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?

"whats my ip"
or entering this command: wget http://ipinfo.io/ip -qO -
wget http://ipinfo.io/ip -qO -
again from there too.6006
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.
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/
Here is what I do to avoid the issues of making the remote server accept your local external IP:
-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
.
tensorboard --logdir log
with the default 6006
portWhile 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
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.
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 <machine1>:<portA>
(local scope) to <machine2>:<portB>
(remote scope)
Another approach is to use a reverse proxy, which allows you to view Tensorboard from any internet connected device without SSHing. This approach can make it far easier / tractable to view Tensorboard on mobile devices, for example.
Steps:
1) Download reverse proxy Ngrok on your remote machine hosting Tensorboard. See https://ngrok.com/download for instructions (~5 minute setup).
2) Run ngrok http 6006
(assuming you're hosting Tensorboard on port 6006)
3) Save the URL that ngrok outputs:
4) Enter that into any browser to view TensorBoard:

For anyone who must use the ssh keys (for a corporate server).
Just add -i /.ssh/id_rsa
at the end.
$ ssh -N -f -L localhost:8211:localhost:6007 myname@servername -i /.ssh/id_rsa
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:
tensorboard --logdir=. --host=localhost --port=6006
ssh -p 23 <USER>@<SERVER> -N -f -L localhost:16006:localhost:6006
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:
<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.ssh -p <SSH_PORT> <USER>@<SERVER> -N -f -L localhost:12345:localhost:5555
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,

--bind_all
option is useful.
$ tensorboard --logdir runs --bind_all
The port will be automatically selected from 6006 incrementally.(6006, 6007, 6008... )
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
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.
