zixuanweeei opened a new pull request #15497: Independent gradients requests check with respect to weights and bias of convolution
URL: https://github.com/apache/incubator-mxnet/pull/15497
 
 
   ## Description ##
   As it was described in #15464, MXNet with MKL-DNN gives a wrong gradient of a convolution with respect to its biases unless the gradient with respect to its weights is also requested. It should be checked independently.
   
   ## Checklist ##
   ### Changes ###
   - [x] Independently check the requests for gradients with respect to weights and bias of convolution.
   - [x] Convolution can give the gradient with respect to any one of weights or bias.
