I have a Python script that is working fine from Processing->Toolbox->User Scripts. However, I have put some user defined functions in "my_functions.py" that I can call from "Timing_Advance.py".

The problem is, when I edit the functions in "my_functions.py" in the QGIS script editor, I have to restart QGIS for the changes to take effect. This is perhaps because, when I restart QGIS, it makes a "my_fucntions.pyc" file and keeps it in the same location. The .pyc file is not update when I edit the user defined functions in "my_functions.py".

How can I update the my_functions.pyc file after editing, without having to restart QGIS?

UPDATE 24th Jan 2017 Looks like including the following lines isn't making any difference either

import sys
import py_compile

import my_functions

If I add some dummy lines like a "print" and re-run the script, the print doesn't give the desired output, till I re-start QGIS


Try using the following:

import py_compile
  • i added the suggested lines and then I added a dummy piece of code print "hi" in my_functions.py. if the code worked then I would have seen the response in the python console, but nope – Arindam Jan 23 '17 at 14:37
  • @Arindam - Hmm, perhaps this post might help: Re-import custom functions without restarting QGIS – Joseph Jan 24 '17 at 12:37
  • I must be missing something elementary. I added these lines import imp, my_functions imp.reload(my_functions) from my_functions import * but now I get the error "See log for Details" – Arindam Jan 26 '17 at 4:31

    Thanks for the tip. I just removed "imp" and it worked like a charm. Found the answer here <stackoverflow.com/questions/1517038/python-refresh-reload> – Arindam Jan 27 '17 at 7:38
