When I try to run basically any CoreML model using MLPredictionOptions.outputBackings , inference throws the following error: 2024-09-11 15:36:00.184740-0600 run_demo[4260:64822] [coreml] Unrecognized ANE execution priority (null) 2024-09-11 15:36:00.185380-0600 run_demo[4260:64822] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unrecognized ANE execution priority (null)' *** First throw call stack: ( 0 CoreFoundation 0x000000019812cec0 __exceptionPreprocess + 176 1 libobjc.A.dylib 0x0000000197c12cd8 objc_exception_throw + 88 2 CoreFoundation 0x000000019812cdb0 +[NSException exceptionWithName:reason:userInfo:] + 0 3 CoreML 0x00000001a1bf6504 _ZN12_GLOBAL__N_141espressoPlanPriorityFromPredictionOptionsEP19MLPredictionOptions + 264 4 CoreML 0x00000001a1bf68c0 -[MLNeuralNetworkEngine _matchEngineToOptions:error:] + 236 5 CoreML 0x00000001a1be254c __62-[MLNeuralNetworkEngine predictionFromFeatures:options:error:]_block_invoke + 68 6 libdispatch.dylib 0x0000000197e20658 _dispatch_client_callout + 20 7 libdispatch.dylib 0x0000000197e2fcd8 _dispatch_l *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unrecognized ANE execution priority (null)' *** First throw call stack: ( 0 CoreFoundation 0x000000019812cec0 __exceptionPreprocess + 176 1 libobjc.A.dylib 0x0000000197c12cd8 objc_exception_throw + 88 2 CoreFoundation 0x000000019812cdb0 +[NSException exceptionWithName:reason:userInfo:] + 0 3 CoreML 0x00000001a1bf6504 _ZN12_GLOBAL__N_141espressoPlanPriorityFromPredictionOptionsEP19MLPredictionOptions + 264 4 CoreML 0x00000001a1bf68c0 -[MLNeuralNetworkEngine _matchEngineToOptions:error:] + 236 5 CoreML 0x00000001a1be254c __62-[MLNeuralNetworkEngine predictionFromFeatures:options:error:]_block_invoke + 68 6 libdispatch.dylib 0x0000000197e20658 _dispatch_client_callout + 20 7 libdispatch.dylib 0x0000000197e2fcd8 _dispatch_lane_barrier_sync_invoke_and_complete + 56 8 CoreML 0x00000001a1be2450 -[MLNeuralNetworkEngine predictionFromFeatures:options:error:] + 304 9 CoreML 0x00000001a1c9e118 -[MLDelegateModel _predictionFromFeatures:usingState:options:error:] + 776 10 CoreML 0x00000001a1c9e4a4 -[MLDelegateModel predictionFromFeatures:options:error:] + 136 11 libMLBackend_coreml.dylib 0x00000001002f19f0 _ZN6CoreML8runModelENS_5ModelERNSt3__16vectorIPvNS1_9allocatorIS3_EEEES7_ + 904 12 libMLBackend_coreml.dylib 0x00000001002c56e8 _ZZN8ModelImp9runCoremlEPN2ML7Backend17ModelIoBindingImpEENKUlvE_clEv + 120 13 libMLBackend_coreml.dylib 0x00000001002c1e40 _ZNSt3__110__function6__funcIZN2ML4Util10WorkThread11runInThreadENS_8functionIFvvEEEEUlvE_NS_9allocatorIS8_EES6_EclEv + 40 14 libMLBackend_coreml.dylib 0x00000001002bc3a4 _ZZN2ML4Util10WorkThreadC1EvENKUlvE_clEv + 160 15 libMLBackend_coreml.dylib 0x00000001002bc244 _ZNSt3__114__thread_proxyB7v160006INS_5tupleIJNS_10unique_ptrINS_15__thread_structENS_14default_deleteIS3_EEEEZN2ML4Util10WorkThreadC1EvEUlvE_EEEEEPvSC_ + 52 16 libsystem_pthread.dylib 0x0000000197fd32e4 _pthread_start + 136 17 libsystem_pthread.dylib 0x0000000197fce0fc thread_start + 8 ) libc++abi: terminating due to uncaught exception of type NSException Interestingly, if I don't use MLPredictionOptions to set pre-allocated output backings, then inference appears to run as expected. A similar issue seems to have been discussed and fixed here: https://developer.apple.com/forums/thread/761649 , however I'm seeing this issue on a beta build that I downloaded today (Sept 11 2024). Will this be fixed? Any advice would be greatly appreciated. Thanks
