We created a virtual environment with system-site-packages and trying to run 2 python scripts.
1. First script errors out with the below message:
reader = PyPDF2.PdfReader(file)
AttributeError: module 'PyPDF2' has no attribute 'PdfReader'

2. Second script errors with below message:   
_ASN1 = OpenSSL.crypto.FILETYPE_ASN1
AttributeError: module 'OpenSSL' has no attribute 'crypto'

Here  are the versions we have in the system:

root@XXXXX:/root #/opt/freeware/bin/python3 -m pip list
Package            Version

Hello,

Please share the steps you used for creating virtual environment and steps you used to install PyPDF2.

# python3
Python 3.9.20 (main, Sep 27 2024, 03:16:26) 
[GCC 10.3.0] on aix
Type "help", "copyright", "credits" or "license" for more information.
>>> import OpenSSL
>>> _ASN1 = OpenSSL.crypto.FILETYPE_ASN1
>>> 
>>> 

Thanks
Ranjit

Try creating fresh virtual env and install below version of package . I don't see the issue you mentioned here. At least not from python cli prompt.

# python3 -m pip list | grep -i -E 'pyOpenSSL|PyPDF2'
pyOpenSSL                     25.1.0
PyPDF2                        3.0.1

# python3 
Python 3.9.20 (main, Sep 27 2024, 03:16:26)

>>> from PyPDF2 import PdfReader
>>> reader = PdfReader("/ranjit/sample.pdf")
>>> 
>>> from PyPDF2 import PdfReader
>>> number_of_pages = len(reader.pages)
>>> print(number_of_pages)
1
>>> import OpenSSL
>>> _ASN1 = OpenSSL.crypto.FILETYPE_ASN1
>>> exit()
