Keras - failure to create TensorBoard directory

I am trying to create multiple graphs in TensorBoard by saving in separate sub directories, similar to as described here.

However I seem to get an error on the callback - I'm not sure why it is erroring.

Callback:

tensorboard = TensorBoard(log_dir=f"./logs/MODEL", histogram_freq=1,
                                  write_grads=True)

Error:

I had the same problem. I changed the / to \ and it worked

This worked for me in Windows

log_dir="logs\\model\\"

Had this very same problem. The solution in my case was to wrap the path with Path (from pathlib module) object - it fixes and normalizes all path slashes problems (works both on Windows and Linux build agent), e.g. :

from pathlib import Path
training_log_dir_path = Path((os.path.join(getRootDir(), log_dir, 't-', mversion)))
training_log_dir = str(training_log_dir_path)
