How can I run Tensorboard on a remote server?

问题

I'm new to Tensorflow and would greatly benefit from some visualizations of what I'm doing. I understand that Tensorboard is a useful visualization tool, but how do I run it on my remote Ubuntu machine?

回答1:

Here is what I do to avoid the issues of making the remote server accept your local external IP:

when I ssh into the machine, I use the option -L to transfer the port 6006 of the remote server into the port 16006 of my machine (for instance): ssh -L 16006:127.0.0.1:6006 olivier@my_server_ip

What it does is that everything on the port 6006 of the server (in 127.0.0.1:6006) will be forwarded to my machine on the port 16006.

You can then launch tensorboard on the remote machine using a standard tensorboard --logdir log with the default 6006port
On your local machine, go to http://127.0.0.1:16006 and enjoy your remote TensorBoard.

You can port-forward with another ssh command that need not be tied to how you are connecting to the server (as an alternative to the other answer). Thus, the ordering of the below steps is arbitrary.

from your local machine, run

ssh -N -f -L localhost:16006:localhost:6006 <user@remote>
on the remote machine, run:

tensorboard --logdir <path> --port 6006
Then, navigate to (in this example) http://localhost:16006 on your local machine.

(explanation of ssh command:

-N : no remote commands

-f : put ssh in the background

-L <machine1>:<portA>:<machine2>:<portB> :

forward <machine2>:<portB> (remote scope) to <machine1>:<portA> (local scope)

You don't need to do anything fancy. Just run:

tensorboard --host 0.0.0.0 <other args here>

and connect with your server url and port. The --host 0.0.0.0 tells tensorflow to listen from connections on all IPv4 addresses on the local machine.

回答4:

Find your local external IP by googling "whats my ip" or entering this command: wget http://ipinfo.io/ip -qO -
Determine your remote external IP. This is probably what comes after your username when ssh-ing into the remote server. You can also wget http://ipinfo.io/ip -qO - again from there too.
Secure your remote server traffic to just accept your local external IP address
Run Tensorboard. Note the port it defaults to: 6006
Enter your remote external IP address into your browser, followed by the port: 123.123.12.32:6006

If your remote server is open to traffic from your local IP address, you should be able to see your remote Tensorboard.

Warning: if all internet traffic can access your system (if you haven't specified a single IP address that can access it), anyone may be able to view your TensorBoard results and runaway with creating SkyNet themselves.

Another option if you can't get it working for some reason is to simply mount a logdir directory on your filesystem with sshfs:

sshfs user@host:/home/user/project/summary_logs ~/summary_logs

and then run Tensorboard locally.

This is not a proper answer but a troubleshooter, hopefully helps other less seasoned networkers like me.

In my case (firefox+ubuntu16) the browser was connecting, but showing a blank page (with the tensorboard logo on the tab), and no log activity at all was shown. I still don't know what could be the reason for that (didn't look much into it but if anybody knows please let know!), but I solved it switching to ubuntu's default browser. Here the exact steps, pretty much the same as in @Olivier Moindrot's answer:

On the server, start tensorboard: tensorboard --logdir=. --host=localhost --port=6006
On the client, open the ssh tunnel ssh -p 23 <USER>@<SERVER> -N -f -L localhost:16006:localhost:6006
Open ubuntu's Browser and visit localhost:16006. The tensorboard page should load without much delay.

To check that the SSH tunnel is effectively working, a simple echo server like this python script can help:

Put the script into an <ECHO>.py file in the server and run it with python <ECHO>.py. Now the server will have the echo script listening on 0.0.0.0:5555.
On the client, open the ssh tunnel ssh -p <SSH_PORT> <USER>@<SERVER> -N -f -L localhost:12345:localhost:5555
On the client, in the same terminal used to open the tunnel (step 2.), issuing telnet localhost 12345 will connect to the echo script running in the server. Typing hello and pressing enter should print hello back. If that is the case, your SSH tunnel is working. This was my case, and lead me to the conclusion that the problem involved the browser. Trying to connect from a different terminal caused the terminal to freeze.

As I said, hope it helps!
Cheers,
Andres

You have to create a ssh connection using port forwarding:

ssh -L 16006:127.0.0.1:6006 user@host

Then you run the tensorboard command:

tensorboard --logdir=/path/to/logs

Then you can easily access the tensorboard in your browser under:

localhost:16006/

回答8:

You can directly run the following command on terminal of your remote server to run tensorboard:

tensorboard --logdir {tf_log directory path} --host "0.0.0.0" --port 6006

Or you can also start the tensorboard within your ipython notebook:

%load_ext tensorboard
%tensorboard --logdir {tf_log directory path} --host "0.0.0.0" --port 6006

回答9:

While running the tensorboard give one more option --host=ip of your system and then you can access it from other system using http://ip of your host system:6006
