It would be fairly simple to separate out the numpy operators to create a NumPy API: https://medium.com/apache-mxnet/a-new-numpy-interface-for-apache-mxnet-incubating-dbb4a4096f9f? For the full experience #2 would need to be addressed.

Implement advanced indexing -- support indexing by array or ndarray of indices. Currently only basic indexing is supported: `NewAxis`, slicing and stepping with `SliceRange` obj. https://github.com/apache/incubator-mxnet/blob/7713a43353b06b91ae7d5d508868b42ce557e487/python/mxnet/ndarray/ndarray.py#L1265
