Does invalid module named error lead to ModuleNotFoundError

[Robert Gottesman]

I am trying to wade through my errors with PyInstaller and was doing a decent job until I ran across this error.

ModuleNotFoundError: No module named 'concurrent.futures._base'
[15692] Failed to execute script run

I had seen that kind of error before but adding paths to my spec file seemed to work. But not in this case.

When I looked at the warn-run.txt file I saw this message as well

invalid module named concurrent.futures._base - imported by concurrent.futures (top-level), concurrent.futures.thread (top-level), concurrent.futures.process (top-level), C:\Users\suppo\Documents\Technology\Programming\Python\Projects\WikiExporter\run.py (top-level)

I assume this is the cause of my ModuleNotFoundError.  I have tried adding to my hiddenimports spec entry as follows: hiddenimports=['concurrent.futures'].  But that did not change the message.  Adding log-level=DEBUG also did not yield any info.

I have attached my warn-run.txt file.. The full error message is below.

Can someone give me some hints of where I go from here?

Forgot to mention, I am running the newest version (3.5) on Windows 10.

ok, my problem is fixed (but not with an elegant solution).  Testing modules individually had PyInstaller working  .. however, together as a total package I was getting errors as listed.  Digging into this deeper there seemed to be a namespace issue on how one module was setup.  I worked around by just not using that module in error.
