🎉 Introduction

Welcome to Parrot [paper], a novel method that utilizes textual guidance to drive visual token alignment at the language level. Parrot makes the visual tokens condition on diverse language inputs and uses Mixture-of-Experts (MoE) to promote the alignment of multilingual tokens. Moreover, considering the current lack of benchmarks for evaluating multilingual capabilities within the field, we collect and make available a Massive Multilingual Multimodal Benchmark which includes 6 languages, 15 categories, and 12,000 questions, named as MMMB.

🦜 Model

Parrot is a multilingual multimodal large language model. We provide our fully finetuned models below:

Model	Base LLM	Vision Encoder	Stage	Download
Parrot-7B	Qwen-1.5-7B-Chat	CLIP-ViT-Large-patch14-336	SFT	ckpt
Parrot-14B	Qwen-1.5-14B-Chat	CLIP-ViT-Large-patch14-336	SFT	ckpt

🔥 Train

Parrot is trained in two stages: modality alignment and instruction tuning for multilingual alignment. Each stage's training script is provided in the scripts folder. Before starting the training, ensure you properly set the ROOT variable in the training script. Below are the commands to train Parrot for each stage:

bash scripts/train/pretrain.sh
bash scripts/train/finetune.sh

Hyperparameters

We use a similar set of hyperparameters as Vicuna in finetuning. Both hyperparameters used in pretraining and finetuning are provided below.

1. Pretraining

Model	Global Batch Size	Learning rate	Epochs	Max length	Weight decay
Parrot-7B	256	1e-3	1	2048	0

2. Finetuning

Model	Global Batch Size	Learning rate	Epochs	Max length	Weight decay
Parrot-7B	128	2e-5	1	2048	0

Our base model Qwen1.5-7B-Chat, which is an instruction-tuned chatbot, can be downloaded from here.

🔎 Datasets

All training datasets are summarized in the Python file located at parrot/train/utils/utils.py. Each dataset contains a collection of samples where each sample consists of text and (optionally) image. The text data is embedded directly within the JSON file, while the image is represented by its filename. This filename refers to the image file located in the image_dir.

We provide the JSON file for each training dataset at Huggingface. The images can be downloaded from their respective sources listed below.

dataset name	image dir	image source

🎄 MMMB

We provide the MMMB benchmark at Huggingface. It contains 6 languages, 15 categories, and 12,000 questions (Following the company's data review, it was identified that some of the data might contain non-compliant information, which could result in the total number of entries in the dataset being slightly fewer than 2,000.) You can download the dataset and use it for your own experiments. We utilize the tsv file to store the dataset, and it is easy to evaluate using the VLMEvalKit.

🔑 Evaluation

We use the VLMEvalKit to evaluate MLLMs.

To evaluate the multilingual capabilities of Parrot, we conduct a comprehensive comparison of it with the state-of-the-art approaches using multilingual benchmarks. Additionally, we compare Parrot with leading models across a range of multimodal tasks. To ensure the reproducibility, we evaluate the models using VLMEvalKit. You can find the evaluation script in VLMEvalKit/run.sh. Before running the script, please replace the paths related to the model and the dataset in the script.

📍 Quick Start

We provide a quick start demo in parrot/deploy/runner.py, which can be used as a template to run Parrot for inference.

1. Before running the demo, please make sure you download the Parrot checkpoint and the Clip checkpoint.
2. Second, you should replace the paths in the runner.py.
3. Finally, run the python file in your system.
