'No module named flask' in VSCode even when I have installed flask

I have my Flask installed in my main directory for playing with Flask projects and I don't want to change it (its name is tryFlask).
My project is in one of the subdirectories to tryFlask (main_project).
How should I config my launch.json so that it doesn't throw errors when I try to debug?
Current config which throws:
{
"version": "0.2.0",
"configurations": [
{
"name": "Python: Flask",
"type": "python",
"request": "launch",
"module": "flask",
"env": {
"FLASK_APP": "my_app.py",
"FLASK_ENV": "tryFlask",
"FLASK_DEBUG": "1"
},
"args": [
"run",
"--no-debugger",
"--no-reload"
],
"jinja": true,
"justMyCode": true
}
]
}
And yes I have already checked "FLASK_APP": "my_project/my_app.py". Doesn't work. Neither does reinstalling dependencies or even choosing different interpreters from venv's bin subdirectory.

If you want to use flask with vscode, following this tutorial is a good start.
According to the question in your post, if you want to specify the python interpreter when debugging, you can add the python configuration to launch.json
Simple example:
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "Python: Current File",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "integratedTerminal",
"justMyCode": true,
// Modify the python interpreter with flask installed on your machine
"python": "C:\\WorkSpace\\pytest10\\.venv\\Scripts\\python.exe"
// "python": "${workspaceFolder}/.venv/Scripts/python.exe"
}
]
}

Fix the following: "pydevd warning: Computing repr of <something> was slow (took 0.35s)" in VS CODE

I'm working with Python with VSCode and I'm struggling with the following since this year:
pydevd warning: Computing repr of mlb (MyLibrary) was slow (took 0.35s)
Source: Debug Unit Test
This message appears for a varieties of packages, but the fix reported here:
pydevd warnings in Visual Studio Code Debug Console
is not working. I followed the relative suggestions to change the variable PYDEVD_WARN_SLOW_RESOLVE_TIMEOUT in settings.json:
"launch": {
"configurations": [
{
"name": "Python: Current File",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "integratedTerminal",
"env": {
"PYDEVD_WARN_SLOW_RESOLVE_TIMEOUT": "10"
}
}
],
"compounds": []
},
I also tried to apply the same to launch.json:
{
"version": "0.2.0",
"configurations": [
{
"name": "Python: Current File",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "integratedTerminal",
"env": {"PYDEVD_WARN_SLOW_RESOLVE_TIMEOUT": "10"},
"cwd": "${fileDirname}"
}
]
}
This is the VS Code version:
Version: 1.70.2 (user setup)
Commit: e4503b30fc78200f846c62cf8091b76ff5547662
Date: 2022-08-16T05:35:13.448Z

Do you see anything wrong? any other suggestions?

Time out waiting for launcher to connect in VS code

I did python debugging in VS code.
The following is the launch.json file:
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "Python: Current File",
"type": "python",
"request": "launch",
"stopOnEntry": false,
"python": "${command:python.interpreterPath}",
"program": "${file}",
"cwd": "${workspaceFolder}",
"env": {},
"envFile": "${workspaceFolder}/.env",
"debugOptions":[
"RedirectOutput"
],
"console": "integratedTerminal"
}
]
}
The following is settings.json file:
{
"python.pythonPath": "c:\\Users\\susan\\Documents\\PythonScripts\\venv\\Scripts\\python.exe",
// to fix 'Timeout waiting for debugger connections'
"python.terminal.activateEnvironment" : false
}
When I debug the python script in VS code, I got Time out waiting for launcher to connect and cannot debug the python script.
May I know how can I solve this issue?

Its very simple. Open the launch.json file and add the following into it:
{
"name": "Python: Debug Console",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "internalConsole"
}
Then save and exit it. Whatever you do, DO NOT clear the text already in there or else it may make it worser

If for whatever reason "internalConsole" isn't a good solution:
in your shell script:
export PROCESS_SPAWN_TIMEOUT=30
or just hack the code directly (will be reverted if you update the extension):
.vscode-server/extensions/ms-python.python-2022.18.2/pythonFiles/lib/python/debugpy/adapter/launchers.py[161]:
change:
timeout=(None if sudo else common.PROCESS_SPAWN_TIMEOUT)
to:
timeout=30,

How to set up Python in VS Code?

I'm new to python (and in coding in general). I'd like to ask some help to set up python on VS Code. I've tried to follow several guides but none of them were really helpful.
The following have been downloaded:
Python 3.6
VS Code
Python extensions

1) Install VS Code
2) Go to View > Command Palette
3) Type ext install and click on Install Extensions
4) Search for Python and install it
5) Reload VS
6) Start coding

This worked for me:
.vscode/settings.json:
{
"python.linting.pylintEnabled": false,
"python.pythonPath": "python.exe"
}
.vscode/tasks.json:
{
"version": "2.0.0"
}
.vscode/launch.json:
{
"version": "2.0.0",
"configurations": [
{
"name": "Python",
"type": "python",
"request": "launch",
"stopOnEntry": false,
"pythonPath": "${config:python.pythonPath}",
"program": "${file}",
"cwd": "${workspaceRoot}",
"console": "internalConsole",
"debugOptions": [
"WaitOnAbnormalExit",
"WaitOnNormalExit",
"RedirectOutput"
]
}
]
}
You can replace "program": "${file}", with "program": "${workspaceRoot}/main.py", to run your main file no matter which file you've selected but I found that that makes errors like syntax errors sometimes not display correctly if at all.

How to use visual studio code to debug django

I'm new at django development and come from desktop/mobile app development with Xcode and related IDE.
I have to use Django and I was wondering if there was an efficient way to debug it using Visual Studio Code (or Atom).
Any help related to Django IDE would be helpful too.

For VSCode (full disclosure, I'm one of the VSCode developers) try installing the Python extension to get started.
This documentation covers debugging Django. There should be a included debug configuration or you can add your own to the launch.json file:
{
"name": "Django",
"type": "python",
"request": "launch",
"stopOnEntry": false,
"pythonPath": "${config.python.pythonPath}",
"program": "${workspaceRoot}/manage.py",
"args": [
"runserver",
"--no-color",
"--noreload"
],
"debugOptions": [
"WaitOnAbnormalExit",
"WaitOnNormalExit",
"RedirectOutput",
"DjangoDebugging"
]
}
The Python extension also provide many other features that you may find useful.

VSCode has an official tutorial explaining this:
https://code.visualstudio.com/docs/python/tutorial-django
There are several steps that need to be taken, which I don't all want to write out manually, since there are quite some steps, but I'll try to summarize what needs to be done:
The text below is basically a partial copy of the above tutorial, I am not claiming I came up with this myself.
1. Make sure to check out the prerequisites (use VS Code Python extension, install Python on local machine) link to docs
2. Use Python virtual environment link to docs
Besides using a Python virtual environment, you also need to select the Python executable inside this virtual environment as the interpreter in VS Code. This can be done like so:
In VS Code, open the Command Palette (View > Command Palette or (Ctrl+Shift+P)). Then select the Python: Select Interpreter
Then you select the Python executable inside your virtual environment, which you can recognize by it's path.
3. Create debugger lauch profile
as described here, in the documentation
upper left of the VS Code window)
4. Now you can start debugging
this part of the documentation will give you an introduction on how to do that

Only experimental configuration works for me.
{
"name": "Django",
"type": "pythonExperimental",
"request": "launch",
"program": "${workspaceFolder}/manage.py",
"args": [
"runserver",
"--noreload",
"--nothreading"
],
"django": true
},
Standard config causes Unverified breakpoint issue.

{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "Python: Django",
"type": "python",
"request": "launch",
"program": "${workspaceFolder}\\manage.py",
"args": [
"runserver"
],
"django": true
},
{
"name": "Django: makemigrations",
"type": "python",
"request": "launch",
"program": "${workspaceFolder}\\manage.py",
"args": [
"makemigrations"
],
"django": true
},
{
"name": "Django: migrate",
"type": "python",
"request": "launch",
"program": "${workspaceFolder}\\manage.py",
"args": [
"migrate"
],
"django": true
},
]
}

Nothing worked for me until I had disabled auto reload (--noreload as an argument is crucial, not really sure why it causes problem with debugging)
