@ilpomo It it usually a bad idea to ask for people to explain things to you as though you were 5 years old, as the answer is likely to be “you are not yet old enough to understand complicated software”. That is not a good starting point if you really want people to help you.
As @Bryan has said, you don’t need to use Bokeh if you want to generate a PNG file. Bokeh is complicated software that produced high-quality high-performance interactive graphics in a web browser. You do not need all of that complexity if you just want the equivalent of a static screenshot of the final output.
If you really want to use Bokeh and want specific advice:
- Use
condanotvirtualenv. - Don’t download binaries and put them in system directories and expect them to work. Use your distro’s package management system instead.
