Expected behaviour

No errors appear. Script is executed successfully.

Actual behaviour

Getting the following error:

Traceback (most recent call last):
  File "o:/cloud/documents/test/test.py", line 3, in <module>
    import pandas as pd
  File "C:\Users\<username>\Anaconda3\lib\site-packages\pandas\__init__.py", line 17, in <module>
    "Unable to import required dependencies:\n" + "\n".join(missing_dependencies)
ImportError: Unable to import required dependencies:
numpy: DLL load failed: The specified module could not be found.

Steps to reproduce:

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

  1. Set "python.pythonPath" to "C:\\Users\\<username>\\Anaconda3\\python.exe" in VSCode settings.
  2. Run this script from VSCode by pressing the play button:

import pandas as pd

Things to note:

  1. The DLL load failed error is not in red, so it’s not necessarily a system error.

  2. Pressing the Play button for the first time with the aforementioned script triggers the following error (in red) when VSCode tries to execute the conda activate base command:

conda : The term 'conda' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try 
again.
At line:1 char:1
+ conda activate base
+ ~~~~~
    + CategoryInfo          : ObjectNotFound: (conda:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

However, VSCode executes the following command immediately after: PS C:\Users\<username>> & C:/Users/<username>/Anaconda3/python.exe o:/cloud/documents/test/test.py which is when I get the DLL load failed error (again, not in red).

  1. Pressing the Play button for the first time with a different script (print("Hello World")) still triggers the term is not recognized error (in red) when VSCode tries to execute the conda activate base command. But the PS C:\Users\<username>> & C:/Users/<username>/Anaconda3/python.exe o:/cloud/documents/test/test.py command gets executed (by VSCode) successfully and prints out "Hello world".

  2. All scripts (including ones with numpy imports) run just fine from Anaconda prompt.

Hi @github-account1111, I think this might be an issue with Powershell. Could you try changing your default shell in vscode to ‘Command Prompt’ instead of Powershell?
