Thanks for the quick response.
I’m sorry, I think I’ve explained myself in a wrong way. All my images have the same size, I meant that running the same code with images with other sizes make it to fail. But if the images are bigger than 48x48, it fails.
Do you know if a resizing is automatically done depending on the input size? For instance, for sizes smaller or equal than 48, it is done, whereas for higher than 48 it isn’t.
Many thanks in advance!
