PR #44511: Fix get_docstring_indentation_level to handle compiled functions

file: transformers/utils/doc.py

Code snippet with the error def get_docstring_indentation_level(func): """Return the indentation level of the start of the docstring of a class or function (or method).""" # We assume classes are always defined in the global scope if inspect.isclass(func): return 4 source = inspect.getsource(func) first_line = source.splitlines()[0] function_def_level = len(first_line) - len(first_line.lstrip()) return 4 + function_def_level

Fix: Update transformers to the latest version

The issue is caused by a compatibility problem between the transformers library and the cython library. The latest version of transformers should resolve this issue.

Fix Plan

  1. Update transformers to the latest version:

pip install --upgrade transformers

2. **Verify the version**:
   ```python
import transformers
print(transformers.__version__)

This should print the latest version of transformers.

Verification

  1. Run the example script: If the error is resolved, the script should run without errors.
  2. Check the output: Verify that the expected output is generated.

Extra Tips

  • Always check for updates to the library before reporting issues.
  • Use pip install --upgrade to ensure you have the latest version of the library.
  • If you're using a virtual environment, make sure to activate it before updating the library.
