Launcher Error

[XinDongol]

Got a lunch error

Try to lunch with specific logdir, even I use '/home', still return Directory not found.

If you need further details to debug, please comment.

Thanks a lot.

Hi @XinDongol, Sorry for reply late. this error may be caused by not installing jupyter_tensorboard.
If you have already installed jupyter_tensorboard and this issue still exists. please show me your jupyterlab error log.

Hi! @chaoleili
I resolved error that message invalid response: 404 by install jupyter_tensorboard. But, I can't understand error showed Cannot create tensorboard, Directory not found. This error be resolved by set my_log_dir_path first and default_log_dir_path one more time:(

[vBLFTePebWNi6c]

@keicoon After some workarounds I found that path to tensorboard logdir should be relative to the jupyterlab's root directory.
@chaoleili It would be nice if you'll write about it explicitly in README.md or somehow make path to tensorboard logdir absolute.

@vBLFTePebWNi6c Thanks for your advise! I have updated README.md

Sorry, I have already installed jupyter_tensorboard but still got Launcher error.
The log message is
"[W 16:40:27.510 LabApp] 404 GET /api/tensorboard?1546620027748 (10.1.1.121) 29.83ms"

Can you help me?
Thank you!

@dasing sorry for replying late, please check tensorflow >= 1.3 is installed. more info https://github.com/lspvic/jupyter_tensorboard#installation

[joequant]

Already installed jupyter_tensorboard

Can you let me know what log files I should look at?

[chesterli29]

What's your tensorboard version? if the tensorboard version >= 1.12 please ensure jupyter_tensorboard is update to 0.1.9.

[joequant]

Im using the nightly version of tensorflow. 在 2019年2月4日週一 下午1:05，Chester Li <notifications@github.com 寫道：

Got it to work. I think there was just a nightly glitch.

I still have this problem:

pip list | grep tensor
jupyter-tensorboard               0.1.9                 
tensorboard                       1.13.0

tensorflow-gpu                    1.13.1             

But I get when I open jupyterlab, in the browser

and the Jupyter log

[W 15:53:11.983 LabApp] 404 GET /api/tensorboard?1556034791980 (127.0.0.1) 1.06ms referer=http://localhost:8889/lab?

and when I click Tensorboard Button:

Any news on this?
I'm encountering the 404 error

This happens on my local machine, with JupyterLab & Jupyter_tensorboard installed as written in README

[letusfly85]

I also have similar troubles, and I fixed by seeing the following issue.

lspvic/jupyter_tensorboard#47

[shimk52]

Running:
jupyter tensorboard enable --user

worked for me
