How Do I Get the IDE to Find My Imports

[buran]

I have created copies of the folders anywhere I think it could be searching.

Actually this may be part of the problem, e.g. why it finds gr, but not what gr imports.

I have a very short (20 lines or so) program that runs under 2.7 but not 3.7.

You must understand that even if you fix the imports (it finds the desired modules) it still will not work, because there are syntax differences between 2 and 3. For example these issues demonstrates changes that were made/must be made between gnuradio 3.7 and 3.8, so that 3.8 would work with python3

That said I'm not sure (i.e. I may be wrong, but I don't have time and desire to dig further) gnuradio is intended to work with different interpreter from the one that was bundled with it.

Somehow I just think that if I could get the python 2.7 version of IDLE to run or if I can figure out why python 3.7 won't chain through the import(s) I might break my log jam

I am bit confused - you said if you click on the file it works (using python2 - I guess the one that comes bundled). But not works when open it in python3 IDLE (I guess - system wide installation). Now you say it doesn't work with python2, when open in IDLE.
