Failed to execute script fbs_pyinstaller_hook

I'm trying to create an executable file from the my PyQt5 application. my system specs:

ubuntu 18.04
python (3.6.9)
fbs (0.8.9)
matplotlib (3.3.0)
numpy (1.19.1)
pandas (1.1.0)

I'm following fbs tutorial to build a executable file from my application. I run the application without error with fbs run command.

The fbs freeze command produce this output:

-c:12: MatplotlibDeprecationWarning: 
The matplotlib.backends.backend_qt4agg backend was deprecated in Matplotlib 3.3 and will be removed two minor releases later.
Done. You can now run `target/DataVisualization/DataVisualization`. If
that doesn't work, see https://build-system.fman.io/troubleshooting.

But I'm importing version 5 of matplotlib.backends.backend_qt4agg in my code as:

from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg, NavigationToolbar2QT as NavigationToolbar

when I run the executable file from

~/MyProject/target/AppName

I get this error:

./AppName

[1331] Failed to execute script fbs_pyinstaller_hook

I have checked the solutions given in these links, but none of them came handy!

Any ideas of what to do?

Solution

I entirely gave up using FBS.. pyinstaller works very well for compiling PyQt5 code.. try using just pyinstaller and see if that works.
