   @xiaodao2049 : I think the reason is that there are multiple implementations of convolution when using cundd  and cudnn chooses the best algorithm based on your available system resources at runtime. You could try using "MXNET_ENFORCE_DETERMINISM" (Refer [this PR](https://github.com/apache/incubator-mxnet/pull/12992) for full context) and see if this helps. If not you could turn off autotune by setting "MXNET_CUDNN_AUTOTUNE_DEFAULT" to 0 and see if that helps. 
   
   @apeforest , please correct me if any part of my answer is misrepresented :) 
   
   @mxnet-label-bot add [question, cudnn]
