## What does this PR do?
**Type of change:** New Feature <!-- Use one of the following: Bug fix,
new feature, new example, new tests, documentation. -->
**Overview:**
- Supported Context Parallel by patching torch ring attention;
- Require following libirary version for stable cp:
- torch2.8.0
- transformers5.0.0
- accelrate1.12.0
- Move to FSDP2
- Removed unused arguments in training script (`--multi_gpu`,
`fsdp_wrap_layer`)
- Bump CI container to `nvcr.io/nvidia/pytorch:25.08-py3`
## Usage
<!-- You can potentially add a usage example below. -->
```bash
./launch_train.sh --model $MODEL \
--output_dir $OUTPUT_DIR \
--data $DATA \
--num_epochs 0.1 \
--train_bs 1 \
--eagle_config eagle_config.json \
--training_seq_len 1024 \
--cp_size 2 #newly added
```
## Testing
- SDPA level correctness: tested TTT attention with/without CP, diff <
1%
```

Model Optimizer End-to-End Tests
This directory contains end-to-end tests for the Model Optimizer's examples.
Adding new tests
To add a test for a new example, create a new example directory in tests/examples following the existing examples as guidance.
Make sure to use as small models and less data as possible to keep the tests fast. Unless needed, have tests finish under 15 minutes.
Running the tests
To run a test, start from the recommended docker image from our installation docs.
Then mount your local modelopt directory to /workspace/Model-Optimizer and run this from the root of the repository.
cd /workspace/Model-Optimizer
pip install -e ".[all,dev-test]"
pytest tests/examples/$TEST
Environment variables
The following environment variables can be set to control the behavior of the tests:
MODELOPT_LOCAL_MODEL_ROOT: If set, the tests will use the local model directory instead of downloading the model from the internet. Default is not set, which means the model will be downloaded.
