Environment

• Pythonnet version: 2.5.1
• Python version: 3.7.9
• Operating System: Windows 10

Details

• Describe what you were trying to get done.

pythonnet overwrites the python's__import__ routine, but does not implement python's signature precisely:
original python's signature is

__import__(name,globals=None,locals=None,fromlist=(),level=0)

Most other python modules call the name parameter as positional:__import__("foo", ...

Some packages (e.g. kivy) use__import__ as

__import__(name='{2}.{0}.{1}'.format(basemodule,modulename,base),globals=globals(),locals=locals(),fromlist=[modulename],level=0    )

i.e. the name argument used as keyword argument in the call. Both calls are valid in python's__import__, but fail at the overwritten__import__ with

TypeError:__import__()takesatleast1argument (0given)

A hotfix is to alter the other modules code to

__import__('{2}.{0}.{1}'.format(basemodule,modulename,base),globals=globals(),locals=locals(),fromlist=[modulename],level=0    )

but the broken code is within pythonnet.
