TaoLv edited a comment on issue #13362: Add NHWC layout support to Pooling (cuDNN only)
URL: https://github.com/apache/incubator-mxnet/pull/13362#issuecomment-444771242
 
 
   Tested this PR on CPU w/ and w/o MKL-DNN  and got error message as below.
   w/o MKL-DNN:
   ```
   Traceback (most recent call last):

       out_nhwc = mx.nd.Pooling(data=inp_nhwc, kernel=kernel, pool_type='max', global_pool=False, stride=stride, pad=pad, layout='NHWC')

   ```
   w/ MKL-DNN:
   ```
   terminate called after throwing an instance of 'dmlc::Error'
     what():  [12:28:11] src/engine/./threaded_engine.h:380: std::exception
   A fatal error occurred in asynchronous engine operation. If you do not know what caused this error, you can try set environment variable MXNET_ENGINE_TYPE to NaiveEngine and run with debugger (i.e. gdb). This will force all operations to be synchronous and backtrace will give you the series of calls that lead to this error. Remember to set MXNET_ENGINE_TYPE back to empty after debugging.
