Save the image results of the test

[yandszzz]

Hello author, thank you for your contribution to the pansharpening deep learning toolbox. When I was running run_test_manshharpening. py, the saved test result (i.e. the fused image file) was empty. How can I set it to correctly save the fused image file?

You need to debug and modify the val_step() function in the base_model.py file, as there is a bug present.
