I have converted an UIImage to MLShapedArray and by default this is NCHW format. I need to permute it into NCWH to prepare it for an ML model. What is the recommended way to achieve this ?

I'm building up a data frame for the sole purpose of using that lovely textual grid output. I'm getting output without any issue, but I'm trying to sort out how I might apply a formatter to a specific column so that print(dataframeInstance) "just works" nicely. In my use case, I'm running a function, collecting its output - appending that into a frame, and then using TabularData to get a nice output in a unit test, so I can see the patterns within the output. I found https://developer.apple.com/documentation/tabulardata/column/description(options:), but wasn't able to find any way to "pre-bind" that to a dataframe Column when I was creating it. (I have some double values that get a bit "excessive" in length due to the joys of floating point rounding) Is there a way of setting a formatter on a column at creation time, or after (using a property) that could basically use the same pattern as that description method above?

There are so many issues with tensorflow-metal: ADAM is slow Inconsistent values with CPU And now this, I saw a post regarding this but that was one year old. So, Macbooks are not even good for learning anymore?

When the input dimension is 600w, the operator runs on ANE. But when the input shape is 100w or 200w, this operator can only run on the CPU. The data dimension has decreased, but it does not run on ANE. What is the reason for this and what are the ways to avoid it

As the title suggests I am using AVAudioEngine for SpeechRecognition input & AVAudioPlayer for sound output. Apple says in this talk https://developer.apple.com/videos/play/wwdc2019/510 that the setVoiceProcessingEnabled function very usefully cancels the output from speaker to the mic. I set voiceProcessing on the Input and output nodes. It seems to work however the volume is low, even when the system volume is turned up. Any solution to this would be much appreciated.

What is the accuracy and resolution of the angles measured using Vision?

I am trying to parse text from an image, split it into words and store the words in a String array. Additionally I want to store the bounding box of each recognized word. My code works but for some reason the bounding boxes of words that are not separated by a space but by an apostrophe come out wrong. Here is the complete code of my VNRecognizeTextRequestHander: let request = VNRecognizeTextRequest { request, error in guard let observations = request.results as? [VNRecognizedTextObservation] else { return } // split recognized text into words and store each word with corresponding observation let wordObservations = observations.flatMap { observation in observation.topCandidates(1).first?.string.unicodeScalars .split(whereSeparator: { CharacterSet.letters.inverted.contains($0) }) .map { (observation, $0) } ?? [] } // store recognized words as strings recognizedWords = wordObservations.map { (observation, word) in String(word) } // calculate bounding box for each word recognizedWordRects = wordObservations.map { (observation, word) in guard let candidate = observation.topCandidates(1).first else { return .zero } let stringRange = word.startIndex..<word.endIndex guard let rect = try? candidate.boundingBox(for: stringRange)?.boundingBox else { return .zero } let bottomLeftOriginRect = VNImageRectForNormalizedRect(rect, Int(captureRect.width), Int(captureRect.height)) // adjust coordinate system to start in top left corner let topLeftOriginRect = CGRect(origin: CGPoint(x: bottomLeftOriginRect.minX, y: captureRect.height - bottomLeftOriginRect.height - bottomLeftOriginRect.minY), size: bottomLeftOriginRect.size) print("BoundingBox for word '\(String(word))': \(topLeftOriginRect)") return topLeftOriginRect } } And here's an example for what's happening. When I'm processing the following image: the code above produces the following output: BoundingBox for word 'In': (23.00069557577264, 5.718113962610181, 45.89460636656961, 32.78087073878238) BoundingBox for word 'un': (71.19064286904202, 6.289275587192936, 189.16024359557852, 34.392966621800475) BoundingBox for word 'intervista': (71.19064286904202, 6.289275587192936, 189.16024359557852, 34.392966621800475) BoundingBox for word 'del': (262.64622870703477, 8.558512219726875, 54.733978711037985, 32.79967358237818) Notice how the bounding boxes of the words 'un' and 'intervista' are exactly the same. This happens consistently for words that are separated by an apostrophe. Why is that? Thank you for any help Elias

I'm following Apple WWDC video (https://developer.apple.com/videos/play/wwdc2021/10037/) about how to create a recommendation model. But I'm getting this error when I run the project on that like of code from their tutorial. "Column keywords has element of unsupported type Dictionary<String, Double>." Here is the block of code took from the transcript of WWDC video that cause me issue: func featuresFromMealAndKeywords(meal: String, keywords: [String]) -> [String: Double] { // Capture interactions between content (the dish keywords) and context (meal) by // adding a copy of each keyword modified to include the meal. let featureNames = keywords + keywords.map { meal + ":" + $0 } // For each keyword, create an entry in a dictionary of features with a value of 1.0. return featureNames.reduce(into: [:]) { features, name in features[name] = 1.0 } } var trainingKeywords: [[String: Double]] = [] var trainingTargets: [Double] = [] for item in userPurchasedItems { // Add in the positive example. trainingKeywords.append( featuresFromMealAndKeywords(meal: item.meal, keywords: item.keywords)) trainingTargets.append(1.0) // Add in the negative example. let negativeKeywords = allKeywords.subtracting(item.keywords) trainingKeywords.append( featuresFromMealAndKeywords(meal: item.meal, keywords: Array(negativeKeywords))) trainingTargets.append(-1.0) } // Create the training data. var trainingData = DataFrame() trainingData.append(column: Column(name: "keywords" contents: trainingKeywords)) trainingData.append(column: Column(name: "target", contents: trainingTargets)) // Create the model. let model = try MLLinearRegressor(trainingData: trainingData, targetColumn: "target") Did DataFrame implementation changed since then and doesn't support Dictionary anymore? I'm at lost right now on how to reproduce their example.

Hi, I think many of us would love to be able to use our GPUs for Jax on the new Apple Silicon devices, but currently, the Jax-metal plugin is, for all effects and purposes, broken. Is it still under active development? Is there a planned release for a new version? thanks!

I seem to be having some trouble running the example app from the WWDC 2023 session on 3D Body Pose Detection (this one). I'm getting an issue about the request revision being incompatible, I tried searching the API documentation for any configuration that has been changed or introduced but to no avail. I also couldn't find much online for it. Is this a known issue? Or am I doing something wrong? Error in question: Unable to perform the request: Error Domain=com.apple.Vision Code=16 "VNDetectHumanBodyPose3DRequest does not support VNDetectHumanBodyPose3DRequestRevision1" UserInfo={NSLocalizedDescription=VNDetectHumanBodyPose3DRequest does not support VNDetectHumanBodyPose3DRequestRevision1}.

Hi, I have been trying to connect my microphone on my reason studio for days now without any outcome. So I was asked to download ASIO Driver on my mac. I realised that I have an IAC driver. I need help on downloading the Asio driver and wish to know if there will be a problem running it with the IAC driver. I also just upgraded without knowing from ventura to sonoma. Am using an audio iinterface(Focusrite scarlett solo to connect to the reason application and my mic is nt1-a rode but I can get a sound but cannot record. Will be overwhelmed if I can get help from here. Thanks

Currently in South Korea, due to my personal experiences with what seems like warranty but isn't, and the operation of a ruthless Genius Bar, I feel compelled to purchase the officially released Vision Pro. I'd like to discuss with other developers here about their thoughts on the release schedule. The product launched in the USA in February, but I'm curious about the months following for the secondary and tertiary launch countries. Naturally, we'll know the launch is imminent when local staff are summoned to the headquarters for training. However, the urgency for localized services, development, and personal purchase is growing on my mind.

Hi Apple Team, We have a technical query regarding one feature- Audio Recognition and Live captioning. We are developing an app for deaf community to avoid communication barriers. We want to know if there is any possibility to recognize the sound from other applications in an iPhone and show live captions in our application (based on iOS).

I created a word tagging model in CreateML and am trying to make predictions with it using the following code: let text = "$30.00 7/1/2023" let model = TaggingModel() let input = TaggingModelInput(text: text) guard let output = try? model.prediction(input: input) else { fatalError("Unexpected runtime error.") } However, the output separates "$" and "30.00" as separate tokens as well as "7", "/", "1", "/", etc. Is there any way to make sure prices and dates get grouped together and to simply separate tokens based on whitespace? Any help is appreciated!

I am sending CVPixelBuffers to the input of the DeepLabV3 MLModel. I am of the understanding that it requires pixel color format 32ARGB or 32RGBA. Correct? Can 32BRGA be input? CVPixelBuffers support 32BRGA and OpenCV as well. Please note, I want to use the MLModel as trained. Neither 32RGBA no 32ARGB are supported for type CVPixelBuffer. 32ARGB: An unsupported runtime error occurs with the configuration as follows... func configureOutput() { videoOutput.setSampleBufferDelegate(self, queue: bufferQueue) videoOutput.alwaysDiscardsLateVideoFrames = true videoOutput.videoSettings = [String(kCVPixelBufferPixelFormatTypeKey): kCMPixelFormat_32ARGB]. 32RGBA: "Cannot find 'kCMPixelFormat_32rgba' in scope." The app process: Video captured pixelBuffers are sent to c++ code where openCV operations are done, creating up to 3 smaller Mats which are then converted back into pixel buffers in the Objective-C. These converted PixedBuffer are used in three ways. All are sent to the MLModel for image segmentation to identify people; the files may be sent to the photo library; or may simply be viewed on the screen. I need a color format that can support all these down stream operations/pipelines.
