visdom shows nothing

[y406539259]

I am very confused that I tried the demo.py but showed nothing at http://localhost:8097
The server has received the message but shows nothing, the web explorer only shows blue background, It has no other windows.

Same on python3.6, it used to be OK.

Same on python2.7 ubuntu 14,04

Hmm. Can you surface the Developer Console in your browser and post any error messages that show up on the browser end? With Chrome you can get this in 'View'->'Developer'->'Javascript Console'.

[zengyu714]

(index):24 GET https://cdn.rawgit.com/STRML/react-grid-layout/0.14.0/dist/react-grid-layout.min.js net::ERR_CONNECTION_TIMED_OUT
(index):28 GET https://cdn.rawgit.com/plotly/plotly.js/master/dist/plotly.min.js net::ERR_CONNECTION_TIMED_OUT

This time-out error could be solved by proxy, and then visdom is normal again.
Thank @ajabri for providing a way to check errors.

Thanks to the GREAT Firewall in China. 👎

Would you please give some instructions on how to use proxy to solve this? @zengyu714

[zengyu714]

That is, use your VPN. 2017-08-10 11:29 GMT+08:00 yukang2017 <notifications@github.com>:

I don't think it can be solved by VPN. Sometimes I use VPN, and visdom works; sometimes I don't use VPN, and Visdom works. But sometimes I use VPN, and Visdom do not work. @zengyu714

btw, it seems that you and me have a same name 'zeng yu' 😃

[yukang2017]

@zengxianyu
change py/init.py,line 206 server='http://localhost' to
server='127.0.0.1'
then resetup visdom using:
python setup.py install

It works for me without VPN

[zengxianyu]

It does not work for me 😢 @yukang2017

[yukang2017]

When using it, go to the address : 127.0.0.1:8097 instead of http://localhost:8097.

The reason is the web browser can not find plotly and react-gird-layout through internet
My idea is download these two packages and change the search path of them in index.html of visdom.

So I downloaded
1, plotly.js: https://github.com/plotly/plotly.js
2, react-gird-layout: https://github.com/STRML/react-grid-layout

And put them in
python2.7/site-packages/visdom/static/js/

And I added the search path of them in:
python2.7/site-packages/visdom/static/index.html

So the web browser can find them locally.

<!-- Other deps -->
<script src="https://unpkg.com/react@15/dist/react.min.js"></script>
<script src="https://unpkg.com/react-dom@15/dist/react-dom.min.js"></script>
<script src="https://unpkg.com/classnames@2.2.5"></script>
<script src="https://unpkg.com/layout-bin-packer@1.2.2"></script>
<script src={{ static_url("js/react-grid-layout-master/dist/react-grid-layout.min.js") }}></script>

<!-- Mathjax -->
<script type="text/javascript" async src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_SVG"></script>

<!-- Plotly -->
<script src={{ static_url("js/plotly.js-master/dist/plotly.min.js") }}></script>

Finally, it works and do not need to use a VPN.

@zengyu714 I met many issues concerning visdom since March. This is one of it. Sometimes I am lucky to load the page, sometimes I got blank blue page. But I had never been considering this as an error. Presently, I add CDS into proxy rules, it works fine now.

[Gerkam]

I have same problem, but I have a proxy on own machine. I tried to copy locally js libs, but see this logs on js console.

How I can solve this problem?

[lvdmaaten]

Please manually download and install the dependencies per the instructions in https://github.com/facebookresearch/visdom/blob/master/CONTRIBUTING.md

[ningkyan]

Sometimes, when there is a proxy setup in environment, it will make visdom only display a blue screen. I found that setting os.environ['http_proxy'] = '' solves this case. Hope this could help.

[masoodmortazavi]

Without a proxy setting, sometimes visdom server gets stuck expecting something (javascripts?) to be downloaded. With proxy settings it completes start up but it then later runs into the problems mentioned above -- only showing the results upon a reload, and then going into a full blue screen.

[JackUrb]

@masoodmortazavi does anything appear in the javascript console or the python server logs when you're running into this issue?

[masoodmortazavi]

Comparing the already-downloaded javascript files in the pip installation in Python virtual environment with those specified in visdom's "download.sh" on this git repository, and then using wget over proxy to download missing javascripts into the corresponding folder, fixed the problem. (There should be no OS level http proxy or https proxy settings. This does cause problems. The javascripts should be downloaded with wget -- just like specified on download.sh -- but with proxy settings set up for the wget process that does each download individually.)

[masoodmortazavi]

@masoodmortazavi does anything appear in the javascript console or the python server logs when you're running into this issue?
visdom server simply waits to download missing javascript when no system level proxy is available. I did mention how I fixed this issue in the message I just posted.

[rishikadhanawade]

I tried all the above-mentioned solutions but still, the error is not getting solved. What else should I do?

[lvdmaaten]

Are you sure there is no proxy between your visdom server and the code generating the visualization, or between the server and the machine on which you are looking at the visdom dashboard? Behavior like this is most commonly caused by some proxy configuration blocking traffic.

Do you see any errors in the JavaScript Console? (In Chrome: View -> Developer -> JavaScript Console.)

[lvdmaaten]

Can you please copy-paste the errors you see here?

[rishikadhanawade]

Uncaught :2019/extensions/MathMenu.js?V=2.7.1:2
Uncaught SyntaxError: Unexpected number
MathZoom.js:2 Uncaught SyntaxError: Unexpected number
I am getting these two errors in the javascript console.

This works for my Mac, python 3.6, torch 1.0, visdom 0.1.8.9

[leopardyao]

Visdom : blue screen (or with white tool bar but I cannot see anything plot in screen)
hello, I am in a company internet and with a proxy.
windows 10+ visdom 0.1.8.9
With proxy set up, I was able to successfully downloaded necessary static files, but getting the warnings when run vimserver from command line:
WARNING:tornado.access:404 GET /static/js/layout-bin-packer.js.map (::1)
WARNING:tornado.access:404 GET /static/css/bootstrap.min.css.map

if checked develop tools , it also shows
DevTools failed to load SourceMap: Could not load content for http://localhost:8097/static/js/layout-bin-packer.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE
DevTools failed to load SourceMap: Could not load content for http://localhost:8097/static/css/bootstrap.min.css.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

click into the above http will show tornado web.py 404 problem.

I understand this might be due to some proxy but how should I fix them?
what i have tried , but is not working:
(1) replace my downloaded static folder with some offline downloaded static folder posted by other people. not working
(2) following above comments set os.environ['http_proxy'] = '' (I put it in server.py)

What are js.map or css.map file do i really need to find and download them?

thanks

--Editted on 05/18--
I searched on google and downloaded the .map files in my css/js folders
now the 404 warnings are gone, besides some unexpected number syntax error from math (are these errors important? I found in some other post it is not relevant)

I can see the white menu bar though ( view, enviroment bar)
however, I still cannot see anything plot, nor can I change the enviroment.

[JackUrb]

@leopardyao The contents of your image suggest that visdom is now running correctly. If you run the demo you should either see plots or potentially errors in the server logs if not.

Thanks JackUrb.
It turns out it is still the proxy issue. Following the suggestions by ningykan, I removed my http_proxy setting in env variables and now it is working. (although sometimes it may need to restart the computer).

I am curious why this happens? After downloading all necessary static files, why Proxy setting still matters for visdom? As a few people are having the issues, can we add this as an option in future versions when staring visdom server from the command?
Thanks!

Hi! I get into the same trouble. Could you please tell me how to find some offline downloaded static folder to replace the online one?

[libo-huang]

maybe you need to update a newer version of visdom package.
