Connection Error:HTTPConnectionPool

[YushengZhang]

When I try to python the train.py, such error will show up:
Traceback (most recent call last):

I have tried to modify the requests.adapters.DEFAULT_RETRIES from 0 to 5, but also set requests.session().keep_alive to False.However it doesn't work.How can I successfully run the train.py?

I also meet this problem . Do you solve it ?

[YushengZhang]

Not yet,I'm going to python another CycleGAN code

[YushengZhang]

Finally I have found the answer!
"start the visdom server before starting the training

python -m visdom.server
"
And the code can run.

Wow，so great ! it works 👍 😄

@YushengZhang
start the visdom server before starting the training:
python -m visdom.server
It works! Thanks a lot!

You can also set the --display_id 0 if you don't want to use visdom

[zikai1]

python -m visdom.server python train.py
then I start python train.py
It start works!

I am facing a similar issue. I do not know how to handle the visdom tool.
Starting the server by python -m visdom.server works (more or less) as expected - no error message, everything starts and I see a blue screen in localhost:8097
However, how should I go on?

I can enter something in the same terminal window (where I started the server) but nothing happens. Should I close it before I can go on?

I am using the docker image provided in the repo.

Sorry for the confusions and thanks a lot in advance!!
