I have downloaded the pycryptodome python module wheel format file (pycryptodome.whl) from this link.

Now when I try to import and use it as follows

from Crypto.PublicKey import RSA

I get

ImportError: No module named Crypto.PublicKey

I have another module called PyVMOMI (pyvmomi.whl) where I do not see this problem. I can very well import any of its module files without any error.

Note: the directory where the *.whl file is located is set in the PYTHONPATH variable already.

Wheels are not meant to be directly importable. While this may work with simple packages, it is not guaranteed to work for all wheels so I wouldn't rely on it. See PEP 491, section Is it possible to import Python code directly from a wheel file?

Even with ordinary zipfiles in sys.path, no dynamic libs will be imported from zipfiles. Quoting PEP 273, section Specification:

Any files may be present in the zip archive, but only files *.py and *.py[co] are available for import. Zip import of dynamic modules (*.pyd, *.so) is disallowed.

This is what happens with pycryptodome: it ships C extension modules, precompiled into dynamic libs, which are not imported from wheel. You will need to install the wheel to be able to use the code from extensions:

$ pip install pycryptodome
