Miniconda3. ImportError: Unable to import required dependencies...

[PavelD0770]

When running the script in VS Code, an error is issued:

C:\Users\user>C:/Python/Miniconda3/envs/myenv/python.exe d:/Test/Test.py
Traceback (most recent call last):
File "d:/Test/Test.py", line 1, in import pandas
File "C:\Python\Miniconda3\envs\myenv\lib\site-ackages\pandas_init_.py", line 17, in "Unable to import required dependencies:\n" + "\n".join(missing_dependencies)
ImportError: Unable to import required dependencies:
numpy: DLL load failed: The specified module was not found.

What am I doing.

1. Install Miniconda3

2. I create myenv virtual environment in Miniconda3

3. Download packages there: pandas, numpy, etc.

4. Launch VS Code (Microsoft's Python extension installed)

5. I create a Python script file with text (for example):
   import pandas
   print ('pass ..')

6. I select the virtual environment myenv and run the script on
   performance.

7. I observe the above error :(

   Works from the console (miniconda), works from Visual Studio 2019, works from Pycharm too. From VS Code, it only works when changing to the virtual environment (venv) of Python 3.7, in which the packages from p. 3 are also installed. Those. the only problem is a bunch of VS Code and Miniconda3.

   A similar problem with numpy, matplotlib, scipy. C, for example, sqlalchemy, requests and some other third-party packages are all OK.

   Previously, VS code worked with the Miniconda3 virtual environment without any problems. Perhaps the problem appeared after installing and then uninstalling Anaconda Extension Pack.

The problem is that when choosing a virtual conda environment, this environment is not activated. To fix the problem, you must manually execute activate myenv (myenv is the environment name) in the VS code terminal.

[PavelD0770]

Yes, specifying Path for conda is necessary. But in other IDEs it works without environment variables. Still, this is a problem with VS code or the Python extension package for Visual Studio Code

Thanks for letting us know about this, @PavelD0770. Before we take a deeper look, it looks like you are trying to use conda and virtualenv together. Is that the case? If so, why? Using conda alone should be sufficient. Keep in mind that the extension expects one or the other, not both.

[PavelD0770]

Hello! At first I only used Python 3 without virtual environments to learn this language. Later I started to study Python course for data analysis. For this I installed Miniconda3. I created the conda virtual environment in order to gain new skills. And to my experiments and test tasks on the course program to perform separately. For the course I used Jupyter Notebook, and for my experiments - MS Visual Studio Code (VS Code I really liked).  Yes, for everything to work, I added the path to Miniconda to the Path environment variable. I didn't add anything to VS code settings. Only as a terminal chose cmd. Everything worked.At what point VS Code began to "swear" at the panda and numpy can not say for sure.

(The previous message did not finish. Accidentally sent is not complete.) At first I only used Python 3 without virtual environments to learn this language.

I didn't add anything to VS code settings. Only as a terminal chose cmd. Everything worked. At what point VS Code began to "sweat" at the panda and numpy can not say for sure. I first thought this happened after installing the Anaconda extension package for VS Code. Deleted - did not help. I reviewed the possible settings, but nothing helped. Helped only run the conda "activate myenv"command in vs code terminal. The script is started without any errors. I tried to install Python on another PC, then Miniconda, then envs. The mistake was repeated. The solution is also "activate myenv". It looks like something with envs conda activation. MS Visual Studio Code extension to Python and PyCharm JetBrains in this environment are working without problems (from conda, with conda envs, c, Python, c Python virtualenv) Now I uninstalled Miniconda (not really necessary), I use only Python and virtualenv (configured for all the necessary tasks right now). It's okay!

[ericsnowcurrently]

So you are saying that everything is fine now that you have uninstalled miniconda?

Expected behaviour

The activation of the conda virtual environment is done before the debugger starts.

Additionaly a problem with the activation of conda environments exist, see problem 1 and 2 later.

Steps to reproduce:

    • Register Anaconda as the System Python 3.7 : YES
• Install VSCode 1.37.1 (User Installer)
  • Path : C:\Users\admin\AppData\Local\Programs\Microsoft VS Code
  • Additional Options
    • Open with Code for Folders Context Menu
    • Add to Path
• Install Extension
  • Python extension for Visual Studio Code 2019.8.30787
• Create conda environment within Anaconda Prompt (cmd.exe)
  • conda create -n pyTestAppCondaEnv python

Problem 1: Miniconda3 installation not correct

• Path environment variable is not configured properly for powershell
  • the conda command can not be found
• Path environment variable is configured properly for cmd.exe
  • no problems with cmd.exe

Possible solution for problem 1

• run conda init powershell

==> For changes to take effect, close and re-open your current shell. <==

• now conda environment can be activated by vscode (as seen in last line of output)
  • Problem: now not only conda but full python is available in all powershell terminals in Windows and in vscode

Problem 2: Extend path for powershell not sufficient

• Extend path environment var with C:\Miniconda3\condabin;
• this makes conda command available but the activation ist still not successfull
  • no python paths in path environment variable
