GUI executable

[pgaviganHC]

A build process has been setup for a standalone exe of a console app for clients to use the table processing tool. This needs to be expanded to also generate an exe of the GUI.

I think the problem is due to dash callback: plotly/dash#1885
Tried this tutorial (https://github.com/JonThom/dash-background-callbacks-pyinstaller) and got it to work but not sure how to apply it to our exe

For reference, the error is:
File "dash_callback.py", line 318, in wrap_func
File "dash\long_callback\managers_init_.py", line 83, in register_func
File "dash\long_callback\managers_init_.py", line 103, in hash_function
File "inspect.py", line 1147, in getsource
File "inspect.py", line 1129, in getsourcelines
File "inspect.py", line 958, in findsource
OSError: could not get source code

So far exe is made and GUI opens but there is an issue with the call backs. Nothing happens once you submit a file.

Steps taken so far:

• Recreate the venv before running the build
• Run build.py

Add these lines to the GUI.spec file:

• datas += [('table_processing\long_callbacks.py', '.'), ('cache', 'cache')] (line 25)
• datas += [('.venv\Lib\site-packages\torchvision', 'torchvision')] (line 26)

Then type in terminal:

• pyinstaller --noconfirm GUI.spec
