Using a context manager to ignore
ImportWarning
during module imports also prevents libraries setting warning filters (such as NumPy) from being persistent, since the filters they set are discarded when exiting the context manager.I might be missing something, but it seems the usage of this context manager to ignore such warnings is redundant with the default warning filters installed by Python.
