When fitting a CNN model, every second Epoch takes zero seconds and with OUT_OF_RANGE warnings. Im using structured folders of categorical images for training and validation. Here is the warning message that occurs after every second Epoch.

Hi, I just noticed that using the jax.numpy.insert() function returns an incorrect result (zero-padding the array) when compiled with jax.jit. When not jitted, the results are correct Config: M1 Pro Macbook Pro 2021 python 3.12.3 ; jax-metal 0.0.6 ; jax 0.4.26 ; jaxlib 0.4.23 MWE: import jax import jax.numpy as jnp x = jnp.arange(20).reshape(5, 4) print(f"{x=}\n") def return_arr_with_ins(arr, ins): return jnp.insert(arr, 2, ins, axis=1) x2 = return_arr_with_ins(x, 99) print(f"{x2=}\n") return_arr_with_ins_jit = jax.jit(return_arr_with_ins) x3 = return_arr_with_ins_jit(x, 99) print(f"{x3=}\n") Output: x2 (computed with the non-jitted function) is correct; x3 just has zero-padding instead of a column of 99 x=Array([[ 0, 1, 2, 3], [ 4, 5, 6, 7], [ 8, 9, 10, 11], [12, 13, 14, 15], [16, 17, 18, 19]], dtype=int32) x2=Array([[ 0, 1, 99, 2, 3], [ 4, 5, 99, 6, 7], [ 8, 9, 99, 10, 11], [12, 13, 99, 14, 15], [16, 17, 99, 18, 19]], dtype=int32) x3=Array([[ 0, 1, 2, 3, 0], [ 4, 5, 6, 7, 0], [ 8, 9, 10, 11, 0], [12, 13, 14, 15, 0], [16, 17, 18, 19, 0]], dtype=int32) The same code run on a non-metal machine gives the correct results: x=Array([[ 0, 1, 2, 3], [ 4, 5, 6, 7], [ 8, 9, 10, 11], [12, 13, 14, 15], [16, 17, 18, 19]], dtype=int32) x2=Array([[ 0, 1, 99, 2, 3], [ 4, 5, 99, 6, 7], [ 8, 9, 99, 10, 11], [12, 13, 99, 14, 15], [16, 17, 99, 18, 19]], dtype=int32) x3=Array([[ 0, 1, 99, 2, 3], [ 4, 5, 99, 6, 7], [ 8, 9, 99, 10, 11], [12, 13, 99, 14, 15], [16, 17, 99, 18, 19]], dtype=int32) Not sure if this is the correct channel for bug reports, please feel free to let me know if there's a more appropriate place!

Hello iOS Developer Community, I hope this message finds you healthy and happy. I am reaching out to seek your expertise and assistance with a particular challenge I’ve encountered while using the Speak Screen and Speak Selection features on iOS. As you may know, these features are incredibly useful for reading text aloud, but they sometimes struggle with the correct pronunciation of homographs—words that are spelled the same but have different meanings and pronunciations. An example of this is the word “live,” which can be pronounced differently based on the context of the sentence. To enhance my user experience, I am looking to input corrections for the pronunciation of “live” in its “happening now” context, such as in “live broadcast” or “live event.” However, the current process requires manual entry for each phrase, which is quite labor-intensive. I am wondering if there is a way to automate or streamline this process, perhaps through a shortcut or script that allows for bulk input of these corrections. Additionally, if anyone has already compiled a list of common phrases with homographs and their correct pronunciations, I would greatly appreciate it if you could share it or guide me on where to find such resources. Your insights and guidance on this matter would be invaluable, and I believe any solutions could benefit not just myself but many other users facing similar issues. Thank you for your time and consideration. I look forward to any suggestions or advice you may have. Best regards, Alec

Will macos support amd rx7600?

Hello, We all face issues with the latest tensorflow gpu. Incorrect result, errors etc... We all agreed to pay extra for the M1/2/3 so we could work on a professional grade computer but in the end we must use CPU. When will apple actually comment on that and provide updates. I totally understand these issues aren't fixed overnight and take some time, but i've never seen any apple dev answer saying that they understand and they're working on a fix. I've basically bought a Mac M3 Pro to be able to run on GPU some stuff without having to purchase a server and it's now useless. It's really frustrating.

Hello! We have an app that utilises the SpeechKit Framework. Especially the local on-device speech recognition for the audio files with the user selected language. Up until recently it worked as expected. However after updating one of our testing device to iOS 17.4.1 we found out that the local recognition on it stopped working completely. The error that we are getting has code 102 at its localised description reads: "Failed to access assets". That sounds just like a rear though known issue in previous iOS versions. The solution was inconvenient for our users but at least it worked – they were to go to the System settings and tweak with the dictation setting in the keyboard section. Right now no tweaks of this sort appear to help us fix the situation. We even tried to do the setting reset of the device (not the factory reset though). The error persists. it appears one one of our devices 100% of the time, halting the local recognition process. It sometimes shows on other devices for some particular languages too, but it does not show for other languages. As it is a UX breaking bug for our app, today I decided to check the logs of the Console app at the moment of the recognition attempt. There are lots of errors with code 1101 which from our research appear to be the general notifications about some local recognition setup problems. Removing the lines about the 1101 error from the log we have some interesting stuff remaining, that is (almost) never mentioned in any of the searchable webpages in the Internet. I assume they are the private API calls that the SpeechKit Framework executes under the hood: default localspeechrecognition -[UAFAssetSet assetNamed:]_block_invoke 9067C4F1-0B29-4A57-85DD-F8740DF7C344: No assets in asset set com.apple.siri.understanding default localspeechrecognition -[UAFAssetSet assetNamed:] 9067C4F1-0B29-4A57-85DD-F8740DF7C344: Returning com.apple.siri.asr.assistant from source none error localspeechrecognition -[SFEntitledAssetManager _assetWithAssetConfig:regionId:] No asset found with name: com.apple.siri.asr.assistant, asset set: com.apple.siri.understanding, usage: <private> error localspeechrecognition +[LSRConnection modelRootWithLanguage:clientID:modelOverrideURL:returningAssetType:error:] Fetch asset error (null) error localspeechrecognition -[LSRConnection prepareRecognizerWithLanguage:recognitionOverrides:modelOverrideURL:anyConfiguration:task:clientID:error:] modelRoot is nil (null) default OurApp [0x113e96d40] invalidated because the current process cancelled the connection by calling xpc_connection_cancel() Looks like there are some language-model related problems that appeared after the device was updated to 17.4.1. The Settings -> General -> Keyboard -> Dictation Languages appear to be configured correctly, the dictation toggle is On, we tried tweaking all these setting, rebooting the device and resetting the device settings. However the log lines still tell us that there is something wrong with the private resources of the SpeechKit framework. We are very concerned as the speech recognition is the core of out application's logic. And we don't understand what is the scale of possible impact of such a faulty behaviour (rare occurrences / some users / all users?) and how we can fix it to provide our users with the desired behaviour.

Hardware: 16" 2023 MBP M3 Pro OS: 14.4.1 Memory: 36 GB python version: 3.8.16 TF-Metal version: tensorflow-metal 1.0.1 installed via pip TF version: 2.13.0 Tensorflow-Metal starts pretty slow, approximately 10s/iteration and over the course of 36 iteration progressively slows down to over 120s/iteration. Info log prints out that TFLite is using XNNPack. Can't share the TFLite model but it is relatively shallow, small, and simple. Uninstalled TF-Metal, and installed tensorflow. Inference speed picks right up and is rock solid at 0.78s/iteration. What is going on??? **TLDR, TFLite inference speed: TF Metal = 120s/iteration TF = 0.78s/iteration**

Hello! I'm writing to the Apple developers to request the addition of an API for downloading premium voices directly within the app. Currently, this can only be done via the settings, which is not convenient for our users. As a developer for an application where this plays a crucial role, I ask you to take this into consideration. Thank you!

I hope this message finds you well. I recently had the opportunity to watch the insightful session titled "Improve Core ML Integration with Async Prediction" and was thoroughly impressed by the depth of information and the practical demonstration provided. The session offered valuable insights that I believe would greatly benefit my ongoing projects and my understanding of Core ML integration. As I am keen on implementing the demonstrated workflows and techniques within my own work, I am reaching out to kindly request access to the source code and any related material presented during the session. Having access to the code would enable me to better understand the concepts discussed and apply them more effectively in real-world scenarios. I believe that being able to review and experiment with the actual code would significantly enhance my learning experience and the implementation efficiency of my projects. It would also serve as a valuable resource for referencing best practices in Core ML integration and async prediction techniques. Thank you very much for considering my request. I greatly appreciate the effort that went into creating such an informative session and am looking forward to potentially exploring the material in greater depth. Best regards, Fabio G.

The application is developed in SwiftUI. Our application is responsible for audio recording, transcribing the audio file and uploading it to the backend. So, the 2 main components on the iOS application are : AVAudioRecorder, SFSpeechRecognizer. The UI compromises a visual design which showcases the recording of audio, and lets the user know if the audio is being recorded on not using a Text component. Lately the customer has been complaining that though the application says “Recording ” on the UI, their audios are not being are not being received at the backend. The customers try restarting there device(iPad) and the application started working normally We haven’t been able to reproduce the issue. But we suspect an intermittent failure in audio transmission or a potential UI freezing. Note : I have tried using Leaks instrument and had not encountered any memory leaks while using the application. Is there a way to determine whether the issue lies with the audio recorder, the speech recognizer, or elsewhere in the app? Are there any known issues or limitations with audio recorder lately on iOS that could be causing this behaviour? Please let me know if you have any suggestions to diagnose this issue. Also, do let me know if more information is required Thank you in advance

I am using VNRecognizeTextRequest to read Chinese characters. It works fine with text written horizontally, but if even two characters are written vertically, then nothing is recognized. Does anyone know how to get the vision framework to either handle vertical text or recognize characters individually when working with Chinese? I am setting VNRequestTextRecognitionLevel to accurate, since setting it to fast does not recognize any Chinese characters at all. I would love to be able to use fast recognition and handle the characters individually, but it just doesn't seem to work with Chinese. And, when using accurate, if I take a picture of any amount of text, but it's arranged vertically, then nothing is recognized. I can take a picture of 1 character and it works, but if I add just 1 more character below it, then nothing is recognized. It's bizarre. I've tried setting usesLanguageCorrection = false and tried using VNRecognizeTextRequestRevision3, ...Revision2 and ...Revision1. Strangely enough, revision 2 seems to recognize some text if it's vertical, but the bounding boxes are off. Or, sometimes the recognized text will be wrong. I tried playing with DataScannerViewController and it's able to recognize characters in vertical text, but I can't figure out how to replicate it with VNRecognizeTextRequest. The problem with using DataScannerViewController is that it treats the whole text block as one item, and it uses the live camera buffer. As soon as I capture a photo, I still have to use VNRecognizeTextRequest. Below is a code snippet of how I'm using VNRecognizeTextRequest. There's not really much to it and there aren't many other parameters I can try out (plus I've already played around with them). I've also attached a sample image with text laid out vertically. func detectText( in sourceImage: CGImage, oriented orientation: CGImagePropertyOrientation ) async throws -> [VNRecognizedTextObservation] { return try await withCheckedThrowingContinuation { continuation in let request = VNRecognizeTextRequest { request, error in // ... continuation.resume(returning: observations) } request.recognitionLevel = .accurate request.recognitionLanguages = ["zh-Hant", "zh-Hans"] // doesn't seem have any impact // request.usesLanguageCorrection = false do { let requestHandler = VNImageRequestHandler( cgImage: sourceImage, orientation: orientation ) try requestHandler.perform([request]) } catch { continuation.resume(throwing: error) } } }

I tried running inference with the 2B model from https://github.com/google-deepmind/gemma on my M2 MacBook Pro, but it segfaults during sampling: https://pastebin.com/KECyz60T Note: out of the box it will try to load bfloat16 weights, which will fail. To avoid this, I patched line 30 in gemma/params.py to explicitly cast to float32: param_state = jax.tree_util.tree_map(lambda p: jnp.array(p, jnp.float32), params)

I would like to contact a developer on the SSML team regarding the possibility to create a new downloadable voice, in a language yet unsupported. I don't mind making a free contribution. Creating Custom voices does not seem to be a solution, since only English is supported when creating a custom voice.
