What's New

1. New Neptune Logger

Composer now supports logging training data to neptune.ai using the NeptuneLogger. To get started:

neptune_project = 'test_project'
neptune_api_token = 'test_token'

neptune_logger = NeptuneLogger(
    project=neptune_project,
    api_token=neptune_api_token,
    rank_zero_only=False,
    mode='debug',
    upload_artifacts=True,
)

We also have an example project demonstrating all the awesome things you can do with this integration!

Additional information on the NeptuneLogger can be found in the docs.

2. OOM observer callback with memory visualizations

Composer now has an OOM observer callback. When a model runs out of memory, this callback helps produce a trace which identifies memory allocations, which can be critical to designing strategies to mitigate memory usage.

Example:

from composer import Trainer
from composer.callbacks import OOMObserver
# constructing trainer object with this callback
trainer = Trainer(
    model=model,
    train_dataloader=train_dataloader,
    eval_dataloader=eval_dataloader,
    optimizers=optimizer,
    max_duration="1ep",
    callbacks=[
        OOMObserver(
            folder="traces",
            overwrite=true,
            filename="rank{rank}_oom",
            remote_filename="oci://bucket_name/{run_name}/oom_traces/rank{rank}_oom",
        )
    ],
)

3. Log all gpu rank stdout/err to MosaicML platform

Composer has expanded it's integration with the MosaicML platform.. Now, we can view all gpu rank stdout/stderrs with MCLI logs to enable more comprehensive analysis of jobs.

Example:

mcli logs <run-name> --node x --gpu x

Note, this defaults to node rank 0 if --node is not provided.

Also, we can find the logs of any global gpu rank with the command:

mcli logs <run-name> --global-gpu-rank x
