All links for NDArray in the Python documentation link to mxnet.optimizer.NDArray instead of mxnet.ndarray.NDArray. Could add confusion for users, since this is the wrong reference to NDArray. And it's only technically possible because NDArray is imported in optimizer.py.

• See https://mxnet.incubator.apache.org/api/python/ndarray/ndarray.html#mxnet.ndarray.save for an example.
• Under 'Parameters', 'data', click on 'NDArray'
• Goes (incorrectly) to https://mxnet.incubator.apache.org/api/python/optimization/optimization.html#mxnet.optimizer.NDArray
