Failed to establish a new connection:[Errno 111] connection refused #129
requests.exceptions.ConnectionError: HTTPConnectionPool(host='localhost', port=8889): Max retries exceeded with url: /env/main (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f1ca74fb208>: Failed to establish a new connection: [Errno 111] Connection refused',)). Basically, visdom error. It seems visdom error is from bug.
python -m visdom.server
The visdom display functionality is turned on by default. To avoid the extra overhead of communicating with visdom set --display_id 0.
If you want to use the visdom server, you should change the display_id to a non-zero value. To view training results and loss plots, run python -m visdom.server and click the URL http://localhost:8097.
added "--display_id 0" running train.py but I still get this error
example: when I training GP-GAN
(Paper: GP-GAN: Gender-Preserving-GAN-for-Synthesizing-Faces-from-Landmarks )
(source code: https://github.com/DetionDX/GP-GAN-GenderPreserving-GAN-for-Synthesizing-Faces-from-Landmarks)
(training command: python train.py --dataroot ./datasets/lfw/ --which_direction BtoA --fineSize 64 --loadSize 64 --no_flip --name lfw_gpgan)
When I alone run the training command there is a error : Failed to establish a new connection:[Errno 111] connection refused
So I modified the command by adding "--display_id 0" in end of previouse training command that result in it become: python train.py --dataroot ./datasets/lfw/ --which_direction BtoA --fineSize 64 --loadSize 64 --no_flip --name lfw_gpgan --display_id 0
It run successfully
However, if you results are not so good that you are satisfied you can continue training
Adding "--continue" in the end of the training command like this:
python train.py --dataroot ./datasets/lfw/ --which_direction BtoA --fineSize 64 --loadSize 64 --no_flip --name lfw_gpgan --continue
