root: INFO: NumPy-shape semantics has been activated in your code. This is required for creating and manipulating scalar and zero-size tensors, which were not supported in MXNet before, as in 

the official NumPy library. Please DO NOT manually

 deactivate this semantics while using `mxnet.numpy` and `mxnet.numpy_extension` modules.
