I'm using Numbers to build a spreadsheet that I'm exporting as a CSV. I then import this file into Create ML to train a word tagger model. Everything has been working fine for all the models I've trained so far, but now I'm coming across a use case that has been breaking the import process: commas within the training data. This is a case that none of Apple's examples show. My project takes Navajo text that has been tokenized by syllables and labels the parts-of-speech. Case that works... Raw text: Naaltsoos yídéeshtah. Tokens column: Naal,tsoos, ,yí,déesh,tah,. Labels column: NObj,NObj,Space,Verb,Verb,VStem,Punct Case that breaks... Raw text: óola, béésh łigaii, tłʼoh naadą́ą́ʼ, wáin, akʼah, dóó á,shįįh Tokens column with tokenized text (commas quoted): óo,la,",", ,béésh, ,łi,gaii,",", ,tłʼoh, ,naa,dą́ą́ʼ,",", ,wáin,",", ,a,kʼah,",", ,dóó, ,á,shįįh (Create ML reports mismatched columns) Tokens column with tokenized text (commas escaped): óo,la,\,, ,béésh, ,łi,gaii,\,, ,tłʼoh, ,naa,dą́ą́ʼ,\,, ,wáin,\,, ,a,kʼah,\,, ,dóó, ,á,shįįh (Create ML reports mismatched columns) Tokens column with tokenized text (commas escape-quoted): óo,la,\",\", ,béésh, ,łi,gaii,\",\", ,tłʼoh, ,naa,dą́ą́ʼ,\",\", ,wáin,\",\", ,a,kʼah,\",\", ,dóó, ,á,shįįh (record not detected by Create ML) Tokens column with tokenized text (commas escape-quoted): óo,la,"","", ,béésh, ,łi,gaii,"","", ,tłʼoh, ,naa,dą́ą́ʼ,"","", ,wáin,"","", ,a,kʼah,"","", ,dóó, ,á,shįįh (Create ML reports mismatched columns) Labels column: NSub,NSub,Punct,Space,NSub,Space,NSub,NSub,Punct,Space,NSub,Space,NSub,NSub,Punct,Space,NSub,Punct,Space,NSub,NSub,Punct,Space,Conj,Space,NSub,NSub Sample From Spreadsheet Solution Needed It's simple enough to escape commas within CSV files, but the format needed by Create ML essentially combines entire CSV records into single columns, so I'm ending up needing a CSV record that contains a mixture of commas to use for parsing and ones to use as character literals. That's where this gets complicated. For this particular use case (which seems like it would frequently arise when training a word tagger model), how should I properly escape a comma literal?

iOS 18.2 includes a new feature called Visual Intelligence. If I hold down the Camera Control on my iPhone, I can take a photo of an object and use Google to look up items similar to what I've photographed. Is there a way to programmatically open this interface within my app? If so, can I see which result the user selects?

I am trying to create a Pipeline with 3 sub-models: a Feature Vectorizer -> a NN regressor converted from PyTorch -> a Feature Extractor (to convert the output tensor to a Double value). The pipeline works fine when I use just a Vectorizer and an Extractor, this is the code: vectorizer = models.feature_vectorizer.create_feature_vectorizer( input_features=["windSpeed", "theoreticalPowerCurve", "windDirection"], # Multiple input features output_feature_name="input" ) preProc_spec = vectorizer[0] ct.utils.convert_double_to_float_multiarray_type(preProc_spec) extractor = models.array_feature_extractor.create_array_feature_extractor( input_features=[("input",datatypes.Array(3,))], # Multiple input features output_name="output", extract_indices = 1 ) ct.utils.convert_double_to_float_multiarray_type(extractor) pipeline_network = pipeline.PipelineRegressor ( input_features = ["windSpeed", "theoreticalPowerCurve", "windDirection"], output_features=["output"] ) pipeline_network.add_model(preProc_spec) pipeline_network.add_model(extractor) ct.utils.convert_double_to_float_multiarray_type(pipeline_network.spec) ct.utils.save_spec(pipeline_network.spec,"Final.mlpackage") This model works ok. I created a regression NN using PyTorch and converted to Core ML either import torch import torch.nn as nn class TurbinePowerModel(nn.Module): def __init__(self): super().__init__() self.linear1 = nn.Linear(3, 4) self.activation1 = nn.ReLU() #self.linear2 = nn.Linear(5, 4) #self.activation2 = nn.ReLU() self.output = nn.Linear(4, 1) def forward(self, x): #x = F.normalize(x, dim = 0) x = self.linear1(x) x = self.activation1(x) # x = self.linear2(x) # x = self.activation2(x) x = self.output(x) return x def forward_inference(self, windSpeed,theoreticalPowerCurve,windDirection): input_tensor = torch.tensor([windSpeed, theoreticalPowerCurve, windDirection], dtype=torch.float32) return self.forward(input_tensor) model = torch.load('TurbinePowerRegression-1layer.pt', weights_only=False) import coremltools as ct print(ct.__version__) import pandas as pd from sklearn.preprocessing import StandardScaler df = pd.read_csv('T1_clean.csv',delimiter=';') X = df[['WindSpeed','TheoreticalPowerCurve','WindDirection']] y = df[['ActivePower']] scaler = StandardScaler() X = scaler.fit_transform(X) y = scaler.fit_transform(y) X_tensor = torch.tensor(X, dtype=torch.float32) y_tensor = torch.tensor(y, dtype=torch.float32) traced_model = torch.jit.trace(model, X_tensor[0]) mlmodel = ct.convert( traced_model, inputs=[ct.TensorType(name="input", shape=X_tensor[0].shape)], classifier_config=None # Optional, for classification tasks ) mlmodel.save("TurbineBase.mlpackage") This model has a Multiarray(Float 32 3) as input and a Multiarray(Float32 1) as output. When I try to include it in the middle of the pipeline (Adjusting the output and input types of the other models accordingly), the process runs ok, but I have the following error when opening the generated model on Xcode: What's is missing on the models. How can I set or adjust this metadata properly? Thanks!!!

Hi everyone, I’m currently using macOS Version 15.3 Beta (24D5034f), and I’m encountering an issue with Apple Intelligence. The image generation tools seem to work fine, but everything else shows a message saying that it’s “not available at this time.” I’ve tried restarting my Mac and double-checked my settings, but the problem persists. Is anyone else experiencing this issue on the beta version? Are there any fixes or settings I might be overlooking? Any help or insights would be greatly appreciated! Thanks in advance!

there was a beta version. after the update it worked just like regular Siri. this message has been there for two days now but there is no loading.

Hey I have a macbook pro M1 and I don't understand why but the download of apple intelligence since macOS 15.2 is remaining block at 100% with the same message telling me to be plug and connect to a network

I've implemented the imagePlaygroundSheet modifier in my app. It eventually all works but I've consistently noticed that the first time I present it, the sheet is totally blank. I then have to pull down to dismiss it (it doesn't even have a cancel button) and present it a second time and it loads content. Just me? This is on 18.2 final, iPhone 16 Pro Max.

After updating to macOS15.2beta, the Yolo11 object detection model exported to coreml outputs incorrect and abnormal bounding boxes. It also doesn't work in iOS apps built on a 15.2 mac. The same model worked fine on macOS14.1. When training a Yolo11 custom model in Python, exporting it to coreml, and testing it in the preview tab of mlpackage on macOS15.2 and Xcode16.0, the above result is obtained.

Howdy, I'm following along with this sample: https://developer.apple.com/documentation/appintents/making-onscreen-content-available-to-siri-and-apple-intelligence I've got everything up and building. I can confirm that the userActivity modifier is associating my App Intent via EntityIdentifier but my custom Transferable representation (text) is never being called and when Siri is doing the ChatGPT handoff, it's just offering to send a screenshot which is what it does when it has no custom representation. What could I doing wrong? Where should I be looking?

I have an issue with AI writing tools, certain applications, such as LinkedIn, function effectively, while others, like Instagram and WhatsApp, lack the writing tools option.

Hi everyone, On the "Apple Intelligence & Siri" settings there's a section titled "Extensions" that specifically mentions ChatGPT. This got me curious—does Apple provide an API or SDK for developers to create custom integrations or use Apple Intelligence Extensions? Or is this currently limited to the Apple/OpenAI partnership? I appreciate any insights or links to relevant documentation. Here's a screenshot of what I mean: https://imgur.com/a/4MuQkIJ

Alguem me pode indicar se os devolopers que estão no espaço da união europeia, possam aceder aos serviços apple intelligence ? Obrigado

We use MLModel in our app, which uses two file formats: mlmodel and mlpackage. We find that when the model is released, models using mlmodel format have a certain probability of crashing.

I want to get depth map that when camera zoom in or zoom out or switch to telephoto. I have got the depth map using ARkit that provide depth map that the colored RGB image from the wide-range camera and the depth ratings from the LiDAR scanner are fused together. Now I want to switch camera to telephoto and hope to get new depth map.

FB:FB16079804 Hello, I've made the FastAI's Cat vs Dog model into model that distinguishes lemons from limes and it all works fine in a notebook. I am now looking to transform this model into Core ML for my iOS app using TorchScript and Apple official guidelines for coremltools. Model converts but I cannot see the Preview Tab in. Xcode. Have anyone of you tried to convert to Core ML? I guess my input types are not matching with coremltools expectations for preview but I am stuck . Here is my code. import torch import coremltools as ct from fastai.vision.all import * import json from torchvision import transforms # Load your Fastai model (replace with your actual path) learn = load_learner('lemonmodel.pkl') # Example input image (you can use any image from your dataset) input_image = PILImage.create('example.jpg') # Preprocess the image (assuming you used these transforms during training) to_tensor = transforms.ToTensor() normalize = transforms.Normalize(mean=[0.485, 0.456, 0.406], std=[0.229, 0.224, 0.225]) input_tensor = to_tensor(input_image) input_tensor = normalize(input_tensor) # Apply normalization # Add a batch dimension input_tensor = input_tensor.unsqueeze(0) # Ensure float32 type input_tensor = input_tensor.float() # Trace the model trace = torch.jit.trace(learn.model, input_tensor) # Define the Core ML input type (considering your model's input shape) _input = ct.ImageType( name="input_1", shape=input_tensor.shape, bias=[-0.485/0.229, -0.456/0.224, -0.406/0.225], scale=1./(255*0.226) ) # Convert the model to Core ML format mlmodel = ct.convert( trace, inputs=[_input], minimum_deployment_target=ct.target.iOS14 # Optional, set deployment target ) # Set model type as 'imageClassifier' for the Preview tab mlmodel.type = 'imageClassifier' # Correct structure for preview parameters** (assuming two classes: 'lemon' and 'lime') labels_json = { "imageClassifier": { "labels": ["lemon", "lime"], "input": { "shape": list(input_tensor.shape), # Provide the actual input shape "mean": [0.485, 0.456, 0.406], # Match normalization mean "std": [0.229, 0.224, 0.225] # Match normalization std }, "output": { "shape": [1, 2] # Output shape for your model (2 classes) } } } # Setting up the metadata with correct 'preview' params mlmodel.user_defined_metadata['com.apple.coreml.model.preview.params'] = json.dumps(labels_json) # Save the model as .mlmodel mlmodel.save("LemonClassifierGemini.mlmodel") mlmodel = ct.convert( trace, inputs=[_input], minimum_deployment_target=ct.target.iOS14 # Optional, set deployment target ) # Set model type as 'imageClassifier' for the Preview tab** mlmodel.type = 'imageClassifier' # Correct structure for preview parameters** (assuming two classes: 'lemon' and 'lime') labels_json = { "imageClassifier": { "labels": ["lemon", "lime"], "input": { "shape": list(input_tensor.shape), # Provide the actual input shape "mean": [0.485, 0.456, 0.406], # Match normalization mean "std": [0.229, 0.224, 0.225] # Match normalization std }, "output": { "shape": [1, 2] # Output shape for your model (2 classes) } } } # Setting up the metadata with correct 'preview' params** mlmodel.user_defined_metadata['com.apple.coreml.model.preview.params'] = json.dumps(labels_json) # Save the model as .mlmodel mlmodel.save("LemonClassifierGemini.mlmodel") My model is : Input batch shape: torch.Size([32, 3, 192, 192]) Labels batch shape: torch.Size([32]) Validation Loss: None, Validation Metric: None Predictions shape: torch.Size([63, 2]) Targets shape: torch.Size([63]) Code for the model : searches = 'lemon','lime' path = Path('lemon_or_not') for o in searches: dest = (path/o) dest.mkdir(exist_ok=True, parents=True) download_images(dest, urls=search_images(f'{o} photo')) time.sleep(5) resize_images(path/o, max_size=400, dest=path/o) dls = DataBlock( blocks=(ImageBlock, CategoryBlock), get_items=get_image_files, splitter=RandomSplitter(valid_pct=0.2, seed=42), get_y=parent_label, item_tfms=[Resize(192, method='squish')] ).dataloaders(path, bs=32) dls.show_batch(max_n=6) learn = vision_learner(dls, resnet18, metrics=error_rate) learn.fine_tune(3) is_lemon,_,probs = learn.predict(PILImage.create('lemon.jpg')) print(f"This is a: {is_lemon}.") print(f"Probability it's a lemon: {probs[0]:.4f}") This is a: lemon.

I used the multifunction models feature introduced in iOS 18 to merge three VAE Encoder models with different resolutions into a single model. However, loading this merged model on iOS causes a crash with the error EXC_BAD_ACCESS (code=1, address=0x0). In contrast, merging VAE Decoder models using the same method does not result in crashes. Additionally, merging only two VAE Decoder models with different resolutions also leads to a crash when loaded on iOS. As for the Stable Diffusion Unet model, merging two or even three models does not cause any crashes, and it successfully generates images as expected. I use the following code to load the model: let config = MLModelConfiguration() config.computeUnits = .cpuAndNeuralEngine config.functionName = "test" try MLModel(contentsOf: url, configuration: config)

When using the imagePlaygroundSheet modifier in SwiftUI, the system presets an image playground in a fixed size. Especially on macOS, this modal is rather small and doesn't utilize the available space efficiently. Is there a way to make the modal bigger, or allow the user to resize the dialog? I tried presentationDetents, but this would need to be applied to the content of the sheet, which is provided by the system... I guess this question applies to other system-provided sheets like the photo picker as well.

I am using the depthAnything v2 provided by Apple on the developer website. On my iPhone 15 Pro, if I choose all or cpuAndNeuralEngine, it will stuck in loading models. let config = MLModelConfiguration() config.computeUnits = .cpuAndGPU//normal when not using neuralEngine. let model = try await DepthModel.load(configuration: config) with following error: E5RT encountered an STL exception. msg = MILCompilerForANE error: failed to compile ANE model using ANEF.

Hi everyone, I'm working on an iOS app that uses VisionKit and I'm exploring the .visualLookUp feature. Specifically, I want to extract the detailed information that Visual Look Up provides after identifying an object in an image (e.g., if the object is a flower, retrieve its name; if it’s a clothing tag, get the tag's content).

I'm working on a cross-platform AI app. It is a CMake project. The inference part should be built as a library separately on Windows and MacOS. On MacOS it should be built with objective-c and CoreML. Here's my step roughly: Create a XCode Project for CoreML inference and build it as static library. Models are compiled to ".mlmodelc", and codes are compile to binary ".a" lib. Create a CMake Project for the app, and use the ".a" lib built by XCode. Run the App. I initialize the CoreML model like this(just for demostration): #include "det.h" // the model header generated by xcode auto url = [[NSURL alloc] initFileURLWithPath:[NSString stringWithFormat:@"%@/%@", dir, @"det.mlmodelc"]]; auto model = [[det alloc] initWithContentsOfURL:url error:&error]; // no error The url is valid, and the initialization doesn't report any error. However, when I tried to do inference using codes like this: auto cvPixelBuffer = createCVPixelBuffer(960, 960); // util function auto preds = [model predictionFromImage:cvPixelBuffer error:NULL]; The output preds will be null and I got these errors: 2024-12-10 14:52:37.678201+0800 望言OCR[50204:5615023] [e5rt] E5RT encountered unknown exception. 2024-12-10 14:52:37.678237+0800 望言OCR[50204:5615023] [coreml] E5RT: E5RT encountered an unknown exception.
