terminating with uncaught exception of type NSException

I install tensorflow metal following official guide. Everything is fine, even with tf.test.is_gpu_available.

But when I try to test tensorflow, here is my bug report:

libc++abi: terminating with uncaught exception of type NSException

Abort trap: 6

I am using MacBook Air (M1, 2020) with the latest OS.

My code is

import tensorflow as tf
import time

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, activation='softmax')
])

model.compile(optimizer='adam',
              loss='sparse_categorical_crossentropy',
              metrics=['accuracy'])


start = time.time()

model.fit(x_train, y_train, epochs=10)

end = time.time()

model.evaluate(x_test, y_test)
print("time consumed: ", end - start)

I do not think there is something wrong with my code.
