If the inputs uses float16, shouldn't there be a dtype switch (float16 ->
float32) before `BatchNormForward`?
https://github.com/apache/incubator-mxnet/blob/b6972bb055fc44481b072db3abb90e26ee27c787/src/operator/nn/batch_norm-inl.h#L292
Why would this type mismatch error still exist?
`Check failed: (*in_type)[i] == dtype_param (2 vs. 0) : This layer requires
uniform type. Expected 'float32' v.s. given 'float16' at 'gamma'`
