ChaiBapchya commented on issue #15768: Fix gradient tensor mutate in
`{adam/ftrl/rmprop/rmspropalex}_update`.
URL: https://github.com/apache/incubator-mxnet/pull/15768#issuecomment-578579407
So I tested *_update ops and it turns out passing randn (which samples from
uniform distribution) to *_update op (e.g. adam_update) gives output that may
consist nans
```
>
mx.nd.adam_update(mx.nd.random.randn(10),mx.nd.random.randn(10),mx.nd.random.randn(10),mx.nd.random.randn(10),.01)
[ nan nan 0.09059371 nan -0.1433481 nan
-0.5170411 0.381852 0.62985003 nan]
```
Now the way you've tested is checked if input and output has mutation after
*_update method is called. Does that take into consideration the NaNs?
