When i am starting jupyter notebook from cmd prompt i get following error

C:\Users\Ganesh>jupyter notebook
Traceback (most recent call last):

    from . import (constants, error, message, context,
ImportError: DLL load failed: The specified module could not be found.

I had set following paths in system variable

C:\ProgramData\Anaconda3
C:\ProgramData\Anaconda3\Scripts
C:\ProgramData\Anaconda3Scripts\jupyter

Did i missed any path to add in system variables (OS version Windows 10)

Try to add the following directories to your env path as well: C:\ProgramData\Anaconda3\Library\mingw-w64\bin C:\ProgramData\Anaconda3\usr\bin C:\ProgramData\Anaconda3\Library\bin
