Pytorch-cyclegan-and-pix2pix: socket.error: [Errno 111] Connection refused

[Tenacity-soar]

when i run the Pix2Pix
"python train.py --dataroot ./datasets/facades --name facades_pix2pix --model pix2pix --which_model_netG unet_256 --which_direction BtoA --lambda_A 100 --dataset_mode aligned --use_dropout --no_lsgan"

a problem happened as follow:

how to solve the problem?

[junyanz]

Please install the visdom library, and run the following command python -m visdom.server. Please see more details in training/test details.

[Tenacity-soar]

thank you very much. But i have not solve the problem, i have run the command python -m visdom.server. I set the --display_id = 1. I open the http://localhost:8097, nothing in the html.
So i need your help.
Thank you very much! And what should i do next?

[Tenacity-soar]

Should i run the command http://localhost:8097/env/1 ?

[junyanz]

It might be related to the data_loader. Could you try set --nThreads 1 and see what will happen?

[Tenacity-soar]

Thank you. I set --nThreds 1, but the same problem happened again.

[Tenacity-soar]

And I run another dataset edges2shoes. No problem happend.

[sadkangaroo]

I was running with CPU and had the same problem. Setting --nThreads 0 and --display_id 0 solved the problem for me.

[Tenacity-soar]

Thanks, I use your ways . And I have solved the problem. Thank you very much.

[aidandan]

I have the same bug,,when I setting --nThreads 0 and --display_id，，，DoI need to run the program after the file changes, such thatpython base_options.py` ? I am note sure the run sequence .

Solved by expand shared memory.
