Tensorboard: path /[[_dataImageSrc]] not found, sending 404

[AnneMaelle]

Hi,

I was trying to run TensorBoard example : mnist_with_summaries.py and when I tried to open an instance of TensorBoard I got this :
command:
tensorboard --logdir=/output --host localhost --port=6006

output:
TensorBoard 1.5.1 at http://localhost:6006 (Press CTRL+C to quit)
W0219 15:12:02.944875 Thread-1 application.py:273] path /[[_dataImageSrc]] not found, sending 404

When I try to open http://localhost:6006, my browser crash.

I am on Ubuntu 16.04, with tensorflow GPU and the 1.5.1 version

What browser were you using? Also, what exactly do you meant by crash - did the whole browser quit unexpectedly? Or just the page/tab crashed?

If you can try running tensorboard again with a non-existent log directory, like --logdir=/tmp/fakelogdir then can you see if it still crashes in that case or if it loads normally? If you're able to load the page and check your browser's javascript console (e.g. the Chrome developer tools javascript console) for any messages and post those here, that would also be useful in debugging.

I am using Mozilla Firefox, and the whole browser crash whenever I try to access localhost. Changing directory doesn't change anything.

The crash report mentions :

MozCrashReason: MOZ_CRASH(GFX: Unexpected GLSL version.)
Notes: Ubuntu 16.04.3 LTSFP(D00-L1000-W00000000-T000) OpenGL: NVIDIA Corporation -- GeForce GT 750M/PCIe/SSE2 -- 4.6.0 NVIDIA 390.30 -- texture_from_pixmap

I tried it on Chrome and it worked, thank you for your help !

[nfelt]

Hmm, yeah it looks like maybe a WebGL + Firefox issue - I found this bug that's possibly relevant: https://bugzilla.mozilla.org/show_bug.cgi?id=1382358

You might try updating either Firefox or your nvidia GPU drivers but that's about all I would be able to suggest.

Glad it's working in Chrome at least! If you're still seeing the 404 error for "path /[[_dataImageSrc]]" not found I'd maybe try updating to the very latest TensorBoard via

pip uninstall tensorflow-tensorboard
pip install tensorboard

That should put you on TensorBoard 1.6.0. If the 404 is still happening on that version, let us know and we'll investigate further.

I hit this today as well, but no crash and another file 404s on Firefox 59.0.2 on macOS. I see this in my console:

W0502 19:02:41.443535 Thread-1 application.py:272] path /[[_dataImageSrc]] not found, sending 404
W0502 19:02:41.477539 Thread-1 application.py:272] path /[[_imageURL]] not found, sending 404

And the associated 404s in the dev tools:

Everything is fine on Chrome and Safari. I'm using TensorBoard 1.7.0.

[nfelt]

One thing to try might be changing the relevant src attributes to bind using src$="[[_name]]" rather than src= - see this section for details: https://www.polymer-project.org/1.0/docs/devguide/data-binding#attribute-binding

I'm not sure if that would actually fix this; the page doesn't mention src as a native property that requires attribute binding. But since it is similar to href which is so mentioned, that might be worth trying.

Since it sounds like so far this just produces 404s on the console/log and doesn't actually impair function, we may not have time to look into this further for a while, but if somebody is motivated to fix this we'll happily take a PR.

Hi.

I got the same issue, having “W0219 15:12:02.944875 Thread-1 application.py:273] path /[[_dataImageSrc]] not found, sending 404” and the firefox tab crushed(showing white page, and got some script error).

But I realized that firedox update has been downloaded, and when I applied the update, error doesn’t occur anymore.

Hope this info helps.

to use the google browers fix my problem

[stephanwlee]

PR #1315 should fix the issue. Please reopen the issue if a next release does not address the issue. Thank you!

[ghost]

I also have the same problem even though Tensorboards is blaming my CPU ...

[stephanwlee]

Hi @miracode2033, it should be fixed in 1.10 or 1.11. You seem to be using 1.7.0

[ghost]

Thank you @stephanwlee Let me check it out.

[mammadjv]

@fishguysword Switched to chromium and solved my problem ;)
Thanks

Hi @stephanwlee, I'm using tensorboard 1.11 and still get the same error:

Also the graphs load extremely slowly. They begin buy loading only the train plots and takes 60' to load valid and test plots.

[stephanwlee]

@kirk86 I believe those have been addressed in #1505 and is part of 1.12 release. Please try to upgrade :)

[kirk86]

@stephanwlee upgrade to which version? I believe that I'm using version 4.3.1

[stephanwlee]

I meant TensorBoard 1.12. https://pypi.org/project/tensorboard/1.12.0/

[bwang12]

I am using TensorBoard 1.12.2 and I am receiving the same error. I should add that I am using a workspace machine that I do have admin access to.

What's different is that Chrome (Version 71.0.3578.98 (Official Build) (64-bit)) refuses to even connect to TensorBoard, giving a This site can't be reached error.
On Internet Explorer (Version: 11.0.9600.19236CO), the page name would show up as TensorBoard but nothing is displayed in the body.

And only when trying to access TensorBoard on Internet Explorer would result in new error log in cmd window:

(base) C:\Users\bwang>tensorboard --logdir =/tmp/summaries

maybe you need to type a dot before the slash
tensorboard --logdir=./output --host localhost --port=6006

[huxl5]

you can try to use Chrome
