Supported Features

• Training on the mixture of NLP data and vision-language data
• Flexible selection of LoRA target modules
• Deepspeed Zero-2
• Deepspeed Zero-3
• PyTorch FSDP
• Gradient checkpointing (only compatible with ZeRO-3 for now)
• QLoRA
• Disable/enable Flash Attention 2

Installation

Install the required packages using either requirements.txt or environment.yml.

Using requirements.txt

pip install -r requirements.txt

Using environment.yml

conda env create -f environment.yml
conda activate phi3v

Model Download

Before training, download the Phi3-V model from HuggingFace. It is recommended to use the huggingface-cli to do this.

1. Install the HuggingFace CLI:

pip install -U "huggingface_hub[cli]"

2. Download the model:

huggingface-cli download microsoft/Phi-3-vision-128k-instruct --local-dir Phi-3-vision-128k-instruct --resume-download

Usage

To run the training script, use the following command:

bash scripts/train.sh

Note: Remember to replace the paths in train.sh with your specific paths.

Arguments

• --data_path (str): Path to the LLaVA formatted training data (a JSON file). (Required)
• --image_folder (str): Path to the images folder as referenced in the LLaVA formatted training data. (Required)
• --model_id (str): Path to the Phi3-V model. (Required)
• --proxy (str): Proxy settings (default: None).
• --output_dir (str): Output directory for model checkpoints (default: "output/test_train").
• --num_train_epochs (int): Number of training epochs (default: 1).
• --per_device_train_batch_size (int): Training batch size per GPU per forwarding step.
• --gradient_accumulation_steps (int): Gradient accumulation steps (default: 4).
• --deepspeed_config (str): Path to DeepSpeed config file (default: "scripts/zero2.json").
• --num_lora_modules (int): Number of target modules to add LoRA (-1 means all layers).
• --lora_namespan_exclude (str): Exclude modules with namespans to add LoRA.
• --max_seq_length (int): Maximum sequence length (default: 3072).
• --quantization (flag): Enable quantization.
• --disable_flash_attn2 (flag): Disable Flash Attention 2.
• --report_to (str): Reporting tool (choices: 'tensorboard', 'wandb', 'none') (default: 'tensorboard').
• --logging_dir (str): Logging directory (default: "./tf-logs").
• --lora_rank (int): LoRA rank (default: 128).
• --lora_alpha (int): LoRA alpha (default: 256).
• --lora_dropout (float): LoRA dropout (default: 0.05).
• --logging_steps (int): Logging steps (default: 1).
• --dataloader_num_workers (int): Number of data loader workers (default: 4).

Dataset Preparation

The script requires a dataset formatted according to the LLaVA specification. The dataset should be a JSON file where each entry contains information about conversations and images. Ensure that the image paths in the dataset match the provided --image_folder.

[
  {
    "id": "000000033471",
    "image": "000000033471.jpg",
    "conversations": [
      {
        "from": "human",
        "value": "<image>\nWhat are the colors of the bus in the image?"
      },
      {
        "from": "gpt",
        "value": "The bus in the image is white and red."
      },
      {
        "from": "human",
        "value": "What feature can be seen on the back of the bus?"
      },
      {
        "from": "gpt",
        "value": "The back of the bus features an advertisement."
      },
      {
        "from": "human",
        "value": "Is the bus driving down the street or pulled off to the side?"
      },
      {
        "from": "gpt",
        "value": "The bus is driving down the street, which is crowded with people and other vehicles."
      }
    ]
  }
  ...
]
