eric-haibin-lin opened a new issue #7346: [OP] Input gamma mutated in Batch Norm
URL: https://github.com/apache/incubator-mxnet/issues/7346
 
 
   In BatchNorm operator, gamma is not listed as `aux_data` in backend, but actually mutated when `fix_gamma` is True. For sparse storage fallback, when a dense executors see a mutable sparse input, it will generate a dense copy, execute fcompute, and convert the mutated dense copy back to source NDArray. For BatchNorm gamma is not listed as mutable inputs, so storage fallback will not convert this input back to sparse NDArray and fail.
   
   We should use temp storage when `fix_gamma == True` instead of changing input. Need to fix it for #7082
