Hmmm, I think you need to be running Python 3.

[xxott]

allready tested in python 3, and same error,
what operating system are you using?

On python3 virtuanev i get:

>>> from crypto import HDPrivateKey, HDPublicKey, HDKey
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/private/tmp/web3/ethereum-bip44-python/crypto.py", line 22, in <module>

    from Crypto.Util.py3compat import byte_string
ImportError: cannot import name 'byte_string'

when you got "cannot import name 'byte_string'", you can try:

pip3 uninstall pycrypto
pip3 uninstall pycryptodome
pip3 install pycryptodome
