Tensorboard fails in python 3.13 because imghdr module is absent

[Bichidian]

Running tensorboard --logdir . under python 3.13 leads to the following error:

Traceback (most recent call last):
  File ".venv/bin/tensorboard", line 5, in <module>
    from tensorboard.main import run_main
  File ".venv/lib64/python3.13/site-packages/tensorboard/main.py", line 27, in <module>
    from tensorboard import default
  File ".venv/lib64/python3.13/site-packages/tensorboard/default.py", line 40, in <module>
    from tensorboard.plugins.image import images_plugin
  File ".venv/lib64/python3.13/site-packages/tensorboard/plugins/image/images_plugin.py", line 18, in <module>
    import imghdr
ModuleNotFoundError: No module named 'imghdr'

It seems that imghdr is no longer part of the Python standard library in 3.13.

Thanks for reporting. We'll look for a replacement for this library.

AFAICT, we only use it to get MIME types, which I expect should be somewhat easily replaceable, but we can't guarantee when we'll address this. In the meantime, Python < 3.13 would be required.

You can install standard-imghdr for temporary fix
