I do not know exactly why this bug arises, but here are the facts: - when I download http://ftp.de.debian.org/debian/pool/main/p/python-pyqtgraph/python3-pyqtgraph_0.10.0-4_all.deb and inspect this package, it misses the directory /usr/lib/python3/pyqtgraph/widget, hence the error message reported in the bug report: "ModuleNotFoundError: No module named 'pyqtgraph.widgets'"
- when I tried to know why this directory is missing from the package, I cloned the fork https://salsa.debian.org/georgesk/python-pyqtgraph and built the package again with debuild: then, the same bug happens: /usr/lib/python3/pyqtgraph/widget is missing again - I patched the file setup.py, in order to view better le list of packages and sub-packages which were to install, and added a single line to print a message with the value of the variable allPackages: [line 68] print("Hello, allPackages =", allPackages) it happens that 'pyqtgraph.widget' is part of the list allPackages sometimes, and sometimes, not. THIS IS WEIRD! - it seems that the function listAllPackages from the module tools.setupHelpers is not completely reliable, though I have no precise idea why. I could get a valid list of packages by calling this function from Python3 in interactive mode. I have no time to create a minimal example which can raise that buggy behavior, I just suspect that is come from Python's internals. - here is attached a patch which provides the right list of packages as a hard-coded list. This list has been returned by the function listAllPackages() in interactive mode, and contains "pyqtgraph.widgets"; with that patch, the package is effective again. I propose a pull request for this patch, in Salsa. Best regards, Georges. -- Georges KHAZNADAR et Jocelyne FOURNIER 22 rue des mouettes, 59240 Dunkerque France. Téléphone +33 (0)3 28 29 17 70
