Description

File "/home/jenkins/agent/workspace/MONAI-premerge/monai/monai/transforms/utils.py", line 167, in rescale_array

    norm = (arr - mina) / (maxa - mina)  # normalize the array first

RuntimeError: Integer division of tensors using div or / is no longer supported, and in a future release div will perform true division as in Python 3. Use true_divide or floor_divide (// in Python) instead.
