pycrypto is installed (when I run pip list one of the result is pycrypto (2.6.1))
and it works but when I would like to use the MODE_CCM it returns: module 'Crypto.Cipher.AES' has no attribute 'MODE_CCM'
My Python version: Python 3.5.2 :: Anaconda 4.2.0 (x86_64)
By using python 3, i solved it by installing pycryptodome (pip3 install pycryptodome).
 No need to replace Crypto by Cryptodome
python: module 'Crypto.Cipher.AES' has no attribute 'MODE_CCM' even though pycrypto installed
