I am on a Windows 10 computer, running python 3.7.5. After installing plotly using “python -m pip install plotly” I am unable to execture “import plotly”. It fails with the following message. If anyone knows why this doesn’t work on my default installation, please let me know.

This problem was solved after switching from Python 3.7.5 to 3.8. So probably a version incompatibility somewhere, but I believe this issue is already documented
