Access tensorboard with nbserverproxy?

[dbuscombe-usgs]

Is there any way to launch a web browser from within a notebook, to view localhost?

http://jupyter-dbuscombe-2dusgs:6006

It is for accessing tensorboard outputs

This should be possible with https://github.com/jupyterhub/nbserverproxy, which is used by the Dask dashboard to proxy port 8787 to urls like:
http://pangeo.esipfed.org/user/rsignell-usgs/proxy/8787/status

Thanks. I'm almost there

I can launch tensorboard with a bang command within a notebook cell:

!tensorboard --logdir=/tmp/tensorflow_logs

then it is starts to load at

http://pangeo.esipfed.org/user/dbuscombe-usgs/proxy/6006

(I see the orange "tensorboard" banner)

but it hangs indefinitely with the message "Loading active dashboards". Is there something intercepting or a simple explanation why it doesn't load the whole page?

This is what I see

@jjhelmus, we are two domain scientists(!) trying to get a jupyterhub instance ready for a class on machine learning with 40 students, and you popped up when I googled "tensorboard" and "nbserverproxy".

Do you know whether this problem is:

• a nbserverproxy issue
• a tensorboard/tensorflow/jupyterhub issue
• user error
• something else?

[jjhelmus]

I am not familiar enough with jupyterhub nor nbserverproxy to provide any help with this issue.

@jjhelmus, thanks for looking. It was worth a shot!

@dbuscombe-usgs , is it possible to call tensorboard in the notebook instead of from the command line?

Would either of the solutions here work?

Thanks but I can't get any of these options to work.

Appreciate this is an old issue but may be resolved with the new absolute URL proxy.

<notebook-base>/proxy/absolute/<port>
