Scalar plots are empty, log_scalar values only appear on experiment overview

[stocyr]

• Plots of any log_metric are empty, though the latest logged scalars do appear in the experiment overview table and the compare panel as single float values.

Setup:

• Windows 10
• Deepkit Release 2020.1.5
• Deepkit SDK 1.0.1
• Python 3.7.x (running local or remote)

@stocyr What do you mean with log_scalar? We don't have such a method. Can you please provide the source lines? Could you please also provide screenshots (of the experiment overview list vs experiment detail view)?

I updated the post above. Here's the snipped of the code:

import deepkit

def train(args, model, device, train_loader, optimizer, epoch):
    # ...
    for batch_idx, (data, target) in enumerate(train_loader):
        data, target = data.to(device), target.to(device)
        optimizer.zero_grad()
        output = model(data)
        loss = F.nll_loss(output, target)
        loss.backward()
        optimizer.step()

        _, predicted = output.max(1)
        total += target.size(0)
        correct += predicted.eq(target).sum().item()

        args.experiment.log_metric('loss/train', loss.item(), x=epoch + (batch_idx / len(train_loader)))

def main():
    # ...
    args = parser.parse_args()
    experiment = deepkit.experiment()
    args.experiment = experiment
    # ...
    for epoch in range(1, args.epochs + 1):
        args.experiment.epoch(epoch, args.epochs)
        train(args, model, device, train_loader, optimizer, epoch)

if __name__ == '__main__':
    main()

The effect can be seen here on the running experiment (top most)

And here's what happens if I pull the "smoothing" slider a little:

update
I recently noticed that the plots show up when the Deepkit App is connected to a remote-hosted Team Server (eg. a non-localhost account). So the bug only appears to happen on the localhost connected app.

That's interesting. Seems to be a windows issue. Can you open the devtools to see if there are any errors? STRG+SHIFT+I, then "console" tab.
