Visdom: Connection timed out : when using python -m visdom.server
Hi, when I use
python -m visdom.server
to start visdom server, I got Connection timed out error as following:

I am a new one for pytorch and visdom. I would like to use visdom for visualization. I use anaconda2, python3.6 as default setting. What should I do? Thanks a lot !

Visdom downloads some external JS dependencies at server start-up time. It looks like those downloads fail for you. Do you need a proxy to be able to access public URLs from your machine?

Thanks for your suggestion . However, It seems that I don' t need a proxy, since another machine is able to run the visdom server normally with the same Internet setting as mine. Is there any possible for other problems ? Thanks a lot.

Still, if your urllib module is up to date it would seem at least one of the packages must be failing, though it's hard to say which one. Can you list the contents of your /root/anaconda2/envs/gtn_env/lib/python3.6/site-packages/visdom/static directory and sub directories?

Thanks for reply. The directory "............../static" contains :
css fonts index.html js
The directory "............../static/js" contains:
bootstrap.min.js jquery.min.js main.js react-dom.min.js react-react.min.js
Does it help ?

Is there anything at all in fonts or css? If not it would appear the first thing missing in the order of things downloaded belongs in the font folder, namely the script downloaded by visdom from https://unpkg.com/[email protected] and stored as visdom/static/fonts/classnames. If nothing is in your fonts directory can you download that file manually, save it as classnames, and put it in the static/fonts directory before continuing? Then see if more files populate?
JackUrb

I have checked the static/fonts directory. It contains:
classnames layout_bin_packer
In "classnames" , it is commented at top as following:
Copyright (c) 2016 Jed Watson.
Licensed under the MIT License (MIT), see
http://jedwatson.github.io/classnames
I am not sure if it is dowloaded from https://unpkg.com/[email protected].
Do I still need to download that file manually as you say ?
huoliangyu
on 30 Oct 2017
No that's the correct file. It seems all the unpkg.com files from the first batch download then. Based on what you've listed the first file you're getting stuck on is https://cdn.rawgit.com/STRML/react-grid-layout/0.14.0/dist/react-grid-layout.min.js, which should be saved as visdom/static/js/react-grid-layout.min.js. Do you have this file?
JackUrb
on 30 Oct 2017
NO, I don' t have this file. So I need to dowload this file manually, from https://cdn.rawgit.com/STRML/react-grid-layout/0.14.0/dist/react-grid-layout.min.js and save it as visdom/static/js/react-grid-layout.min.js. Is that correct?
huoliangyu

Correct, then try to start the server again and see if it makes it to running. In general as you run into problems with CDNs, the order that visdom downloads and saves files is as follows:
download from https://unpkg.com/[email protected]/dist/jquery.min.js
and put at visdom/static/js/jquery.min.js
download from https://unpkg.com/[email protected]/dist/js/bootstrap.min.js
and put at visdom/static/js/bootstrap.min.js
download from https://unpkg.com/[email protected]/css/styles.css
and put at visdom/static/css/react-resizable-styles.css
download from https://unpkg.com/[email protected]/css/styles.css
and put at visdom/static/css/react-grid-layout-styles.css
download from https://unpkg.com/[email protected]/dist/react.min.js
and put at visdom/static/js/react-react.min.js
download from https://unpkg.com/[email protected]/dist/react-dom.min.js
and put at visdom/static/js/react-dom.min.js

If you run the server and it hangs on downloading, you can download the next missing file yourself (based on the last file in the list you can confirm having)

It works for me. Thank you very much !

@JackUrb How to download https://unpkg.com/[email protected]? Is this a file?
https://unpkg.com/[email protected]/index.js?

@JackUrb Yes, it's a js file. And following your instructions, I solved this problem. Thank you very much.

hello,this link https://cdn.rawgit.com/STRML/react-grid-layout/0.14.0/dist/react-grid-layout.min.js seems have some errors. Can you share me all of the files in visdom/static? Thanks very much!

Thank @JackUrb . I changed the download link to a shell command with a text replacement:

@logic1988 thanks for the suggested conversion - I'll update the docs with this (as in the best case it automates the download and in the worst case if someone can't wget through their proxy it's no worse than the copy-paste it was before)

I meet the same problem. It is stuck at downloading the file visdom/static/js/react-grid-layout.min.js from the link https://cdn.rawgit.com/STRML/react-grid-layout/0.14.0/dist/react-grid-layout.min.js. The problem occurs in the version 0.1.6 of visdom. The problem is resolved with the version 0.1.5.

Hi @sergeywong - a fix for this was added to the github recently and I just pushed it to pypi. Try using version 0.1.6.5
