Matplotlib window doesn't open

[JogeHB]

Hey there,
I'm struggling with pyinstaller and matplotlib. I'm able to get a .exe from my python code but when I include something with matplotlib the console of the exe doesn't open the matplotlib window and ends the run.

I simplified it to:

import matplotlib.pyplot as plt

x = [0,1,2,3]
y = x

plt.plot(x,y)

plt.show()

I run pyinstaller with:

pyinstaller --debug=all --hidden-import matplotlib.backends --distpath path2dist --workpath path2work simple_plot.py

Running the resulting .exe works on the same computer/user (the matplotlib window opens). However, when I change the user for testing the compatibility of the .exe, the console runs trough the program without opening the matplotlib window. The last lines of the console are:

import 'matplotlib.backends.qt_editor._formsubplottool' # <_frozen_importlib_external.SourcelessFileLoader object at 0x0000027ED17817F0>
import 'matplotlib.backends.backend_qt5' # <_frozen_importlib_external.SourcelessFileLoader object at 0x0000027ED1768AF0>
import 'matplotlib.backends.backend_qt5agg' # <_frozen_importlib_external.SourcelessFileLoader object at 0x0000027ED174DBB0>
import 'matplotlib.pyplot' # <_frozen_importlib_external.SourcelessFileLoader object at 0x0000027ECF8ED7C0>
# PyQt5.QtX11Extras not found in PYZ

So, no direct Error message.
I'm working on Windows, Python 3.8.5, PyInstaller 4.2, Matplotlib 3.3.2.

My normal, non-reduced python code defines a gui in which you can press a button and a matplotlib plot should appear. There, when pressing the button, no matplotlib window occurs and the gui closes. Before doing so, everything works fine for the other parts of the gui. After the gui has closed you can find the same last lines within the console as shown above.

What I already checked:

• Pyinstaller hooks (nltk, matplotlib, matplotlib.backends). Matplotlib related updates of them suggested in earlier questions are already implemented in PyInstaller 4.2.
• PyInstaller messages related to matplotlib during .exe generation:

• Reverting to older versions of matplotlib didn't work & causes other problems due to other dependecies within the rest of the code.

Looking forward to some new ideas to solve the issue.
Thanks in advance!

Since you're using anaconda, the silent crash of frozen application is probably caused by numpy missing the libiomp5md DLL.

Try using develop version of PyInstaller (which has #5168 merged). Or, try to bundle that missing DLL using work-around from #4968 (comment).

Nice! The change of hook-numpy.py as described in #5168 makes it work.

Thanks a lot!
