Enable Tensorboard on the hub

[jbusecke]

@SammyAgrawal this one is for you, since I remember you wanted to use tensorboard?

Take a look at the jupyter-server-proxy docs:
https://jupyter-server-proxy.readthedocs.io/en/latest/arbitrary-ports-hosts.html#with-jupyterhub

I think there might be a way to write a simple url so you can navigate to a local port on the hub. Let me know if that works.

It does the same as it does inline; tries to load tensorboard (tab title is correct) but the actual screen is blank. Will try troubleshooting to see if jupyterhub issue or (more likely) a pytorch one

I talked to Yuvi two days ago and he said the important thing is that you can change the base_url, which seems like it is the case for tensorboard!

If you can set the base_url to leap.2i2c.cloud/hub/user-redirect/proxy/ this might work (@yuvipanda did I get this right?)

Looking into wandb as an alternative

Does https://github.com/kopwei/jupyter-tensorboard-proxy help?

[jbusecke]

@SammyAgrawal do you have capacity to add jupyter-tensorboard-proxy to the pangeo-ml image following the new guide and testing this? Or can we install this on the fly @yuvipanda?

has to be in the image unfortunately
