TimelyPenguin76 It help me! Thank

Hi ItchyHippopotamus18 ,

it seems the request does not reach the Trains File Server (port 8081, same machine running Trains Server), can you reach it?

TimelyPenguin76 SuccessfulKoala55 Thank you. I found an error, the wrong port was specified. Now I don't have a display of saved models in the 'models'tab. I save it like this:
` model_jit = torch.jit.trace(model, torch.ones(1, 3, 480, 480).to('cuda'))

model_jit.save(os.path.join(checkpoint_path, f'{epoch_num}_{round(acc_full, 4)}.pt')) `

Hi ItchyHippopotamus18 ,
Try browsing to http://koala03.ftc.ru:8081/ in your browser - it should result in an error, but the type of error will indicate if you can reach it or not.
Also, it would be nice to see the entire error line (the screen shot shows only part of the error)

TimelyPenguin76 How I can check File Server? Web Server http://koala03.ftc.ru:8080/ work good

Hi  ItchyHippopotamus18  , can you try with
torch.save(model_jit, os.path.join(checkpoint_path, f'{epoch_num}_{round(acc_full, 4)}.pt'))?
