Dear Developers, I am a newbie on the TensorFlow business. I have however managed to install TensorFlow (macOS and metal) on M1 MacBook Air as detailed in this website (https://developer.apple.com/metal/tensorflow-plugin/) However, when I try to run an example code (https://github.com/keras-team/keras-io/blob/master/examples/vision/mnist_convnet.py), I got issues that I cannot understand `2021-08-01 00:28:43.807922: I tensorflow/compiler/mlir/mlir_graph_optimization_pass.cc:176] None of the MLIR Optimization Passes are enabled (registered 2) 2021-08-01 00:28:43.808097: W tensorflow/core/platform/profile_utils/cpu_utils.cc:128] Failed to get CPU frequency: 0 Hz Epoch 1/15 2021-08-01 00:28:43.911127: I tensorflow/core/grappler/optimizers/custom_graph_optimizer_registry.cc:112] Plugin optimizer for device_type GPU is enabled. 2021-08-01 00:28:43.984 python[20105:3940931] -[MPSNDArrayIdentity encodeToCommandEncoder:commandBuffer:sourceArrays:resultState:destinationArray:kernelDAGObject:]: unrecognized selector sent to instance 0x1682e8560 2021-08-01 00:28:43.987 python[20105:3940931] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MPSNDArrayIdentity encodeToCommandEncoder:commandBuffer:sourceArrays:resultState:destinationArray:kernelDAGObject:]: unrecognized selector sent to instance 0x1682e8560' *** First throw call stack: ( 0   CoreFoundation                      0x0000000180de2320 __exceptionPreprocess + 240 1   libobjc.A.dylib                     0x0000000180b10c04 objc_exception_throw + 60 2   CoreFoundation                      0x0000000180e71020 -[NSObject(NSObject) __retain_OA] + 0 3   CoreFoundation                      0x0000000180d44184 ___forwarding___ + 1444 4   CoreFoundation                      0x0000000180d43b30 _CF_forwarding_prep_0 + 96 5   libmetal_plugin.dylib               0x0000000150a55db4 ___ZN12metal_plugin14MPSApplyAdamOpIfE7ComputeEPNS_15OpKernelContextE_block_invoke.115 + 92 6   libdispatch.dylib                   0x0000000180abd420 _dispatch_client_callout + 20 7   libdispatch.dylib                   0x0000000180acba98 _dispatch_lane_barrier_sync_invoke_and_complete + 60 8   libmetal_plugin.dylib               0x0000000150a533c0 _ZN12metal_plugin14MPSApplyAdamOpIfE7ComputeEPNS_15OpKernelContextE + 4884 9   libmetal_plugin.dylib               0x0000000150a51e78 _ZN12metal_pluginL15ComputeOpKernelINS_14MPSApplyAdamOpIfEEEEvPvP18TF_OpKernelContext + 44 10  _pywrap_tensorflow_internal.so      0x0000000130076460 _ZN10tensorflow15PluggableDevice7ComputeEPNS_8OpKernelEPNS_15OpKernelContextE + 148 11  libtensorflow_framework.2.dylib     0x0000000123a78664 _ZN10tensorflow12_GLOBAL__N_113ExecutorStateINS_15PropagatorStateEE7ProcessENS2_10TaggedNodeEx + 3080 12  libtensorflow_framework.2.dylib     0x0000000123a79dbc _ZNSt3__110__function6__funcIZN10tensorflow12_GLOBAL__N_113ExecutorStateINS2_15PropagatorStateEE7RunTaskIZNS6_13ScheduleReadyEPN4absl14lts_2020_09_2313InlinedVectorINS5_10TaggedNodeELm8ENS_9allocatorISB_EEEEPNS5_20TaggedNodeReadyQueueEEUlvE0_EEvOT_EUlvE_NSC_ISL_EEFvvEEclEv + 56 13  _pywrap_tensorflow_internal.so      0x00000001307aa230 _ZN5Eigen15ThreadPoolTemplIN10tensorflow6thread16EigenEnvironmentEE10WorkerLoopEi + 1508 14  _pywrap_tensorflow_internal.so      0x00000001307a9b28 _ZZN10tensorflow6thread16EigenEnvironment12CreateThreadENSt3__18functionIFvvEEEENKUlvE_clEv + 80 15  libtensorflow_framework.2.dylib     0x0000000124014b08 _ZN10tensorflow12_GLOBAL__N_17PThread8ThreadFnEPv + 120 16  libsystem_pthread.dylib             0x0000000180c6a06c _pthread_start + 320 17  libsystem_pthread.dylib             0x0000000180c64da0 thread_start + 8 ) libc++abi.dylib: terminating with uncaught exception of type NSException` Do you have an idea what could be the reason? I would like also to benefit from GPU acceleration. I am running on macOS Big Sur 11.2.3. Many thanks, All the best
