Composer

What's New

**1. Aggregate Memory Monitoring (3042)**

The Memory Monitor callback now supports aggregating memory statistics across nodes. Getting summary stats for a run's memory usage across the cluster can dramatically help debug straggler nodes or non-homogenous workloads. The memory monitor can now aggregate and log combined values at a user specified frequency.

Example:

from composer import Trainer
from composer.callbacks import MemoryMonitor

trainer = Trainer(
model=model,
train_dataloader=train_dataloader,
optimizers=optimizer,
max_duration="1ep",
callbacks=[
MemoryMonitor(
dist_aggregate_batch_interval=10, aggregate every 10 batches
)
],
)


**2. Advanced Compression Options (3118)**

Large model checkpoints can be expensive to store and transfer. In this release, we've upgraded our compression support to accept several new formats which result in better compression-time tradeoffs using CLI tools. In order to use compression, you can post-fix your checkpoint name with a compression path. We know support the following extensions:
- bz2
- gz
- lz4
- lzma
- lzo
- xz
- zst

Example:

from composer import Trainer
from composer.callbacks import MemoryMonitor

trainer = Trainer(
model=model,
train_dataloader=train_dataloader,
optimizers=optimizer,
max_duration="1ep",
save_filename='ep{epoch}-ba{batch}-rank{rank}.pt.lz4',
)


Thank you to mbway for adding this support!

**Full Changelog**: https://github.com/mosaicml/composer/compare/v0.20.1...v0.21.0

What's New

1. Torch 2.2.1 Support

Composer now supports torch 2.2.1! We've raised the pin to allow the latest torch, and we've upstreamed all torch monkeypatches so Composer can run out of the box with the latest and greatest torch features.

What's Changed
* Add torch 2.2.1 support by mvpatel2000 in https://github.com/mosaicml/composer/pull/3059
* Bump version to 0.20.1 by mvpatel2000 in https://github.com/mosaicml/composer/pull/3061

What's New

1. New Neptune Logger
Composer now supports logging training data to [neptune.ai](https://neptune.ai/) using the `NeptuneLogger`. To get started:

python
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](https://app.neptune.ai/o/showcase/org/mosaicml-composer/runs/details?viewId=standard-view&detailsTab=dashboard&dashboardId=9b1f1fae-f543-41d1-a778-8604c9b6503d&shortId=MMLCOMP-3) demonstrating all the awesome things you can do with this integration!


Additional information on the `NeptuneLogger` can be found in the [docs](https://docs.mosaicml.com/projects/composer/en/latest/api_reference/generated/composer.loggers.NeptuneLogger.html).


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:
python
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",
)
],
)


OOM Visualization:



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

**Full Changelog**: https://github.com/mosaicml/composer/compare/v0.19.1...v0.20.0

What's New

**1. New Event: BEFORE_LOAD (2974)**

Composer now has the events `Event.BEFORE_LOAD`, which lets users modify state before a model is loaded. This is particularly useful for accessing certain attributes which may not exist at `Event.INIT`, such as the dataloader state.

**2. Registering model in MLFlow with run id (2967)**

The MLFlow logger now has `register_model_with_run_id`, which allows users to register a model based on the run_id. This is a different way of registering the model which preserves the link to the mlflow runs.

What's Changed
* before_load event added https://github.com/mosaicml/composer/pull/2974
* Add a register_model_with_run_id api to MLflowLogger https://github.com/mosaicml/composer/pull/2967

**Full Changelog**: https://github.com/mosaicml/composer/compare/v0.19.0...v0.19.1

What's New

1. Improved DTensor Support
Composer now supports elastic saving and loading of DTensors at various mesh sizes.

2. Checkpoint Saving and Loading from Databricks MLFlow
Composer now supports saving and loading checkpoints to Databricks-managed MLFlow.


composer_model = MyComposerModel(...)

trainer = Trainer(
model=composer_model,
save_folder= 'dbfs:/databricks/mlflow-tracking/{mlflow_experiment_id}/{mlflow_run_id}/artifacts',
logger=MLFlowLogger(...),
load_path= 'dbfs:/databricks/mlflow-tracking/{mlflow_experiment_id}/{mlflow_run_id}/artifacts',
...
)

3. Better Communication Computation Overlap in FSDP
Composer now has improved communication/computation overlap in our FSDP code which should improve MFU across several architectures.

4. Python3.11 + Torch2.2 Support
Initial support of Python3.11 + Torch2.2 added in Composer.

5. PEFT LoRA
PEFT LoRA is now supported in the HuggingFaceModel class.

6. Refactored Evaluation
`in_context_learning_evaluation.py` has a new design with cleaner abstractions and easier interfaces to work wtih.

7. Azure Checkpointing
Composer now supports saving your model in Azure.

8. MLFlow Checkpointing
Composer now supports saving your model in MLFlow.
