ImportError: cannot import name 'ssl' from 'urllib3.util.ssl_'

I'm trying to start a python code from cmd. I use python 3.7 and Anaconda. I initially had a DLL problem. Following some answers in the forum I have inserted the path 'C:\Users\andre\Anaconda3\envs\py37\Library\bin' in the environment variables on Windows OS. After that I had the following error:

When I run my script in my Jupyter Notebook I don't see this error message, but when I run it on the command line I get the error above.
