I was trying the tutorial in the following link. When I tried to load the image using topil() function, it resulted in the error - "ValueError: Size must be a tuple". I think this is because res1.dimensions is of type <class 'numpy.ndarray'> and Image.py expects it to be list or tuple. Please find below the traceback and the code.
