samskalicky opened a new issue #13234: waitforall() hides errors
URL: https://github.com/apache/incubator-mxnet/issues/13234
 
 
   mx.nd.waitforall() doesnt check for errors and rethrow any that have occurred users will get an error when reading the output data. But I ran into an issue where I was gathering performance data, measuring elapsed time over an inference via model.forward() and mx.nd.waitforall() but I had hit an error and it was being hidden by waitforall(). I would have gotten the error had I actually read the output data, though. 
   
   For this issue, we should fix waitforall() to have the ability to check for errors on each of the outputs.
