Visdom: HTTPConnectionPool for python

[onlytailei]

When I try

import visdom
import numpy as np
vis = visdom.Visdom()
vis.text('Hello, world!')
vis.image(np.ones((10, 10, 3)))

I got this:

Traceback (most recent call last):

Actually the first time I launched the web successfully. But after that it cannot work anymore even I restart the computer.

Sorry... Forget to start the server....

[soldier828]

Thank you! I'm new here. And didn't realize to start the server.

I received the same error. I run python -m visdom.server in my terminal in ipython but I received invalid syntax error..
should I run this command somewhere else?

Thanks

You should run the python -m visdom.server command from your terminal, not in the python REPL. Make sure the server is running, so start in it a separate terminal window (potentially using screen or tmux)

I started the server using python -m visdom.server -p 7777 and was able to open it in the browser,

but when trying

import visdom, numpy as np
vis = visdom.Visdom()
vis.text('hello')

I get the following error:

please help

[lvdmaaten]

You should make your client connect to the correct port: vis = visdom.Visdom(port=7777).

[udion]

Thanks,
also while running the demo script I get an error

is this attribute not available yet through pip (I installed visdom using pip)

[JackUrb]

Hi @udion - Yeah I haven't updated the pip package just yet, sorry! Doing so now

[zhaopanpan73]

when I start the server.then it happens

I don't know what the "scripts" refers to ?

[JackUrb]

Every time the server runs it checks to see if it needs to download additional scripts for the frontend and then it does the downloads. This is normal behavior.

[zhaopanpan73]

@JackUrb But my computer can't connect to the internet by school's config. In this situation,what should I do to make the server run properly

[JackUrb]

@zhaopanpan73 You can download the scripts elsewhere using the download.sh script, and then copy them over to the proper locations.
