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

Xcode Version: Version 15.2 (15C500b) com.github.apple.coremltools.source: torch==1.12.1 com.github.apple.coremltools.version: 7.2 Compute: Mixed (Float16, Int32) Storage: Float16 The input to the mlpackage is MultiArray (Float16 1 × 1 × 544 × 960) The flexibility is: 1 × 1 × 544 × 960 | 1 × 1 × 384 × 640 | 1 × 1 × 736 × 1280 | 1 × 1 × 1088 × 1920 I tested this on iPhone XR, iPhone 11, iPhone 12, iPhone 13, and iPhone 14. On all devices except the iPhone 11, the model runs correctly on the NPU. However, on the iPhone 11, the model runs on the CPU instead. Here is the CoreMLTools conversion code I used: mlmodel = ct.convert(trace, inputs=[ct.TensorType(shape=input_shape, name="input", dtype=np.float16)], outputs=[ct.TensorType(name="output", dtype=np.float16, shape=output_shape)], convert_to='mlprogram', minimum_deployment_target=ct.target.iOS16 )

func testMLTensor() { let t1 = MLTensor(shape: [2000, 1], scalars: [Float](repeating: Float.random(in: 0.0...10.0), count: 2000), scalarType: Float.self) let t2 = MLTensor(shape: [1, 3000], scalars: [Float](repeating: Float.random(in: 0.0...10.0), count: 3000), scalarType: Float.self) for _ in 0...50 { let t = Date() let x = (t1 * t2) print("MLTensor", t.timeIntervalSinceNow * 1000, "ms") } } testMLTensor() The above code took more time than expected, especially in the early stage of iteration.

All errors in TranslationError return the same error code, making it difficult to differentiate between them. How can this issue be resolved?

I have created and trained a Hand Pose classifier model and am trying to test it. I have noticed in the WWDC2021 "Classify hand poses and actions with Create ML" the preview windows has a prediction result that gives you the prediction based on the live preview or the images. Mine does not have that. When i try to import pictures or do the live test there is no result. Its just the wireframe view and under it there is nothing. How do I fix this please? Thanks.

Hi, the following model does not run on ANE. Inspecting with deCoreML I see the error ane: Failed to retrieved zero_point. import numpy as np import coremltools as ct from coremltools.converters.mil import Builder as mb import coremltools.converters.mil as mil B, CIN, COUT = 512, 1024, 1024 * 4 @mb.program( input_specs=[ mb.TensorSpec((B, CIN), mil.input_types.types.fp16), ], opset_version=mil.builder.AvailableTarget.iOS18 ) def prog_manual_dequant( x, ): qw = np.random.randint(0, 2 ** 4, size=(COUT, CIN), dtype=np.int8).astype(mil.mil.types.np_uint4_dtype) scale = np.random.randn(COUT, 1).astype(np.float16) offset = np.random.randn(COUT, 1).astype(np.float16) # offset = np.random.randint(0, 2 ** 4, size=(COUT, 1), dtype=np.uint8).astype(mil.mil.types.np_uint4_dtype) dqw = mb.constexpr_blockwise_shift_scale(data=qw, scale=scale, offset=offset) return mb.linear(x=x, weight=dqw) cml_qmodel = ct.convert( prog_manual_dequant, compute_units=ct.ComputeUnit.CPU_AND_NE, compute_precision=ct.precision.FLOAT16, minimum_deployment_target=ct.target.iOS18, ) Whereas if I use an offset with the same dtype as the weights (uint4 in this case), it does run on ANE Tested on coremltools 8.0b1, on macOS 15.0 beta 2/Xcode 15 beta 2, and macOS 15.0 beta 3/Xcode 15 beta 3.

I‘ve created text classification project and selected BERT algorithm With 100 iterations for json file. Json file is valid but training always cancels on 37 iteration… Because tool does not provide any cancellation reasons I have no clue why it happens. Can I check reasons somehow? Or do anyone knows possible reasons or solutions for this?

Hi everyone, I attempted to use the MultivariateLinearRegressor from the Create ML Components framework to fit some multi-dimensional data linearly (4 dimensions in my example). I aim to obtain multi-dimensional output points (2 points in my example). However, when I fit the model with my training data and test it, it appears that only the first element of my training data is used for training, regardless of whether I use CreateMLComponents.AnnotatedBatch or [CreateMLComponents.AnnotatedFeature, CoreML.MLShapedArray>] as input. let sourceMatrix: [[Double]] = [ [0,0.1,0.2,0.3], [0.5,0.2,0.6,0.2] ] let referenceMatrix: [[Double]] = [ [0.2,0.7], [0.9,0.1] ] Here is a test code to test the function (ios 18.0 beta, Xcode 16.0 beta) In this example I train the model to learn 2 multidimensional points (4 dimensions) and here are the results of the predictions: ▿ 2 elements ▿ 0 : AnnotatedPrediction<MLShapedArray<Double>, MLShapedArray<Double>> ▿ prediction : 0.20000000298023224 0.699999988079071 ▿ _storage : <StandardStorage<Double>: 0x600002ad8270> ▿ annotation : 0.2 0.7 ▿ _storage : <StandardStorage<Double>: 0x600002b30600> ▿ 1 : AnnotatedPrediction<MLShapedArray<Double>, MLShapedArray<Double>> ▿ prediction : 0.23158159852027893 0.9509953260421753 ▿ _storage : <StandardStorage<Double>: 0x600002ad8c90> ▿ annotation : 0.9 0.1 ▿ _storage : <StandardStorage<Double>: 0x600002b55f20> 0.23158159852027893 0.9509953260421753 is totally random and should be far more closer to [0.9,0.1].

I have made a text classifier model but I want to train it on device too. When text is classified wrong, user can make update the model on device.

I have several CoreML models that I've set up to run in sequence where one of the outputs from each model is passed as one of the inputs to the next. For the most part, there is very little overhead in between each sub-model "chunk": However a couple of the models (eg the first two above) spend a noticeable amount of time in "Prepare Neural Engine Request". From Instruments, it seems like this is spent doing some sort of model loading. Given that I'm calling these models in sequence and in a fixed order, is there some way to reduce or amortize this cost? Thanks!

I was trying the latest coremltools-8.0b1 beta on macOS 15 Beta with the intent to try using the new stateful models api in CoreML. But the conversion would always fail with the error: /AppleInternal/Library/BuildRoots/<snip>/Library/Caches/com.apple.xbs/Sources/MetalPerformanceShadersGraph/mpsgraph/MetalPerformanceShadersGraph/Core/Files/MPSGraphExecutable.mm:162: failed assertion `Error: the minimum deployment target for macOS is 14.0.0' Here's a minimal repro, which works fine with both the stable version of coremltools (7.2) and the beta version (8.0b1) on macOS Sonoma 14.5, but fails with both versions of coremltools on macOS 15.0 Beta and Xcode 16.0 Beta. Which means that this most likely isn't an issue with coremltools, but with the native compilation toolchain. from collections import OrderedDict import coremltools as ct import numpy as np import torch import torch.nn as nn class ResidualAttentionBlock(nn.Module): def __init__(self, d_model: int, n_head: int, attn_mask: torch.Tensor = None): super().__init__() self.attn = nn.MultiheadAttention(d_model, n_head) self.ln_1 = nn.LayerNorm(d_model) self.mlp = nn.Sequential( OrderedDict( [ ("c_fc", nn.Linear(d_model, d_model * 4)), ("gelu", nn.GELU()), ("c_proj", nn.Linear(d_model * 4, d_model)), ] ) ) self.ln_2 = nn.LayerNorm(d_model) self.attn_mask = attn_mask def attention(self, x: torch.Tensor): self.attn_mask = ( self.attn_mask.to(dtype=x.dtype, device=x.device) if self.attn_mask is not None else None ) return self.attn(x, x, x, need_weights=False, attn_mask=self.attn_mask)[0] def forward(self, x: torch.Tensor): x = x + self.attention(self.ln_1(x)) x = x + self.mlp(self.ln_2(x)) return x class Transformer(nn.Module): def __init__( self, width: int, layers: int, heads: int, attn_mask: torch.Tensor = None ): super().__init__() self.width = width self.layers = layers self.resblocks = nn.Sequential( *[ResidualAttentionBlock(width, heads, attn_mask) for _ in range(layers)] ) def forward(self, x: torch.Tensor): return self.resblocks(x) transformer = Transformer(width=512, layers=12, heads=8) emb_tokens = torch.rand((1, 512)) ct_model = ct.convert( torch.jit.trace(transformer.eval(), emb_tokens), convert_to="mlprogram", minimum_deployment_target=ct.target.macOS14, inputs=[ct.TensorType(name="embIn", shape=[1, 512])], outputs=[ct.TensorType(name="embOutput", dtype=np.float32)], )

I want to try an any resolution image input Core ML model. So I wrote the model following the Core ML Tools "Set the Range for Each Dimensionas" sample code, modified as below: # Trace the model with random input. example_input = torch.rand(1, 3, 50, 50) traced_model = torch.jit.trace(model.eval(), example_input) # Set the input_shape to use RangeDim for each dimension. input_shape = ct.Shape(shape=(1, 3, ct.RangeDim(lower_bound=25, upper_bound=1920, default=45), ct.RangeDim(lower_bound=25, upper_bound=1920, default=45))) scale = 1/(0.226*255.0) bias = [- 0.485/(0.229) , - 0.456/(0.224), - 0.406/(0.225)] # Convert the model with input_shape. mlmodel = ct.convert(traced_model, inputs=[ct.ImageType(shape=input_shape, name="input", scale=scale, bias=bias)], outputs=[ct.TensorType(name="output")], convert_to="mlprogram", ) # Save the Core ML model mlmodel.save("image_resize_model.mlpackage") It converts OK but when I predict the result with an image It will get the error as below: You will not be able to run predict() on this Core ML model. Underlying exception message was: { NSLocalizedDescription = "Failed to build the model execution plan using a model architecture file '/private/var/folders/8z/vtz02xrj781dxvz1v750skz40000gp/T/model-small.mlmodelc/model.mil' with error code: -7."; } Where did I do wrong?

I'm looking for a solution to take a picture or point the camera at a piece of clothing and match that image with an image the user has stored in my app. I'm storing the data in a Core Data database as a Binary Data object. Since the user also takes the pictures they store in the database I think I cannot use pre-trained Core ML models. I would like the matching to be done on device if possible instead of going to an external service. That will probably describe the item based on what the AI sees, but then I cannot match the item with the stored images in the app. Does anyone know if this is possible with frameworks as Vision or VisionKit?

Deploy machine learning and AI models on-device with Core ML say the performance report can see the ops run on which unit and why it cannot run on Neural Engine. I tested my model and the report shows a gray checkmark at the Neural Engine, indicating it can run on the Neural Engine. However, it's not executing on the Neural Engine but on the CPU. Why is this happening?

I have a couple of models that I want to migrate to .mlpackage but can not find the resources of the session: https://developer.apple.com/videos/play/wwdc2024/10159/ In the video at 21:10 talk about modifications and optimizations, but in the video can not even see the dependencies of the demo. Thanks

I have created a Hand Action Classification project following the guidelines which causes the Create ML tool to provide the very cryptic "Unexpected Error". The feature extraction phase is fine, with the error occurring during model training after the tool reports completion of the first five training iterations as it moves on to report the next ten. The project is small with 3 training classes and 346 items I have tried to vary the frame rate and action duration, with all augmentations unset, but the error still persists. Can you please confirm how I may get further error diagnostic information so that I can determine why Create ML is unable to work with my training data? Mac OS is Sonoma 14.5 on an iMac 24-inch, M1, 2021. Create ML is Version 5.0 (121.4)

Hi there, I am trying to create a Message Filter app that uses a trained Text Classification to predict scam texts (as it is common in my country and is constantly evolving). However, when I try to use the MLModel in the MessageFilterExtension class, I'm getting initialization of text classifier model with model data failed Here's how I initialize my MLModel that is created using Create ML. do { let model = try MyModel(configuration: .init()) let output = try model.prediction(text: text) guard !output.label.isEmpty else { return nil } return MessagePrediction(rawValue: output.label) } catch { return nil } Is it impossible to use CoreML in Message Filter extensions? Thank you
