Description
Is your feature request related to a problem? Please describe.
I used SaveImage(..., output_ext=".png")
but got this error message
monai.utils.module.OptionalImportError: No ImageWriter backend found for png.
This was after pip install monai
in a clean environment.
Describe the solution you'd like
It would be great if the error message would include a description of how to fix the issue, e..g. "Please install pillow". Initially I installed simpleitk which also didn't have the png writer apparently, and I got the same error.
Describe alternatives you've considered
n/a
Additional context
Happened with monai==1.3.2
