apeforest opened a new issue #14137: [Feature Request] turning off cudnn autotune
URL: https://github.com/apache/incubator-mxnet/issues/14137
 
 
   Current document says: 
   
   > Running performance tests to find the best convolution algorithm, this can take a while... (setting env variable MXNET_CUDNN_AUTOTUNE_DEFAULT to 0 to disable)
   
   However, if in the convolution layer of the model, cudnn_tune is set, this environment variable will not take any effect causing unexpected result from user. 
   
   We need to let this variable have global control, or remove the cudnn_tune param per convolution layer altogether (I personally don't understand why we had it there in the first place)
