Visdom Always Offline

I cloned visdom, installed from source (using pip install -e .) and then also ran (python setup.py install) to finish the installation (visdom==0.1.7.2). I started up the server (python -m visdom.server) and was able to bring up visdom in Chrome but it remains offline.

I can only click on the two dropdowns and when I click on “main”, the following error prints out:

The javascript console then has the following error:

WebSocket connection to 'ws://localhost:8097/env/socket' failed: Error during WebSocket handshake: Unexpected response code: 200 WrappedWebSocket@VM518:164

When I try to run the code example:

>>> import visdom
>>> import numpy as mp
>>> vis = visdom.Visdom()
>>> vis.text('Hello, world')
'window_36084c0e4eddf6'

The following is output but nothing shows up in visdom.

INFO:root:Opened visdom socket from ip: ::1
INFO:tornado.access:200 POST /events (::1) 0.85ms

The javascript console then has the following error:

Are there setup steps that I missed?

Yeah that’s somewhat related to https://github.com/facebookresearch/visdom/issues/273, the feature used to work properly so the docs had prepopulated an empty env but I haven’t had a chance to fix the env access by path yet. Thanks for noting it!

Ahh, yup, thats the problem, I went to localhost:8097/env (based on some docs I’ll update). When I went to just localhost:8097 then it works as expected, thank you!
