canvas is configured that will resize the scrollregion to fit bbox("all"). It works, but ONLY when the entire window is resized (e.g. If I add more widgets to the canvas that are now not in its visible region, I have to resize the window to be able to change the canvas' scrollregion). Ideally, the scrollregion should change as soon as the new widget is added to a nonvisible location of the canvas (e.g. it's off the screen). What am I currently doing incorrectly? Any advice is appreciated!

One way for ensuring this would be by generating a session id from server. You would need to generate a unique session id every time a user logs in and store it in some database against that user. Apart from this you would need to authenticate user every time an endpoint call, which requires user to be logged in, is made. And of course discard the session id on logout. This way whenever a user logs in the old session id is discarded and the previous session no more remains valid.

The hierarchy governing the inheritance of font style is knowledge that belongs to the ill-documented black arts of PowerPoint. I don't know of a place where it's clearly described. If I needed to learn it, I would start with a Google search on "powerpoint style hierarchy" to gather candidate participants and then settle in for a long period of experimentation. The candidates I can think of are, roughly in order of precedence: formatting directly applied at the run level default run formatting applied at the paragraph level (this doesn't always take effect) formatting inherited from a placeholder, if the shape was originally a placeholder. A theme related to the slide, its slide layout, or its slide master. A table style Presentation-default formatting. I would devote a generous period to getting anything I could from Google, form a set of hypotheses, then set up experiments to prove or disprove those hypotheses. Note the challenge is made more complex by the conditions involved, such as "is in a table" and "is a placeholder", etc.

Python 3 is known to require more memory than Python 2.7 in many domains: strings are unicode so they use twice as much memory than Python 2 byte strings python 3 int type is equivalent of Python 2 long type so again requires more memory Some improvement may have occur in other domains, but I would not hope that passing from Python 2 to Python 3 could solve any out of memory issue. Increasing physical memory should be a much more reliable way.

The DBSCAN paper suggests to choose minPts based on the dimensionality, and eps based on the elbow in the k-distance graph. In the more recent publication Schubert, E., Sander, J., Ester, M., Kriegel, H. P., & Xu, X. (2017). DBSCAN Revisited, Revisited: Why and How You Should (Still) Use DBSCAN. ACM Transactions on Database Systems (TODS), 42(3), 19. the authors suggest to use a larger minpts for large and noisy data sets, and to adjust epsilon depending on whether you get too large clusters (decrease epsilon) or too much noise (increase epsilon). Clustering requires iterations. That paper was an interesting read, because it shows what can go wrong if you don't look at your data. People are too obsesses with performance metrics, and forget to look at the actual data.

You have to create some sort of communication channel between the javascript and python code. This could be anything, SOAP, HTTP, RPC, any number of and flavor of message queue. If nothing like that is in place, it's quite the long way around. A complex application might warrant you doing this, think micro services communicating across some sort of service bus. It's a sound strategy and perhaps that's why your client is asking for it. You already have Firebase, though! Firebase is a real-time database that already has many of the characteristics of a queue. The simplest and most idiomatic thing to do would be to let the python code be notified of changes by Firebase: Firebase as service bus is a nice strategy too!

I have JS running and essentially getting user entries from my HTML session storage and pushing these to a DB. I also need to use a HTTP request to pass a json object containing the entries to a python file hosted somewhere else. Does anyone have any idea of documentation I could look at, or perhaps how to get JSON objects from JS to Python. My client does not want me to grab the variables directly from the DB.

How do you pass variables using a HTTP post from a JS file/function to a separate python file/function hosted somewhere else?

Since you don't need it to be trainable, a lambda function will also do. Or you can keep the custom layer as you have it, and set trainable to False. The weights will never be updated for this layer, and whatever you do here will forward propagate to the next layer in the model and as mentioned in the comments, backprop will impact the other layers with weights. So, definitely your model will learn something. I personally recommend using a custom layer, if you decide later to add some learning to this layer and check your results. You cannot do this in a Lambda function. If you add one (kernel), you will have to use in the 'call' method. Your model will throw an error during training otherwise.

There is other threads on this but basically this is the rules I use: You should definately remote migrations files using Git. Never run makemigrations on production environment always in developpment. Now, let's say you made a change on one of your models (in developpment I hope), you will run a normal makemigrations. Then, run migrate (still in dev) in order to test everything. When you're ready, you will commit and push the created files and pull in prod to then run migrate to update database schema. This will assure good versionning of your migrations files. Also, it will greatly help you in the long run, because running makemigrations in produciton and in dev simultaneously will just cause more conflicts on migrations files which can be a pain.

array=[1,2,3] is a list, not an array. It is dynamically allocated (resizes automatically), and you do not have to free up memory. The same applies to arrays from the array module in the standard library, and arrays from the numpy library. As a rule, python handles memory allocation and memory freeing for all its objects; to, maybe, the exception of some objects created using cython, or directly calling c modules.

When using large arrays, does python allocate memory as default, unlike C for example? More specifically, when using the command array=[1,2,3], should I worry about freeing this and every other array I create? Looking for answers on the web just confused me more.

The simplest way would be using an async TCP/Unix Socket server in consumer.py. Using HTTP will be an overhead in this case. A producer, TCP/Unix Socket client, will send data to consumer then consumer will respond right away before writing data in disk drive. File IO in consumer are blocking but it will not block producers as stated above.

I have multiple write-heavy Python applications (producer1.py, producer2.py, ...) and I'd like to implement an asynchronous, non-blocking writer (consumer.py) as a separate process, so that the producers are not blocked by disk access or contention. To make this more easily optimizable, assume I just need to expose a logging call that passes a fixed length string from a producer to the writer, and the written file does not need to be sorted by call time. And the target platform can be Linux-only. How should I implement this with minimal latency penalty on the calling thread? This seems like an ideal setup for multiple lock-free SPSC queues but I couldn't find any Python implementations. Edit 1 I could implement a circular buffer as a memory-mapped file on /dev/shm, but I'm not sure if I'll have atomic CAS in Python?

There is no tool needed. Since yyou did not elaborate on your actual use case too much, I can only give a generic answer. You control both RPC server & client + we do NOT talk about stored data In that case you need only to replace the transports on both ends and you're pretty much done. All other cases You will need two pieces a piece of code that deserializes old data stored with "compact" a piece of code that deserializes these data using "binary" Both cases are not really hard to implement technically.

In a project, I'm implementing using Django framework, I have two applications: Application responsible for REST API, containing production models.py file. Application responsible for Web client, that uses REST API's models. Both of them contain vast static files and hierarchy of additional source code, that is why it came to my mind to split this responsibilities into two apps, rather than different views.py and urls.py files inside of one application. Because application responsible for Web relies entirely on REST API's models is it a good practice to delete models.py file from this application entirely?

If you have unique date or DaysToReception, you can actually use Map/HashMap where the key will be the date or DaysToReception and the values will be other information which you can store using a list or any other appropriate data structure. This will definitely improve the efficiency. As you pointed out that "number of rows I search the value below depends on the value "DaysToReception", I believe "DaysToReception" will not be unique. In that case, the key to your Map will be the date.

date is a method of datetime. Whenever you want the date you need to invoke (or call) that method - and the way to do it is with parenthesis. When you don't use parenthesis what you access is the function itself as an object.

I'm currently working with some people to develop an application that will display a "sound library" when the user selects an option on their voip phone. The idea is that the phone system will pass a url with a device id in it, and that will open the django app to the users' library. I was told to remove login/user authentication in order to make the process easier for the user. My question is, is there a way to create a user field and save the model for future retrieval via the url request alone? Do I need to pass the device id to some hidden form first and redirect to the main page, and query the users' objects via the device id? I know there are security concerns but was wondering if it's even possible, any help is appreciated!

I have worked on almost similar problem. Easiest way is to train a Haar-cascade on the vehicles of similar size. You will have to train multiple cascades based on the number of categories. Data for the cascade can be downloaded from any used car selling site using some browser plugin. The negative sets pretty much depend on the context in which this solution will be used. This also brings the issue that, if you plan to do this on a busy street, there are going to be many unforeseen scenarios. For example, pedestrian walking in the FoV. Also, FoV needs to be fixed, especially the distance from which objects are observed. Trail and error is the only way to achieve sweet-spot for the thresholds, if any. Now I am going to suggest something outside the scope of the question you asked. Though this is purely image processing based approach, you can turn the problem on its face, and ask a question 'Why' classification is needed? Depending on the use-case, more often than not, it will be possible to train a deep reinforcement learning agent. It will solve the problem without getting into lot of manual work. Let me know in case of a specific issues.

An ANY query is a perfectly ordinary query that asks for the record type with number 255, which is usually referred to as the ANY type, for fairly obvious reasons. It doesn't matter which tool sends the query (the program dig, or code you write, or something else), it's the same query anyway. There is no guarantee that an ANY query will give the same results as multiple queries for many different types, it's entirely up to the server that generates the responses. Other than for debugging and diagnostics, there is hardly ever a reason to send an ANY query. There are loads of DNS libs for Python. I'm sure someone else can tell you which one is the preferred one these days.

1

0

My general question is how does "dig any" work? In particular, I would like to compare the use of dig to naive sending of multiple equivalent requests (a, txt, mx, ...). Does a single DNS query is sent? Is the use of dig more efficient? Is it guaranteed to get the same results as sending multiple equivalent requests (a, txt, mx, ...)? If they are not equivalent, when should I use each of the methods? And finally, if somebody has Python (prefered Python3) implementation of dig (not by running it using subprocess etc.) - I will be glad to get a reference.

A few things that might help you with debugging speed are: using Python 3.5/3.6. If you're running in linux/macos install the cython extension (you get prompted) Use the latest Pycharm, 2017.3 at this moment. Try to simplify tests. If not possible, just run those you need for the debugging process by creating a special runner in Pycharm and using the -k 'pattern' argument for pytest. Moreover, I don't understand why you're invoking pdb if you're using the Pycharm debugger.

I have a series of tests that are quite complicated. Unfortunately, the builtin Pycharm Debugger is waaay too slow to handle them. I tried making it faster, but any attempts failed, so I have to resort to using pdb. My problem is that the command line that appears if I run my tests with pycharm and come across a pdb breakpoint is quite annoying: It does not support code completion (of course I googled it, but my attempts failed). I can't even press 'up' to get the last command again Most annoyingly: When I already wrote some code in the command line and jump to the beginning of the line to edit it, the cursor automatically jumps to the end of the line. I noticed that it is not the iPython console which I get when I go into pdb debug mode when I don't use pytest. Do you have any idea on how to solve any of these issues? Ideally on how to speed up the Pycharm debugger, or how to get the iPython console also in pytest? Help is much appreciated. Thanks in advance.

I'm in the middle of making a Python script to shutdown, restart, hibernate or put to sleep after a few seconds. I know its subprocess.call(["shutdown", "/s"]) to shutdown, "/r" to restart and "/h" to hibernate. How can you put the computer to sleep using call() on Windows 10?

At the bottom of the MS Code screen is an info bar that lets you know what line, col, text encoding, etc... It also shows the python interpreter you are accessing. If you click on the text for the version of python that is running, it will open a list of available interpreters on your system. If 2.7 is in your path, you can select it.

I have installed on my system several Python interpreters, 2.x and 3.x versions. I am trying to prepare my work environment to allow easily switch between code written in both Python version. It is really important to have as much flexible setting in Visual Studio Code (VSC). The problem is that I have no idea how to set VSC terminal to run code in Python 2.x. Terminal output is needed because it allows to provide user input easily. I've tried instructions provided on VSC page, like manual interpreter's path indication in folder or workspace setting. I reinstalled Python 2.x to ensure PATH variable has been updated. When I run code with CodeRunner extension, it always run it in Python 3.x. Does anyone have similar issue and found how to change Python environment used by this integrated terminal?

In order to have the box removed you need to call a ~destructor function on it, which would remove the image of the box and so on correct? Take advantage of that and create a function that chooses which item to spawn (could be random, up to you) in the position where the box used to be. Then call this function at the end of the destructor. That's how imagine it working.

I'm making a game using Pygame where there are random obstacles on the screen (like boxes). The boxes can be removed by the player when they place a bomb next to it. I have some items that I would like to have randomly appear in place of the box if it is removed. I'm not sure how to go about this logically. Does anyone have any tips? No code is necessary (but helpful), I just want some steps logic-wise to get me started.

Look like your custom model use to much memory and the graphic card cannot support it. You only need to use the --batch option to control the size of memory.

Renaming the GenPy folder should work. It's present at: C:\Users\ _insert_username_ \AppData\Local\Temp\gen_py Renaming it will create a new Gen_py folder and will let you dispatch Excel properly.

You could lowercase or uppercase the username when someone register or login. First get the data from the form: username = login_form.cleaned_data.get('user_username') password = login_form.cleaned_data.get('user_password') After that lowercase the username: username = username.lower() Then authenticate: user = authenticate(username=username, password=password) Remember to lowercase the username in the register form too.

To answer your actual question, threads and coroutines will be equally reliable but coroutines are much easier to reason with and much of the modern existing code you'll find to read or copy will use them. If you want to benefit from multiple cores, much better to use multiprocessing than threads to avoid the trickiness of the GIL.

I have a more open-ended design oriented question for you here. I have background in Python but not in web nor async programming. I am writing an app to save data collect from websockets 24/24, 7/7 with the aim to minmise data loss. My initial thoughts is to use Python 3.6 with asyncio, aiohttp and aiofiles. I don't know whether to use one co-routine per websocket connection or one thread per websocket connection. Performance may not an issue as much as good connection error handling.

For this, you would use the str.split() builtin method. Set x = "[1.0, 2.0, 3.0, 4.0, 5.0]" First of all, get rid of the square brackets around the string: x = x[1:-1] (x is now "1.0, 2.0, 3.0, 4.0, 5.0", a long string) Then, split the string to form a list of strings: x = x.split(',') (x is now ["1.0", "2.0", "3.0", "4.0", "5.0"], a list of strings) Then, convert all of these strings into floats (as I assume you want that): x = [float(i) for i in x] (x is now [1.0, 2.0, 3.0, 4.0, 5.0], a list of floats)

So I'm having an issue where when I read in info from an xml file. The data it reads in is supposed to be a list of numbers but when I read it in, it comes as a string. Is there a way to read xml data as a list or a way to convert a string to a list. Eg I get the data from the xml as say [1.0, 2.0, 3.0, 4.0, 5.0] and if I check the type it says its a string, ie the whole thing is a string including the brackets and the comma. Can't wrap my head around how to convert this back to a list of numbers

Cosine similarity might be useful if you average both word vectors in a bi-gram first. So you want to take the vector for 'his' and 'name', average them into one vector. Then take the vector for 'I' and 'am' and average them into one vector. Finally, calculate cosine similarity for both resulting vectors and it should give you a rough semantic similarity.

1

I'm trying to calculate the semantic similarity between two bi-grams and I need to use fasttext's pre-trained word vectors to accomplish this task. For ex : The b-grams are python lists of two elements: [his, name] and [I, am] They are two tuples and I need to calculate the similarity between these two tuples by any means necessary. I'm hoping there's a score which can give me a good approximation of similarity. For ex - If there are methods which can tell me that [His, name] is more similar to [I, am] than [An, apple]. Right now I only made use of cosine similarity which does include any semantic similarity.

How do I calculate the semantic similarity between two n-grams?

aiohtp is a relative low level library, autoreconnection should be built on top of it. Websocket connection is non-blocking operation in aiohttp. Reliable websocket reconnection is not trivial task. Maybe you need to know what data are received by peer or maybe not -- it depends. In first case you need some high level protocol on top of plain websockets to send acknowledges etc.

I am writing an app listening to websocket connections and making infrequent REST requests. aiohttp seems like a natural choice for this, but I'm flexible. The app is simple but needs to be reliable (gigabytes of data to collect daily while minimising data loss). What is the best way to handle connection loss with aiohttp? I notice that other some other Python libraries have auto reconnect options available. With aiohttp, I could always manually implement this with a loop (start over again as soon as the connection is lost) but I wouldn't know what's the best practice (is it acceptable to keep making reconnection attempts without delay in a loop?).

It is the nature of a non-compiled language like Python that it is impossible to do anything like this without importing. There is simply no way for Python to know what subclasses any class has without executing the files they are defined in.

1

0

The primary problem I'm trying to solve is how to detect all the subclasses of a particular class. The reason I'm unable to use __subclasses__ is that the child classes aren't yet accessible in the context from which I'm attempting to access them. The folder structure I'm working with looks like this: main.py projects/ __init__.py project.py some_project_child.py What I'd like to do is get a list of all subclasses of Project (defined in project.py) from main.py. I'm able to do this by doing: from projects.project import Project from projects.some_project_child import SomeProjectChild Project.__subclasses__ The aspect of this approach I'd like to avoid is having to add an import line every time I add a new project file/class. I realize I can do this by iterating over the files in the directory and import each one's contents but is there a cleaner more pythonic manner of handling this?

I use Enthought Canopy for my python, at first I used "pip install --upgrade pip", it showed a syntax error like yours, then I added a "!" in front of the pip, then it finally worked.

I've just installed python 3.6 which comes with pip However, in Windows command prompt, when I do: 'pip install bs4' it returns 'SyntaxError: invalid syntax' under the install word. Typing 'python' returns the version, which means it is installed correctly. What could be the problem?

pip install returning invalid syntax
