I am trying to import a model from Keras to MATLAB. I am unable to create the variable containing the model.
modelfile = '4k_mag_run1.h5';
net =importKerasNetwork(modelfile, 'WeightFile', modelfile,'ImageInputSize',[256,256]);
The model is a version of the UNet model which I have trained myself and is being used for semantic segmentation.
The error message recieved is:
Error using importKerasNetwork (line 94)
The value of 'TrainedVariance' is invalid. Expected input to be positive.
Error in Classify_LT (line 3)
net =importKerasNetwork(modelfile, 'WeightFile', modelfile,'ImageInputSize',[256,256]);

Hello,
If your "modelfile" contains the weights of the model then there is no need to pass "WeightFile" as parameter to the "importKerasNetwork" funtion else your weights for the model should be in different file.
Please refere to "Name-Value Pair Arguments" section in the article
