Runtime Parse Error When Using Semantic Kernel In Python Project

[vsfeedback]

This issue has been moved from a ticket on Developer Community.

---

[severity:I'm unable to use this version]
I am trying to use Semantic Kernel in a Visual Studio 2022 Python project but I get the following runtime exception:
(7, [('expected', 'letter or digit', None)]) at the line import semantic_kernel.

Steps to reproduce the error:

1. Create new Python Project
2. Add 'import semantic_kernel'
3. Run the application

Application stops with the exception:
(7, [('expected', 'letter or digit', None)])

I am using Python verion 3.9 (64-bit) and semantic-kernel (0.9.6b1)

Thanks for reaching out. Is your code in a public repo or could you provide code samples that help us repro this issue? Thanks!

Thanks! I don’t see your environment included in the repo, and I wasn’t able to repro the issue. Based on the error message, it seems like a compatibility issue with the semantic-kernel package’s dependency on pymeta. Could you try updating or reinstalling both semantic-kernel and pymeta? You might also want to run the script outside of Visual Studio to check if it’s specific to the IDE

I have updated and tidied the project, creating an environment.
The environment has 'semantic-kernel==0.9.6b1'.
However if I run with from semantic-kernel import KernelI get error - invalid syntax, because of the hyphan.
If I edit to to from semantic_kernel import Kernel I get the exception - (7, [('expected', 'letter or digit', None)])

Note the inconsistency between semantic-kernel (with a hyphan) and semantic_kernel (with an underscore).

I am able to create a Python project with semantic_kernel in VS Code without issue.

I had the exact same issue, and I solved it. Posting so if others run into this they can also resolve.

Fix:
Delete Workspace Settings
.vscode/*

Delete Python Extension Cache
%APPDATA%\Code\User\workspaceStorage (I think this was the issue, but no way to validate/verify)
%APPDATA%\Code\User\globalStorage\ms-python.python

Delete Virtual Environment Metadata
.venv/*

After deleting all of this, I reran my pip installs and things worked out... This issue drove me crazy.

For me, the issue just randomly started happening when I was trying to run some tests.

I ran into the same issue and realized I had the User Uncaught exception option selected under Breakpoints. Once I unchecked it, I was able to debug as expected.

I'm encountering an exception when attempting to debug a Python project in Visual Studio 2022. The project uses Python 3.13 and the semantic-kernel library, version 1.36.2. The exception occurs immediately upon starting the debug session.
