pymodule, pyattr, pyclass, pygetset, and pymethod attrs generate numerous errors related to rustpython_vm when used

Summary

Using the exact code provided on https://rustpython.github.io/docs/interop/rust_from_python.html generates a lot of errors

Expected

It functions and creates a rustpython module.

Actual

Thank you for the report. Did you add rustpython-vm to the dependency?

I do not remember as it has been more than two months. If say double check the link i provided as i used that exact code.

Sure, I will check the code. The environment doesn't come with the code though.

This error is not likely to be happened when it is added as dependency.

error[E0432]: unresolved import `rustpython_vm`

And I am sorry for the late response. I had to check it earlier.
