We need to add hiddenimport

 

Check the official documentation

--hidden-import MODULENAME, --hiddenimport MODULENAME

Name an import not visible in the code of the script(s). This option can be used multiple times.

 

Not need to modify the configuration package, when the package is introduced directly in the parameter can be

pyinstaller -F --hidden-import=pywt --hidden-import=pywt._extensions._cwt app.py
