Steps to reproduce

or if you are running standard examples, please provide the commands you have run that lead to the error.

1. just run python custom_softmax.py

What have you tried to solve it?

1. I found that I can not do save or bind on this mlp model, such as mlp.save('x.json'). It works only on mlp=mx.symbol.softmax(data = fc3, name = 'softmax')
2. I write a simple code to use this custom operator. The program crashed when I tried to do any computation or saving on the model. Only build-in softmax works.
