How to add tensorboard logging?

[Dmitry Tyugin]

I'm trying to add tensorboard logging to mask_rcnn.py train function

    log_dir = "logs/" + datetime.datetime.now().strftime("%Y%m%d-%H%M%S")
    tensorboard_callback = tf.keras.callbacks.TensorBoard(log_dir=log_dir, histogram_freq=1)

    callb = [
        tensorboard_callback,
        ModelCheckpoint(self.checkpoint_path,save_weights_only=True,save_best_only = True, monitor = "val_loss", verbose = 0), 
        lr_rate,
    ] 

But training failed with error on start. Do you have any suggestions how to fix it? (I have tensorboard and tensorflow 2.5.0)

A small workaround would be setting the Histogram Frequency to 0. However if you need the histogram I don't know a solution.
