Hello, dr

I test this code in ubuntu and it works pretty well, but when I try it on win10 with the same python env, i meet some problem:

`Could not connect to Visdom server. Trying to start a server.... Command: D:\SDKs\Python\Anaconda\envs\cut\python.exe -m visdom.server -p 8097 &>/dev/null & create web directory ./checkpoints\singleimage_monet_etretat\web...

Python envs: Python = 3.6.12 pytorch=1.4.0 torchvision==0.5.0 visdom==0.1.8 packaging GPUtil==1.4.0

it seems to visdom does not work well. Could you please tell me how to solve this problem? Thanks!

I had the same problem. It's related to pytorch windows thread issues. To solve go to data/__init__.py and change the number of worker threads (line 79).

            self.dataset,
            batch_size=opt.batch_size,
            shuffle=not opt.serial_batches,
            # num_workers=int(opt.num_threads), This is the problem, change it to 0
            num_workers = int(0), 
            drop_last=True if opt.isTrain else False,`

Thanks！ Solved!
