The AdamOptimizer is still causing crashes with: tensorflow-metal 0.3.0 tensorflow-macos 2.7.0

This code crashes with the 'adam' optimzer. It does work with 'SGD'. I am running Monterey 12.1 beta, and the latest versions of tensorflow-macos and tensorflow-metal from pypi. import tensorflow as tf mnist = tf.keras.datasets.mnist (x_train, y_train), (x_test, y_test) = mnist.load_data() x_train, x_test = x_train / 255.0, x_test / 255.0 model = tf.keras.models.Sequential([ tf.keras.layers.Flatten(input_shape=(28, 28)), tf.keras.layers.Dense(128, activation='relu'), tf.keras.layers.Dropout(0.2), tf.keras.layers.Dense(10) ]) predictions = model(x_train[:1]).numpy() tf.nn.softmax(predictions).numpy() loss_fn = tf.keras.losses.SparseCategoricalCrossentropy(from_logits=True) loss_fn(y_train[:1], predictions).numpy() model.compile(optimizer = 'adam', loss = loss_fn) model.fit(x_train, y_train, epochs=100)

Hi, Your example runs for me on Monterey 12.0.1 with Python 3.8 ... if I replace the ADAM optimizer with SGD. model.compile( loss='sparse_categorical_crossentropy', optimizer=tf.keras.optimizers.SGD(0.001), metrics=['accuracy'], ) I've noticed ADAM crash the session.

I was able to profile keras/tensorflow example code with a tensorflow-metal virtual environment. Please note the profile tab will only display results in Google Chrome. In Safari the Profile tab was empty.

Fixed with tensorflow-metal version 0.1.2
