Visual Studio Code not letting me choose Virtual environment Python - Stack Overflow

This is a bug I cannot wrap my head around. I should first mention that everything works perfectly on PyCharm notebook Professional Edition (but I prefer VSCode's way of using notebooks).

When I click on Select Kernel, I only see my two base Python environments. Both work. I would however like to use one of my virtual environment. So I used the >Python: Select Interpreter option:

Here, it's easy for me to find the path/to/python.exe of my virtual environment (Python 3.12.5) by clicking on Enter interpreter path:

However, when I click and locate path/to/python.exe, nothing happens.

There is still the Select Kernel button saying that I have not selected any Python environment for my notebook.

Things I did:

• I restarted my computer.
• I uninstalled VSCode, and reinstalled VSCode.
• I looked for Windows Updates.
• I looked for VSCode Updates. None were found. I'm on 1.97.2.
• I installed ipykernel to my virtual environment but it was already installed.
• I made sure I had the Python extension enabled on VSCode.
• I made sure I had the jupyter extension enabled on VSCode.
• I made sure the base environments worked as expected when choosing them in Select Kernel. They did.
• I made sure everything worked with my virtual environments in PyCharm Professional. They did.
• I used python3 -m ipykernel install --user --name=projectname.

• By "nothing happens", do you mean that subsequently the chosen python.exe is not listed when using Python: Select Interpreter again? – mkrieger1 Commented Feb 24 at 15:04
• Correct. When I click on my python.exe, the window closes, and I'm back to square one without anything changed (or maybe something that I couldn't see did). – FluidMechanics Potential Flows Commented Feb 24 at 15:06
• Maybe the chosen python.exe was already chosen before? – mkrieger1 Commented Feb 24 at 15:07
• The only ones that appear in Select Kernel are the base ones. I just checked again, those do not point to the same path as my virtual environment and they do not contain the library that my virtual environment contains. – FluidMechanics Potential Flows Commented Feb 24 at 15:09
• Select Kernel is something different from Select Interpreter. Maybe Select Interpreter works but you think it doesn't because you expect it to also select a kernel (whatever that means exactly). – mkrieger1 Commented Feb 24 at 15:10

1. Enter interpreter path: path/to/python.exe Then >Jupyter: create interactive Window so that kernel will connect to the Python environment automatically. And now you can select the kernel in your ipynb.

Or

2. Add virtual environment to the workspace so that python can detect the python.exe.

We ran into the same issue multiple times. However, I noticed later that the issue is more repetitive when the venv location is outside the reach of your workspace base directory or too deep inside the sub folders. I suggest putting your Python venv in the main directory where your workspace is opened. Then restart VSCode if it doesn't run it.

Previous Answer
To start you can install conda

• Miniconda or Anaconda from the official website. After installation, open a terminal or command prompt.

To create a new environment named myenv with Python 3.10, run:

conda create --name myenv python=3.10

Then you can manage all your python package in that myenv environment; Let me know if it solves this problem;

VS code should pick it up automatically;

Current Answer

1. Activate your environment in a terminal source activate myenv
2. Install ipykernel if not already present: pip install ipykernel
3. Register the kernel explicitly: python -m ipykernel install --user --name myenv --display-name "Python (myenv)"

The above is similiar to one of the other solution provided;

Here is what we can do next:

1. Open VSCode and make sure you have the Python and Jupyter extensions installed and enabled.
2. Reload or Restart VSCode after installing new extensions or registering a new kernel.

Additional step try to clear and refresh interpreter cache:

1. Open the Command Palette (Ctrl + Shift + P)
2. Do this clear cache and reload window
3. Reload VSCode.

Now even more checks (Verify VSCode Settings)

1. Go to File → Preferences → Settings (or open Command Palette → “Preferences: Open Settings (JSON)”).
2. If you have a custom path for virtual environments, check: "python.venvPath": "C:\\path\\to\\environments"

I replicated the issue in my machine by creating a virtual environment outside the workspace as mentioned before, and I solved it this way:

1. Navigate to your venv and activate it in the terminal.

2. Install ipykernel in your virtual environment.
   pip install ipykernel

3. Register the virtual environment as a jupyter kernel
   python -m ipykernel install --user --name myenv --display-name "Python (test)"
   If everything goes well, you should see a message like:
   Installed kernelspec myenv in C:\Users\...\jupyter\kernels\myenv

4. Go to your notebook in VSCode and use the command palette Jupyter: Select Interpreter to Start Jupyter Server to select the new kernel. If the kernel does not appear immediately, try restarting VSCode.
