Hi,

There's logging for Visdom enabled by default. Make sure that visdom is running using sudo python3 -m visdom.server before training.

[yellowtownhz]

The problem is solved. It's weird. I knew i forgot to run visdom the first time i ran the code. So i ran sudo python3.5 -m visdom.server, then i got a similar output just as above. i suppose maybe all i need to do is to restart the terminal....... anyway, thank u so much for ur help!~ haha ~

[iwasaki-kenta]

No problem :)
