No module named Crypto.Cipher Open EdX

Question

Tried to import this code to our edx site encrypt data in python but it requires a package which is pycryptodome. Tried installing it using:

pip install pycryptodome

but it still shows an error everytime I call

from Crypto.Cipher import AES

.

Sorry for a very vague question since I'm not really a python/django/open edx developer and was just tasked to support the project and did some heavy research but still no light.
