High error when evaluate mode with importNetworkFromPyTorch

Hi Matlab community,

I've built a simple regression model with pyTorch, and saved it to 'model.pt'. Then, I import it using importNetworkFromPyTorch and initialize with train data.

inputData = X_train';
dlX = dlarray(inputData, 'CB');
net = initialize(net, dlX); 

After having the net file, I added it Predict Block in simulink here: Predict

The result for regression is not good compare to result that I validate with python. I don't know if I did anything wrong here.

What happens when we initialize the network? do we need to use train data to set correct weights? Looking forward to hearing from you
