Jessespace opened a new issue #14220: Qestion bout nd.waitall()
URL: https://github.com/apache/incubator-mxnet/issues/14220
 
 
   I want to test the inference time about yolov3.I I wrote two versions.like bellow:
   
   1.`tic = time.time()
   class_IDs, scores, bounding_boxs = net(x)
   toc = time.time()
   print("Inference time is :",toc-tic)`
   
   2.`tic = time.time()
   class_IDs, scores, bounding_boxs = net(x)
   **nd.waitall()**
   toc = time.time()
   print("Inference time is :",toc-tic)`
   
   The results of the two versions vary greatly.Which one is right? and Why?
