Difference in naming convention between op.py and test_op.py

[AetherPrior]

Description

Mxnet's NumPy is being imported as np in the file src/gluonnlp/op.py:

gluon-nlp/src/gluonnlp/op.py

Line 8 in 5d4bc9e

from mxnet import np, npx

While NumPy is imported as np in test_op.py:

gluon-nlp/tests/test_op.py

Line 1 in 5d4bc9e

import numpy as np

This requires a change in conventions between tests and code, which can be a minor nuisance.

What have you tried to solve it?

1. While a simple refactoring is possible, I don't want to be reverting any design decision in any way.
