Description

I am using multiple tensoboard callbacks with the same Model. Since I upgraded Tensorflow from 2.5 to 2.8, I have an error at the end of the training when closing the Tensorboard writers.

Research direction

Start with the linked TensorFlow issue and reproduce the failure using multiple TensorBoard callbacks on the same model under TensorFlow 2.8, comparing with 2.5 if available. The work is done when the callbacks close their writers without the reported end-of-training error and the behavior is covered by an appropriate regression test.
