This post describes how you can fix the python error
No module named 'winrandom'. This is typically found when you are using the
coinbase python module.
What is the No module named ‘winrandom’ error
This python error may occur whenever you try and use a module that requires the
winrandom module. I found this problem occurring when I was importing the coinbase python module. This is because this includes and uses the
The full error log of the error is copied below.

ImportError: No module named 'winrandom'
This error occurs due to the way the imports works in the
pyCrypto library. In the next step I will describe how we can fix it.
Fixing the No module named ‘winrandom’ error
To fix the no module error we need to modify one of the files used by
pyCrypto. First we need to locate the directory Python3 is installed in.
The most common location python is installed in is:
Where XX is the version number. In my case I have installed python to
Once you have located the python directory you need to go into the
The most common location this will be is:
In my case this is:
Once in this directory you need to open the
nt.py file and find the line
This line needs to be changed from:
from . import winrandom
Once this has been done your modules using
pyCrypto will start working. This resolved a relative import issue with this python module.
