Monkey-Chat

conda create -n monkey python=3.9
conda activate monkey
git clone https://github.com/Yuliang-Liu/Monkey.git
cd ./Monkey
pip install -r requirements.txt

You can download the corresponding version of flash_attention from https://github.com/Dao-AILab/flash-attention/releases/ and use the following code to install:

pip install flash_attn-2.3.5+cu117torch2.0cxx11abiFALSE-cp39-cp39-linux_x86_64.whl --no-build-isolation

We also offer Monkey's model definition and training code, which you can explore above. You can execute the training code through executing finetune_ds_debug.sh, finetune_textmonkey.sh.

The json file used for Monkey training can be downloaded at Link.

ATTENTION: Specify the path to your training data, which should be a json file consisting of a list of conversations.

Inspired by Qwen-VL, we freeze the Large Language Model (LLM) and introduce LoRA into four linear layers "c_attn", "attn.c_proj", "w1", "w2" for training. This step makes it possible to train Monkey using 8 NVIDIA 3090 GPUs. The specific implementation code is in modeling_qwen_nvdia3090.py.

• Add LoRA: You need to replace the contents of modeling_qwen.py with the contents of modeling_qwen_nvdia3090.py.
• Freeze LLM: You need to freeze other modules except LoRA and Resampler modules in finetune_multitask.py.

Run the inference code for Monkey and Monkey-Chat:

python ./inference.py --model_path MODEL_PATH  --image_path IMAGE_PATH  --question "YOUR_QUESTION"

Demo is fast and easy to use. Simply uploading an image from your desktop or phone, or capture one directly. Demo_chat is also launched as an upgraded version of the original demo to deliver an enhanced interactive experience.

We also provide the source code and the model weight for the original demo, allowing you to customize certain parameters for a more unique experience. The specific operations are as follows:

1. Make sure you have configured the environment.
2. You can choose to use the demo offline or online:

• Offline:
  • Download the Model Weight.
  • Modify DEFAULT_CKPT_PATH="pathto/Monkey" in the demo.py file to your model weight path.
  • Run the demo using the following command:

   python demo.py
  

• Online:
  • Run the demo and download model weights online with the following command:

   python demo.py -c echo840/Monkey 
  

For TextMonkey you can download the model weight from Model Weight and run the demo code:

python demo_textmonkey.py -c model_path

Before 14/11/2023, we have observed that for some random pictures Monkey can achieve more accurate results than GPT4V.

Before 31/1/2024, Monkey-chat achieved the fifth rank in the Multimodal Model category on OpenCompass.

The json file used for Monkey training can be downloaded at Link.

The data from our multi-level description generation method is now open-sourced and available for download at Link. Examples:

You can download train images of Monkey from Train. Extraction code: 4hdh

You can download test images and jsonls of Monkey from Test. Extraction code: 5h71

The images are from CC3M, COCO Caption, TextCaps, VQAV2, OKVQA, GQA, ScienceQA, VizWiz, TextVQA, OCRVQA, ESTVQA, STVQA, AI2D and DUE_Benchmark. When using the data, it is necessary to comply with the protocols of the original dataset.

We offer evaluation code for 14 Visual Question Answering (VQA) datasets in the evaluate_vqa.py file, facilitating a quick verification of results. The specific operations are as follows:

1. Make sure you have configured the environment.
2. Modify sys.path.append("pathto/Monkey") to the project path.
3. Prepare the datasets required for evaluation.
4. Run the evaluation code.

Take ESTVQA as an example:

• Prepare data according to the following directory structure:

├── data
|	├── estvqa
|		├── test_image
|			├── {image_path0}
|			├── {image_path1}
|				  ·
|				  ·
|	├── estvqa.jsonl

• Example of the format of each line of the annotated .jsonl file:

{"image": "data/estvqa/test_image/011364.jpg", "question": "What is this store?", "answer": "pizzeria", "question_id": 0}

• Modify the dictionary ds_collections:

ds_collections = {
	'estvqa_test': {
		'test': 'data/estvqa/estvqa.jsonl',
		'metric': 'anls',
		'max_new_tokens': 100,
	},
	...
}

• Run the following command:

bash eval/eval.sh 'EVAL_PTH' 'SAVE_NAME'
