ModuleNotFoundError: No module named 'numpy.testing.nosetester'

I'm getting the following error:

Solution: Downgrade to numpy 1.16.4

sudo pip uninstall numpy
pip install numpy==1.16.4

[kaisark]

sudo pip3 uninstall numpy
sudo pip3 install numpy==1.16.4
sudo pip3 install scipy==1.1.0
sudo pip3 install scikit-learn==0.21.3

Of course, this package downgrade introduces a "ModuleNotFoundError: No module named 'sklearn.preprocessing._data'" error when running the Cursor_Control_Live_Demo.ipynb python notebook. A further downgrade of scikit-learn looks necessary.
