Many pytype errors when importing classes from collections.abc instead of typing in typeshed #1096
Description
In python/typeshed#6688, I attempted to change the typeshed stubs to import objects from collections.abc instead of typing wherever possible. However, a number of errors were output by pytype if the typeshed stubs were changed to import certain objects from collections.abc instead of typing. Most errors were related to Sequence, Callable and Iterable. However, there were also a number of errors that were simply AssertionError, with no other explanation.
Here is the full output of typeshed CI's pytype test, which can be found here . I would try to get a full stacktrace and/or narrow down the errors somewhat, but I'm on a Windows machine, so cannot run pytype, sadly:
Run ./tests/pytype_test.py
Testing files with pytype...
Run again with --print-stderr to get the full stacktrace.
