Hi i am trying to set up tensorflow-metal as instructed by https://developer.apple.com/metal/tensorflow-plugin/ when running line (python -m pip install tensorflow-metal) I get the following error: ERROR: Could not find a version that satisfies the requirement tensorflow-metal (from versions: none) ERROR: No matching distribution found for tensorflow-metal According to the troubleshooting section: "Check that the Python version used in the environment is supported (Python 3.8, Python 3.9, Python 3.10)." My current version is Python 3.9.12. Any insight would be great!

I'm working with MLSoundClassifier to try to look for 2 different sounds in a live audio stream. I have been debating with the team if it is better to train 2 separate models, one for each different sound, or train 1 model on both sounds? Has anyone had any experience with this. Some of us believe that we have received better results with the separate models and some with 1 single model trained on both sounds. Thank you!

I've only been using this late 2021 MBP 16 for nearly 2 years, and now the speaker is producing a crackling sound. Upon inquiring about repairs, customer service informed me that it would cost $728 to replace the speaker, which is a third of the price of the laptop itself. It's absolutely absurd that a $2200 laptop's speaker would fail within such a short period without any external damage. The repair cost being a third of the laptop's price is outrageous. I intend to initiate a petition in the US, hoping to connect with others experiencing the same problem. This is indicative of a subpar product, and customers shouldn't bear the burden of Apple's shortcomings. I plan to share my grievances on various social media platforms and if the issue persists, I will escalate it to the media for further exposure.

I'm exploring my Vision Pro and finding it unclear whether I can even achieve things like body pose detection etc. https://developer.apple.com/videos/play/wwdc2023/111241/ It's clear that I can apply it to self provided images, but how about to the data coming from visionOS SDKs? All I can find is this mesh data from ARKit, https://developer.apple.com/documentation/arkit/arkit_in_visionos - am I missing something or do we not yet have good APIs for this? Appreciate any guidance! Thanks.

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.

After migrating my ionic cordova app to ionic capacitor I am encountering a persistent white screen on a particular page. Along with this, I have observed the following error messages in the console: Error Message: [com.apple.VisionKit.RemoveBackground] Request to remove background on an unsupported device. Error Domain=com.apple.VisionKit.RemoveBackground Code=-8 "(null)" Error Message: [UILog] Called -[UIContextMenuInteraction updateVisibleMenuWithBlock:] while no context menu is visible. This won't do anything. The actual page becomes visible after clicking on that white screen. the same code is working fine for android build but facing issue on ios.

I'm using DataScannerViewController with SwiftUI to scan text and barcodes from a card. I would like the user to be able to hold the card in front of the device, but I am not finding a way to select the front camera with DataScannerViewController. Does anyone know of a way to select the front camera?

I haven't used the GPU implementation for over a year now due to constant issues (I use tf.config.set_visible_devices([], 'GPU') to use CPU only. I have also had a couple of issues with model convergence using GPU, however this issue seems more prominent, and possibly unrelated. Here is an example of code that causes a memory leak using GPU (I cannot link the dataset, but it is called: Text classification documentation, by TANISHQ DUBLISH on Kaggle. import pandas as pd import numpy as np import matplotlib.pyplot as plt import tensorflow as tf df = pd.read_csv('df_file.csv') df.head() train_df = df.sample(frac=0.7, random_state=42) val_df = df.drop(train_df.index).sample(frac=0.5, random_state=42) test_df = df.drop(train_df.index).drop(val_df.index) train_dataset = tf.data.Dataset.from_tensor_slices((train_df['Text'].values, train_df['Label'].values)).batch(32).prefetch(tf.data.AUTOTUNE) val_dataset = tf.data.Dataset.from_tensor_slices((val_df['Text'].values, val_df['Label'].values)).batch(32).prefetch(tf.data.AUTOTUNE) test_dataset = tf.data.Dataset.from_tensor_slices((test_df['Text'].values, test_df['Label'].values)).batch(32).prefetch(tf.data.AUTOTUNE) text_vectorizer = tf.keras.layers.TextVectorization(max_tokens=100_000, output_mode='int', output_sequence_length=1000, pad_to_max_tokens=True) text_vectorizer.adapt(train_df['Text'].values) embedding = tf.keras.layers.Embedding(input_dim=len(text_vectorizer.get_vocabulary()), output_dim=128, input_length=1000) inputs = tf.keras.layers.Input(shape=[], dtype=tf.string) x = text_vectorizer(inputs) x = embedding(x) x = tf.keras.layers.LSTM(64)(x) outputs = tf.keras.layers.Dense(5, activation='softmax')(x) model_2 = tf.keras.Model(inputs, outputs, name='model_2_lstm') model_2.compile(loss=tf.keras.losses.SparseCategoricalCrossentropy(), optimizer=tf.keras.optimizers.legacy.Adam(), metrics=['accuracy']) model_2_history = model_2.fit(train_dataset, epochs=50, validation_data=val_dataset, callbacks=[ tf.keras.callbacks.EarlyStopping(monitor='val_loss', patience=3, restore_best_weights=True), tf.keras.callbacks.ModelCheckpoint(model_2.name, save_best_only=True), tf.keras.callbacks.ReduceLROnPlateau(monitor='val_loss', patience=5, verbose=1) ])

I am currently facing a performance issue while using CoreML on iOS 16+ devices to run a simple grid_sample model. When profiling the model using xcode Profiler, I noticed that before each NPU computation, there is a significant delay caused by the "input copy" and "neural engine-data copy" operations.I have specified that both the input and output of the model are of type float16, there shouldn't be any data type convert. I would appreciate any insights or suggestions regarding the reasons behind this delay and possible solutions My simple model is class GridSample(torch.nn.Module): def __init__( self, ): super().__init__() def forward(self, input: torch.Tensor, grid: torch.Tensor) -> torch.Tensor: output = F.grid_sample( input, grid.to(input), mode='nearest', padding_mode='zeros', align_corners=True, ) return output tr_input = torch.randn((8, 64, 512, 512) tr_grid = torch.randn((8, 256, 256, 2) simple_model = GridSample() simple_model.eval() traced_model = torch.jit.trace(simple_model, [tr_input, tr_grid]) coreml_input = [coremltools.TensorType(name="image_input", shape=tr_input.shape, dtype=np.float16), coremltools.TensorType(name="warp_grid", shape=tr_grid.shape, dtype=np.float16)] mlmodel = coremltools.converters.convert(traced_model, inputs=coreml_input, convert_to="mlprogram", minimum_deployment_target=coremltools.target.iOS16, compute_units=coremltools.ComputeUnit.ALL, compute_precision = coremltools.precision.FLOAT16, outputs=[ct.TensorType(name="x0", dtype=np.float16)], debug=False) mlmodel.save("./grid_sample.mlpackage") os.system(f"xcrun coremlcompiler compile './grid_sample.mlpackage' './')

Hello, My understanding of the paper below is that iOS ships with a MobileNetv3-based ML model backbone, which then uses different heads for specific tasks in iOS. I understand that this backbone is accessible for various uses through the Vision framework, but I was wondering if it is also accessible for on-device fine-tuning for other purposes. Just as an example, if I want to have a model to detect some unique object in a photo, can I use the built in backbone or do I have to include my own in the app. Thanks very much for any advice and apologies if I didn't understand something correctly.

On an Apple M1 with Ventura 13.6. I followed the steps on the Get started with tensorflow-metal page here: https://developer.apple.com/metal/tensorflow-plugin/ python3 -m venv ~/venv-metal source ~/venv-metal/bin/activate python -m pip install -U pip python -m pip install tensorflow python -m pip install tensorflow-metal With a clean start I also tried a pinning python -m pip install tensorflow==2.13.0 Where Successfully installed tensorflow-metal-1.0.0 The table here suggested this should work. https://pypi.org/project/tensorflow-metal/ But I got the same error... Running Python code without the tensorflow import was not a problem. I found forums with similar error on Mac 1 but none of the proposed solution worked. Is there suggested steps to get the `get started tutorial working?

Is there a way to extract the list of words recognized by the Speech framework? I'm trying to filter out words that won't appear in the transcription output, but to do that I'll need a list of words that can appear. SFSpeechLanguageModel.Configuration can be initialized with a vocabulary, but there doesn't seem to be a way to read it, and while there are ways to create custom vocabularies, I have yet to find a way to retrieve it. I added the Natural Language tag in case the framework might contribute to a solution

After training my dataset, the training, validation, and testing sets all show 0% in detection accuracy and all my test photos show false negative. The dataset has 1032 photos and 2 classes, and I used Roboflow for the image annotation. For network, I choose full network. If there is any way to fix this?

Kia ora, Been having heaps of trouble recently trying to get TensorFlow working, it just suddenly stopped and the kernel would just crash every time I try to import tf. I've tried just about everything eg. fresh install of python, reinstalling Xcode dev tools Below is the relevant lines of pip freeze, using python 1.10.13 btw tensorboard==2.15.1 tensorboard-data-server==0.7.2 tensorboard-plugin-wit==1.8.1 tensorflow==2.15.0 tensorflow-estimator==2.15.0 tensorflow-io-gcs-filesystem==0.34.0 tensorflow-macos==2.15.0 tensorflow-metal==0.5.0 Below is the cell in question that is killing the kernal import tensorflow as tf import matplotlib.pyplot as plt import tensorflow_datasets as tfds from tensorflow.keras.layers import Conv2D, MaxPool2D, Dense, Flatten, InputLayer, BatchNormalization, Dropout from tensorflow.keras.losses import BinaryCrossentropy from tensorflow.keras.optimizers.legacy import Adam I'll be around all day so if you have anything that can help, I'll be sure to give it a go as soon as you post it and get back to you! Looking forward to your replies. Nga mihi, Kane

Hello! I'm implementing cropping an object from an image mechanism. @MainActor static func detectObjectOnImage(image: UIImage) async throws -> UIImage { let analyser = ImageAnalyzer() let interaction = ImageAnalysisInteraction() let configuration = ImageAnalyzer.Configuration([.visualLookUp]) let analysis = try await analyser.analyze(image, configuration: configuration) interaction.analysis = analysis return try await interaction.image(for: interaction.subjects) } My app supports iOS 16 and a compiler doesn't complain about the code.However when I run it on simulator with iOS 16, I'm getting "symbol not found" error on the app launch. Does anybody know what can be the issue?

WWDC22 video "Explore the machine learning development experience" provides Python code for an interesting application (real-time ML image colorization), but doesn't provide the complete Xcode project, and assumes viewer knows how to do Python in Xcode (haven't heard of such in 10 years of iOS development!). Any pointers to either the video's example Xcode project, or how to create a suitable Xcode project capable of running Python code?

I did a clean install of Python (v. 3.10), then Tensorflow & Tensorflow-Metal following exactly the process stated in Apple's plugin support page. Now, every time I run ANY python code with Tensorflow it crashes in the model.fit instruction. It does not matter what I feed into it, even code that used to run perfectly on my previous MacBook (Intel)... I've researched ad-vomitum for answers but Apple washes it's hands stating that is Tensorflow and Tensorflow does the same. Fact is that exactly the same code runs flawlessly on my Windows NVIDIA PC setup. I purchased the m3 laptop with the hope of having the possibility to train my neural networks "on the go"... now I lost $5,000 usd, I can't make it work, and is a total disaster. I am extremely competent in Python development and have been developing neural networks for years. So if you are going to comment, please avoid suggestions like "check your Python version" etc. - This is DEFINITIVELY due to the m3 Mac. Exact same setup is working OK on an M1-Ultra Mac Studio. It is just not portable... Does anyone have any specific advice on how to make a proper setup of Tensorflow for the Mac M3??
