Cannot select current python interpreter as kernel

[pculbertson-bdai]

Applies To

• [ ] Notebooks (.ipynb files)
• [ ] Interactive Window and\/or Cell Scripts (.py files with #%% markers)

What happened?

Using the suggested (but complicated) workflow to pick a custom interpreter, I run:

• Python: Select Interpreter -> select my interpreter
• Within my notebook, I click Select Kernel->Python Environments. The current python interpreter is not available.

Ironically, I can run Jupyter: Create Interactive Window which connects just fine. I just can't run an existing notebook :upside_down_face:

I should note my workflow is pretty nontraditional -- I'm using a python executable built with Bazel that changes some paths etc on startup. But still, I can run it fine from the command line + sometimes can pick it as a kernel using the above workflow -- it just stopped working randomly today (possibly due to a clean rebuild).

Really appreciate your help + sorry if my workflow is silly. This is a possible duplicate of many issues also (#15086, #15087, and their duplicates).

Running Jupyter locally or remotely?

[DonJayamanne]

Sorry you are running into this issue. What is the name of the interpreter that you have selected via Python: Select Interpreter

Please could you enable logging as follows:

• Open settings & go into Jupyter->Logging
• Change the value to trace
• Reload VS Code,
• Attempt to repro the issue & then copy the output from the Jupyter output panel (use the command Jupyter: Show Output to get to the logs).
• Can you run the two and share the logs?
  • Select Kernel->Python Environments
  • Jupyter: Create Interactive Window

[pculbertson-bdai]

Sure, here are the logs from the following steps:

• Python: Select Interpreter -> /home/pculbertson_theaiinstitute_com/starfish/bazel-bin/sam2_python (custom executable)
• Select Kernel->Python Environments (not available)
• Jupyter: Create Interactive Window (successful, run import torch to ensure package paths are correct).
