Pyinstaller compatibility

[skornel02]

Hi,
I am currently trying to compile the following simple python script to an executable with PyInstaller:

import skl2onnx
print("hello world!")

I am not very familiar with the ecosystem so I'm interested if this is something that may or may not even work or has anyone managed to make this work.

Output of the executable (on Windows w/ Python 3.7.1)

Traceback (most recent call last):
  File "test.py", line 1, in 
  File "", line 983, in _find_and_load
  File "", line 967, in _find_and_load_unlocked
  File "", line 677, in _load_unlocked

Thank you for your help in advance!

I guess inpsect expects to see physical files but pyinstaller removes the physical file. It could happen with other modules. The code using inpsect is just doing validation and could be disabled.
