AttributeError: 'TrackableWeightHandler' object has no attribute 'name'

Maybe the same issue
Here is the colab

When use both tensorboard and tf.keras.layers.experimental.preprocessing'layer , It raises error :

This issue doesn't seem to relate to TensorFlow profiler. I think you can file the issue to TensorBoard:
https://github.com/tensorflow/tensorboard/issues

@qiuminxu @DachuanZhao did you ever find out the cause of this issue?
