ImportError: No module named Crypto.Util.py3compat

[Vijendra07Kulhade]

from crypto.PublicKey import RSA

and Using

with open('private_key.pem', 'r') as f: key_text = f.read()
private_key = RSA.importKey(key_text)

Above code gives error
ImportError: No module named Crypto.Util.py3compat

I installed pycrypto 2.6.1. Looks like the issue is the way it installed.
It is installed with crypto in my virtualenv. so when I import it as crypto, internal imports like Crypto.Util.py3compat throws error.
