I test the code on Windows. How can I run the "train.py" in Windows. Attached please find the issue:

Same question. Thank you.

[junyanz]

Please refer to this Q & A.

[guotong1988]

Thank you very much!!! I have seen the link of 17 Oct 2018

@frogprincel @guotong1988 @junyanz I have the same question. However, I am not sure how to handle the visdom server.

I am using the docker container and if I execute

python -m visdom.server

the server starts as expected however, I am not sure how to continue. I can either enter something in the command line but it is not working nor stopping the visdom server. Could you please provide the order in which I have to call the functions?

Thanks a lot in advance!!!

[junyanz]

You need to run python -m visdom.server in a separate command panel. You can also run it as a background program.

[paviddavid]

@junyanz Thanks for your quick response.

I am working within your docker container. Is it necessary to start the visdom.server command from inside the docker container or is it ok to run it from another terminal?

(If I should run it inside a docker container, how do I get start two docker instances with the same image?)
Thanks a lot in advance for your support and best regards

[junyanz]

I haven't used docker that much. I leave your question to @taesungp

[paviddavid]

@junyanz Thanks a lot for your help. Hope @taesungp could give me some hints for this..

[paviddavid]

@junyanz (and everybody who might have the same problem)
Start a docker container as described in the repo. In a second terminal window, you should run docker exec -it <image name> bash. There it is possible to run the python -m visdom.server command as described and it works as expected.
