Expected behaviour

Being able to use the step-through debugger.

Actual behaviour

Any import of numpy results in an import Error. However, if the script is run from the terminal, this numpy import error does not occur. In other words, the issue is specific to the VS Code Python Debugger.

Exception has occurred: ImportError


IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.7 from "C:\Users\potassium\Miniconda3\envs\test_numpy37\python.exe"
  * The NumPy version is: "1.18.5"

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

import numpy will trigger the error when a Python module is executed with "Start Debugging".

I tried numpy 1.18.5 and 1.19. I reinstalled VS Code and Miniconda. Problem still remains. I didn't have this issue before.

We just want to quickly acknowledge that we have received the issue and will be looking into it soon.

Thanks @karrtikr appreciate it. Shout if you need more info from my end.

It looks like the code is not running within an activated conda environment when debugging it. Can you try this?

1. Anaconda prompt and cd to your workspace.
2. Activate the environment using conda activate
3. Start VS Code using code .

hi @karrtikr I followed your instructions and the debugger works when I use the Anaconda Prompt to launch code.

Thanks I can work with this. Is this the a temporary workaround or are you still figuring out another way to address this more permanently?

[karrtikr]

Great, conda activation is a tricky one to get right for us, but we have plans to fix it, until then please use the workaround. Closing in favor of #5344
