In the rapidly evolving world of artificial intelligence, being at the forefront means embracing innovative models that can process diverse inputs. The Otter model brings the power of multi-modal instruction tuning to life, especially using the MIMIC-IT dataset. This guide will walk you through setting up and training the Otter model, ensuring you can fully utilize its capabilities.

Step-by-Step Setup

1. Prerequisites: Ensure you have a suitable GPU with at least 16GB memory. Develop a Python environment tailored for this task.
2. Install Dependencies: Use conda to create your environment with the provided environment.yml file, emphasizing the right versions of libraries like transformers and accelerate.
3. Download the Model Weights: The weights for the Otter model can be accessed [here](https://huggingface.co/luodianOTTER-MPT7B-Init) and [here](https://huggingface.co/luodianOTTER-9B-INIT).

Running the Model Locally

To run the Otter model locally, you must adjust the system path correctly to access otter.modeling_otter. Follow these steps:

1. Clone the repository from GitHub.
2. Navigate to the directory and ensure all paths are set up correctly.
3. Launch the model using the appropriate Python script.

Training the Otter Model

The Otter model is trained on data from the MIMIC-IT dataset. Organizing your training data correctly is crucial for model performance. Here’s how to set it up:

export PYTHONPATH=.
RUN_NAME=Otter_MPT7B
GPU=8
WORKERS=$(($GPU*2))
echo Using $GPU GPUs and $WORKERS workers
echo Running $RUN_NAME
accelerate launch --config_file=.pipeline/accelerate_configs/accelerate_config_zero3.yaml \
    --num_processes=$GPU \
    pipelinetraininstruction_following.py \
    --pretrained_model_name_or_path=luodianOTTER-MPT7B-Init \
    --model_name=otter \
    --instruction_format=simple \
    --training_data_yaml=.shared_scripts/Demo_Data.yaml \
    --batch_size=8 \
    --num_epochs=3 \
    --report_to_wandb \
    --wandb_entity=ntu-slab \
    --external_save_dir=.checkpoints \
    --run_name=$RUN_NAME \
    --wandb_project=Otter_MPTV \
    --workers=$WORKERS \
    --lr_scheduler=cosine \
    --learning_rate=2e-5 \
    --warmup_steps_ratio=0.01 \
    --save_hf_model \
    --max_seq_len=1024

Explaining the Code with an Analogy

Imagine you’re a chef preparing a gourmet meal.

• The ingredients you choose are similar to the various datasets used for training—each dataset adds a unique flavor to the final dish.
• The cooking instructions resemble the code you run in training—these steps guide you to combine ingredients in a way that brings out the best result.
• The stove settings are akin to the learning rate and epochs; getting them just right is key to achieving that perfect cook. Too high, and you risk burning your dish; too low, and it may not cook through.

In short, just as a great chef pays close attention to their recipe, so should you when configuring and running your training code!

Troubleshooting

Should you encounter issues while setting up or running the Otter model, consider these troubleshooting steps:

• Check the compatibility of your CUDA version using nvidia-smi and nvcc --version. They should match.
• Ensure you have all the necessary Python packages installed as per the environment.yml.
• Verify the path settings are correctly set to access the required modules!
