ITK TypeError - resolved by updating ITK

[nkrah]

For info:
test058_calc_uncertainty_MT.py was failing because of a TypeError raised by ITK. Specifically:
TypeError: in method 'itkImageIOFactory_CreateImageIO', argument 1 of type 'char const *'

After updating ITK (via pip) from 5.2.1.post1 to 5.3.0, the error is gone.

If you get a similar error, try updating ITK first, by
pip install itk --upgrade
