Exception: Cannot find PyQt5 plugin directories when using Pyinstaller despite PyQt5 not even being used

python python-2.7 python-3.x pyinstaller

A month ago I solved my applcation freezing issues for Python 2.7 as you can see here. I have since adapted my code to python 3.5 (using Anaconda) and it appears to be working. couldn't get pyinstaller working with Anaconda so switched to trying to generate an .exe using the standard Python 3.5 compiler. I am using the same settings as in the link above (pyinstaller --additional-hooks-dir=. --clean --win-private-assemblies pipegui.py), except I get the following error message instead: 

`Exception: Cannot find PyQt5 plugin directories`

This may be related? Except I'm using Pyinstaller and I don't have a setup.py so don't know how I can make use of the solution there, if at all

I find this error message bizarre because I am not using PyQt5, but PyQt4. Here is the full output:

I will say I also have no clue what to make of the TypeError: a bytes-like object is required, not 'str'This may be related? I only use binary mode with pickle a handful of times as far as I can tell this is my only usage:

pickle.dump( roiState, open( fileName, "wb" ) )
roiState = pickle.load(open(fileName, "rb"))

I don't have any errors when I run the application, only getting these errors when trying to generate an .exe using pyinstaller. Why?

Note also that Anaconda3 does pop up in the traceback above (why is it looking for binaries there?) but I:

  1. Uninstalled pyinstaller from Anaconda
  2. Am using the standard Python 3.5 (64-bit) compiler

Only thing I can think of that may be the culprit is that I'm no longer using the developer version of Pyinstaller (it just flat does not run in Python 3.5). I had to use the developer version to solve my freezing issue here when my code was written for python 2.7

I managed to fix the same problem I encountered (conda 4.5.4, pyinstaller 3.4) without uninstalling conda:

pip install PyQt5

conda already installed PyQt when I used conda install jupyter seaborn. Interestingly, using conda install PyQt5 does not fix my problem. I don't know why. In any case I hope this may help someone out there.
