Jupyter notebook failed to load DLL

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

C:\Users\Ganesh>jupyter notebook
Traceback (most recent call last):
  File "C:\ProgramData\Anaconda3\Scripts\jupyter-notebook-script.py", line 6, in <module>
    from notebook.notebookapp import main

    from zmq.eventloop import ioloop

    mod = __import__(name, fromlist=public_api)
  File "C:\ProgramData\Anaconda3\lib\site-packages\zmq\backend\cython\__init__.py", line 6, in <module>
    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)

This happened to me when creating a new environment with the latest anaconda package (at the time of my answer at least). The folder zmq in the base environment ([1] .../Anaconda3/Lib/site-packages/zmq) was correct, it was actually the folder zmq in the new environment ([2] {python_env_dir}/{env}/.../site-packages/zmq) that was corrupted.

Solution: I deleted the folder [2], and I copied the folder [1] in the previous place of the folder [2]. And this issue was solved for me.

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
