The original run through with 2000 image and 5 epochs imports as an "h5" file and can run inference, but when I re-import into keras and retrain for another 3 epochs, when I try to import the h5 file back into MATLAB, I get the following error:
Error using importKerasNetwork (line 94)
Expected input to be positive.
Error in test (line 1)
LFUNET = importKerasNetwork('model_next.h5');
What exactly does this error mean? I'm not very sure what is means that my h5 file is negative. These files are much larger than
