>>> import sabctools
AttributeError: module '_ssl' has no attribute '__file__'. Did you mean: '__name__'?

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<python-input-0>", line 1, in <module>
    import sabctools
  File "/.venv/lib/python3.13/site-packages/sabctools/__init__.py", line 2, in <module>

In PBS, the _ssl extension module is linked into libpython.so and therefore doesn't have an appropriate standalone file name, so __file__ isn't set on the Python module.

Python doesn't mandate that __file__ be set for a module. It is arguably a bug of sabctools to expect __file__ to exist.
