crashed when running coreml batch prediction from background to foreground
this is my code:
id<MLBatchProvider> outBatch = [_model predictionsFromBatch:inBatch options:options error:error];
When the app is in the foreground， I submitted the batch predictions, Then I put the app in to background, and next I put the app to the foreground, the app is crashed.
the crash is :

What happens when you force the prediction to run on the CPU (you can specify that in youroptionsargument), does it still crash? Note that iOS apps cannot use the GPU while they are in the background.
