Description:
I'm using Vscode Studio for python coding, I've installed every extension related to python and I wanna use Jupyter. I'm experiencing no problem with importing packages or running code but when I try to grab the input from the user it throws me an error stating 'StdinNotImplementedError: raw_input was called, but this frontend does not support input requests.' which I don't find using the console.

849 )
850 return self._input_request(str(prompt),
StdinNotImplementedError: raw_input was called, but this frontend does not support input requests.
Steps Taken:
Use the raw_input function instead of input.
Install and uninstall python and jupyter extension.
Checked the version of jupyter notebook --version (5.7.4) and python -m ipykernel --version (7.2.0).
Restarted kernel but encounter the same error.
Observation:
The issue is not replicable when the code is executed with python integrated terminal
Please let me know if there is setting which I'm missing or is this a bug.
Ctrl + Shift + D
Environment -> Python
This creates launch.json file within a .vscode directory in the current directory
Paste the following json:
{
"version": "0.2.0",
"configurations": [

Save the file and open python script in the editor
Start without debugging

While setting up Python Development Environment in Sublime text 3, I wanted Auto formatting on and hence I made the following settings in Preferences > Package settings > Anaconda > Settings User
{
"auto_formatting": true,
"autoformat_ignore":
[
],
"pep8_ignore":
[
"E501"
],
"anaconda_linter_underlines": false,
"anaconda_linter_mark_style": "none",
"display_signatures": false,
"disable_anaconda_completion": true,
"python_interpreter": "/usr/local/bin/python3"
}
The auto_formatting value is set to true in user settings and it is set to false in default settings .
The auto formatting does not work out and gives me Autoformatting failed, buffer not changed error . Also tried changing auto_formatting_timeout = 5 //seconds , but that didn't work out . It would be of great help if someone could help me out .
I had the exact same issue. The problem is the last line is pointing to the wrong path for your python interpreter
Preferences > Package Settings > Anaconda > Settings - User
Delete the last line
"python_interpreter": "/usr/local/bin/python3"
Replace it with
"python_interpreter": "C:\\Users\\YOUR_NAME\\AppData\\Local\\Programs\\Python\\Python38-32\\python.EXE"
IMPORTANT: Your python interpreter path might be different to mine so find out where it is. Remember you need to use TWO backslashes in the path not ONE
Sublime is looking for python in environmental variable when you build it, and it is not able to find it there. You can test it in cmd by typing python and if it opens Microsoft store then here is the fix you can do, it worked for me. Open setting -> search for manage app execution aliases -> turn off "python.exe" and "python3.exe". Now check if you can get python in cmd by typing python, if you do then sublime problem should be fixed. If you want to know why this works follow this stack overflow
I'm running my code using the extension "Code Runner" and would like the output to be displayed word-wrapped. Currently when I run it, it displays the output all in a single line even if it's a long line.
I tried the setting "editor.wordWrap": "on".
This is how the output and editor look like:
Try adding this to your settings:
"[Log]": {
"editor.wordWrap": "on"
}
You can instead use the built-in debugger configuration for Python and set in launch configuration to use the "internalConsole"
{
"name": "run-test-py",
"type": "python",
"request": "launch",
"program": "${workspaceFolder}/myfile.py",
"console": "internalConsole"
},
so that the output appears in the Debug Console panel. The word wrapping for that panel is controlled by the Debug > Console: Word Wrap setting:
Set it to true:
"debug.console.wordWrap": false,
For the Debug Console you can use "debug.console.wordWrap": false,//default:true which was added in June 2019 with issue 72210
I have heard that Dot net core only generates dll file and the only way to run them is using the command
dotnet myapp.dll
I have a chrome extension and i am trying to do some operations . For example, on chrome extension i enter two numbers and then click send button. this triggers the native messaging and a windows executable/dll is called which takes these 2 numbers as stdin and returns the sum as stdout which would be displayed on chrome extension .
Earlier it was an exe file which was working fine. Now i have migrated the code to dotnet core 2.0 . My unit tests work fine but the dll is unable to execute . i dont see any logs as well . my best guess is that the dll is not getting called at all. somehow i have no idea how to check if the app is getting called from chrome extension
{
"name": "myapp",
"description": "myapp",
"path": "C:\\Program Files (x86)\\myapp.dll",
"type": "stdio",
"allowed_origins": [
"chrome-extension://lpfjfcebobk**************/"
]
}
UPDATE -1
I was able to solve this by creating a bat file which in turn calls the dll file by the following command
dotnet my_app.dll
Also my bat file looks like this
#echo off

dotnet "my_app.dll" %*
and my app_manifest looks like this
{
"name": "myapp",
"description": "myapp",
"path": "C:\\Program Files (x86)\\myapp.bat",
"type": "stdio",
"allowed_origins": [
"chrome-extension://lpfjfcebobk**************/"
]
}
I'm trying to install cl-jupyter. (Debian)
I've done the following steps:
install gcl (apt-get install gcl)
install sbcl (apt-get install sbcl)
run command python3 ./install-cl-jupyter.py
try to run command sbcl --load ./cl-jupyter.lisp but I get the following and don't know what to do. I've tried to choose all option, but nothing happend.
Output:
This is SBCL 1.2.4.debian, an implementation of ANSI Common Lisp.

Now I can see the SBCL Lisp kernel in jupyter but it doesn't work and breaks all the time when I try to write and run smth.
Please, help
I've done it! Now it works fine.
1)I forgot to install quicklisp
2) here i just put right paths to cl-jupyter.lisp, /src, /cl-jupyter:
{
"argv": [
"sbcl","--non-interactive", "--load",
"/path/to/cl-jupyter/cl-jupyter.lisp",

I have a problem with my build system specified in project settings. Currently my project settings look like this
{
"build_systems":
[
{
"file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
"name": "Anaconda Python Builder",
"selector": "source.python",
"shell_cmd": "$project_path/bin/python -u $file"
}
],
"folders":
[
{
"file_exclude_patterns":
[
"pip-selfcheck.json",
"pyvenv.cfg"
],
"folder_exclude_patterns":
[
"lib",
"include",
"bin"
],
"follow_symlinks": true,
"path": "."
}
],
"settings":
{
"binary_file_patterns":
[
"*.jpg",
"*.jpeg",
"*.png",
"*.gif",
"*.ttf",
"*.tga",
"*.dds",
"*.ico",
"*.eot",
"*.pdf",
"*.swf",
"*.jar",
"*.zip",
"client/node_modules/**",
"data/**"
]
}
}
The actual problem problem is in the line:
"shell_cmd": "$project_path/bin/python -u $file"
Every time I close sublime and reopen it my shell_cmd gets substituted with this
"shell_cmd": "\"python\" -u \"$file\""
Which fails my build. Is there a way to fix this problem? What do I do to disable this automatic substitution?

I already answered this question in the Anaconda's issues tracker but I will do it here for any other user that lands in this question with a similar problem.
That specific build system is used by Anaconda itself and that is why it is called "Anaconda Python Builder", it will update the "shell_cmd" with anything that you used as configuration for your "python_interpreter" setting into your anaconda's settings file (general, user or per project).
If you have specific needs for your build system, you should create a new build entry with your own options and stick to that one. Anaconda's build system is a convenience for users that need to use their configured Python interpreter instead of the embedded ST3 one.
I solved this issue without a custom build system by adding python_interpreter: 'full/path/to/python' to the settings dictionary. python part in the Anaconda Python Builder shell_cmd gets replaced with it.
