Installation

TPU Training

If you’re aiming to train on TPU using TorchXLA, follow these steps:

1. Clone the repository and navigate to the codebase:

bash git clone https://github.com/cambrian-mllm/cambrian
cd cambrian

2. Install the necessary packages:

shell
conda create -n cambrian python=3.10 -y
conda activate cambrian
pip install --upgrade pip  # enable PEP 660 support
pip install -e .[tpu]

3. Install TPU specific packages for training:

pip install torch~=2.2.0 torch_xla[tpu]~=2.2.0 -f https://storage.googleapis.com/libtpu-releases/index.html

GPU Inference

For those looking to perform inference using GPUs, here’s how:

1. Clone the repository and navigate to the codebase:

bash git clone https://github.com/cambrian-mllm/cambrian
cd cambrian

2. Install the necessary packages:

shell
conda create -n cambrian python=3.10 -y
conda activate cambrian
pip install --upgrade pip  # enable PEP 660 support
pip install .[gpu]

Cambrian Weights

Cambrian provides model checkpoints that excel across various dimensions in visual token integration, particularly for models at the 8B, 13B, and 34B levels. These models demonstrate competitive performance against proprietary solutions on multiple benchmarks.

To download the model weights, you can access:

• Cambrian-1-8B
• Cambrian-1-13B
• Cambrian-1-34B

How to Use Cambrian-1

Imagine Cambrian-1 like a versatile toolbox for artists. Just as artists might use varying tools for different styles—brushes for painting, chisels for sculpting—Cambrian-1 offers various model sizes (8B, 13B, 34B), each tuned for different tasks. The ability to adjust the model size helps match the project requirements, whether you’re working on something simple or complex.

To use the model, simply load it in your preferred environment. Refer to the sample code provided in the inference.py file for guidance.

Troubleshooting

If you encounter problems during installation or model inference, here are some troubleshooting tips:

• Ensure that your GPU/TPU configurations are correct and up to date.
• Double-check the model paths you provide while loading the models.
• Verify that your dataset formats comply with expected JSONL standards for smooth loading.
