I have just installed Ubuntu 18.04 LTS. After running a python script, I'm receiving this error:
ModuleNotFoundError: No module named 'cmath'
I know that cmath should be already installed. I have found this question Python 3.7 cmath module import error but it's related to python 3.7 . Does it also affects python 3.6? Do you have any ideas how to fix it? Thank you!
Python version is 3.6.5
