The line is “wandb: / 0.000 MB of 0.010 MB uploaded (0.000 MB deduped)”!
The problem occurs after i use “ctrl+c” to abort syncing. 
Hey @wangpu19990606, thanks for raising this! When you do Ctrl+C, it might take some time to finish the process if it’s a large one but doing Ctrl+C again or waiting for some time should help
