I am trying to install a package called \"simpleguitk\" via pip. (On Ubuntu 16.04 with Python 3.5)
After running
sudo -H pip3 install simpleguitk
The module may be installed but the program doesn't run. This happens because of 2 different versions of python co-existing. So run your Py Script with the location of the python version you have installed the module for, say usr/bin/python python.py or /usr/bin/python3 python.py.
Hope this helps in your progress!
