Failed to import a installed python package

Hi guys. I would like to import an external python package named Pinocchio in the embedded script editor. Here are the codes:

import sys

import pinocchio

But it gave me a weird error which may relate to a *.so file:

The code in the script editor is rather simple:
The first part of the above code is to validate that Isaac sim is running in the virtual environment created by conda. It seems that it is indeed.
The second part is to import the Pinocchio package. The package seems to be correctly located, however a *.so-file-related error shows up.

More details:

I really need this package to develop algorithms in Isaac Sim, and I appreciate any help or comments.
