error : The import of 'collections.abc' is forbidden

Question

By testing my solutioin to the homework5 five I get this error, but I don't understand why, as I imported only the images module.

FAILED test_01.py::Test::test_data_01___1___1080_ - testlib.ForbiddenError: The import of 'collections.abc' is forbidden
...

What does that module do? What is it for?

Answer 1

Does it give you the error both locally and on the VM? I think it's a library loaded by tests to report an error. Try running the function directly and see if it gives you an error.

Answer 2

I am pretty much sure that, the issue is with the testfiles/png module/images module. I ran the tests in an empty file with only the images module imported and it threw the same error you mentioned. But the error was gone when I removed the import images.

One way to fix this is to edit test01.py and adding 'collections.abc' in self.check_imports() [Line 31] along with other allowed imports. But I wouldn't really suggest you to edit the test files.
