Description

#!/usr/bin/env python
"""main."""
import wandb
from torch.utils.tensorboard.writer import SummaryWriter

model = image_models["mbt2018"](pretrained=True, quality=6)

log_dir = '/output/logs'

name = '5'
wandb.init(project="my-test-project-2", dir=log_dir, name=name, id=name,
           config={"learning_rate": 0.001, "epochs": 100, "batch_size": 128},
           sync_tensorboard=True)

writer = SummaryWriter(log_dir=log_dir)

writer.add_scalars('metrics/loss', {'train': 20, 'val': 100}, 0)
writer.add_scalars('metrics/loss', {'train': 10, 'val':  50}, 1)

# Optional
wandb.finish()

Can it display curves of same tag to one graph?

This is wandb:

This is tensorboard:

Hi @Freed-Wu,

Yup, this is already possible. You can read about it in our docs here : https://docs.wandb.ai/ref/app/features/panels/line-plot#compare-two-metrics-on-one-chart

Can it support tensorboard's add_scalars?

Hey @Freed-Wu,

Yes, add_scalar from tensorboard is supported.

I mean can it display multi curves in one graph like add_scalars?

That is how can wandb display similar result with tensorboard? #4449 (comment)

Hey @Freed-Wu,

As I mentioned before, multiple curves are already supported. You will have to do some manual work to get these exactly the way you need them however. Here is a video to aid you with how to do this for any 2 plots:

Is it possible to do this automatically? Manually fiddling isn't ideal when many metrics are logged. It also liters workspace and requires deleting 'standalone', ungroupped graphs. It would be nice if logging a dict (with maybe additional flag group to not break things) would group things automatically as OP showed.

I agree that this should be done automatically, since it's impractical and error prone to do this for every single figure. Especially when dealing with more than two curves. Suggested solution: copy tensorboard's functionality.

I would also agree that it would be nice to do this automatically.

Is there an update on this? I would also love this functionality.

This is also already done for system metrics like GPU power usage for multi-gpu runs. Can't we do the same for other metrics?

I tried to look in the wandb code to see how these system metrics are reported, but couldn't see anything useful for reporting other metrics similarly. Also not sure if these System metrics are just special-cased in the UI.
