如何将adam优化器指标添加到tensorboard？

import tensorflow as tf
from tensorflow.keras.optimizers import Adam

log_dir = "logs/optimizer"
tensorboard_callback = tf.keras.callbacks.TensorBoard(log_dir=log_dir, histogram_freq=1)

model = tf.keras.Sequential(...)
model.compile(optimizer=Adam(), loss='...', metrics=['accuracy'])

model.fit(x_train, y_train, epochs=..., callbacks=[tensorboard_callback])

tensorboard --logdir logs/optimizer
