azure-cognitiveservices-nspkg has not been converted to implicit namespaces (PEP 420) #4461
Description
I am currently working on updating the Python Azure SDK in openSUSE/SLE to the latest upstream version. This involves switching over the packaging to adopt to the move to implicit namespace packages (PEP 420).
This has worked fine with azure-nspkg and azure-mgmt-nspkg so far, but azure-cognitiveservices-nspkg still behaves like the old namespace packages compiles and installs the __init__.py files.
Thus, the RPM builds complains that the namespace directories are not empty as they should after switching to implicit namespace packages for Python 3.7:
