Description

master branch contains many fixes for various numpy operators included in the 1.7 release. While they are experimental in 1.7, it would be helpful to include the fixes. For example, I tested running GluonNLP NumPy version with the 1.7 branch and some unittests are failing.

For example, MXNetError: Operator _npi_unique is non-differentiable because it didn't register FGradient attribute which was fixed in #18074 is not part of 1.7

To fix this issue, one could copy over all numpy operator related C++ and Python files from the master branch to the 1.x and 1.7 branches.
