😮 Highlights

💡 High performance, but NO intermediate modality required

LanguageBind is a language-centric multimodal pretraining approach, taking the language as the bind across different modalities because the language modality is well-explored and contains rich semantics.

• The following first figure shows the architecture of LanguageBind. LanguageBind can be easily extended to segmentation, detection tasks, and potentially to unlimited modalities.

⚡️ A multimodal, fully aligned and voluminous dataset

We propose VIDAL-10M, 10 Million data with Video, Infrared, Depth, Audio and their corresponding Language, which greatly expands the data beyond visual modalities.

• The second figure shows our proposed VIDAL-10M dataset, which includes five modalities: video, infrared, depth, audio, and language.

🔥 Multi-view enhanced description for training

We make multi-view enhancements to language. We produce multi-view description that combines meta-data, spatial, and temporal to greatly enhance the semantic information of the language. In addition we further enhance the language with ChatGPT to create a good semantic space for each modality aligned language.

🤗 Demo

• Local demo. Highly recommend trying out our web demo, which incorporates all features currently supported by LanguageBind.

python gradio_app.py

• Online demo. We provide the online demo in Huggingface Spaces. In this demo, you can calculate the similarity of modalities to language, such as audio-to-language, video-to-language, and depth-to-image.

🛠️ Requirements and Installation

• Python >= 3.8
• Pytorch >= 1.13.1
• CUDA Version >= 11.6
• Install required packages:

git clone https://github.com/PKU-YuanGroup/LanguageBind
cd LanguageBind
pip install torch==1.13.1+cu116 torchvision==0.14.1+cu116 torchaudio==0.13.1 --extra-index-url https://download.pytorch.org/whl/cu116

🐳 Model Zoo

The names in the table represent different encoder models. For example, LanguageBind/LanguageBind_Video_FT represents the fully fine-tuned version, while LanguageBind/LanguageBind_Video represents the LoRA-tuned version.

You can freely replace them in the recommended API usage. We recommend using the fully fine-tuned version, as it offers stronger performance.

🤖 API

We open source all modalities preprocessing code. If you want to load the model (e.g. LanguageBind/LanguageBind_Thermal) from the model hub on Huggingface or on local, you can use the following code snippets!

Inference for Multi-modal Binding

We have provided some sample datasets in assets to quickly see how languagebind works.

import torch
from languagebind import LanguageBind, to_device, transform_dict, LanguageBindImageTokenizer

if __name__ == '__main__':
    device = 'cuda:0'
    device = torch.device(device)
    clip_type = {
        'video': 'LanguageBind_Video_FT',  # also LanguageBind_Video
        'audio': 'LanguageBind_Audio_FT',  # also LanguageBind_Audio
        'thermal': 'LanguageBind_Thermal',
        'image': 'LanguageBind_Image',
        'depth': 'LanguageBind_Depth',
    }

    model = LanguageBind(clip_type=clip_type, cache_dir='./cache_dir')
    model = model.to(device)
    model.eval()
    pretrained_ckpt = f'lb203/LanguageBind_Image'
    tokenizer = LanguageBindImageTokenizer.from_pretrained(pretrained_ckpt, cache_dir='./cache_dir/tokenizer_cache_dir')
    modality_transform = {c: transform_dict[c](model.modality_config[c]) for c in clip_type.keys()}

    image = ['assets/image/0.jpg', 'assets/image/1.jpg']
    audio = ['assets/audio/0.wav', 'assets/audio/1.wav']
    video = ['assets/video/0.mp4', 'assets/video/1.mp4']
    depth = ['assets/depth/0.png', 'assets/depth/1.png']
    thermal = ['assets/thermal/0.jpg', 'assets/thermal/1.jpg']
    language = ["Training a parakeet to climb up a ladder.", 'A lion climbing a tree to catch a monkey.']

    inputs = {
        'image': to_device(modality_transform['image'](image), device),
        'video': to_device(modality_transform['video'](video), device),
        'audio': to_device(modality_transform['audio'](audio), device),
        'depth': to_device(modality_transform['depth'](depth), device),
        'thermal': to_device(modality_transform['thermal'](thermal), device),
    }
    inputs['language'] = to_device(tokenizer(language, max_length=77, padding='max_length',
                                             truncation=True, return_tensors='pt'), device)

    with torch.no_grad():
        embeddings = model(inputs)

    print("Video x Text: \n",
          torch.softmax(embeddings['video'] @ embeddings['language'].T, dim=-1).detach().cpu().numpy())
    print("Image x Text: \n",
          torch.softmax(embeddings['image'] @ embeddings['language'].T, dim=-1).detach().cpu().numpy())
    print("Depth x Text: \n",
          torch.softmax(embeddings['depth'] @ embeddings['language'].T, dim=-1).detach().cpu().numpy())
    print("Audio x Text: \n",
          torch.softmax(embeddings['audio'] @ embeddings['language'].T, dim=-1).detach().cpu().numpy())
    print("Thermal x Text: \n",
          torch.softmax(embeddings['thermal'] @ embeddings['language'].T, dim=-1).detach().cpu().numpy())

Then returns the following result.

Video x Text: 
 [[9.9989331e-01 1.0667283e-04]
 [1.3255903e-03 9.9867439e-01]]
Image x Text: 
 [[9.9990666e-01 9.3292067e-05]
 [4.6132666e-08 1.0000000e+00]]
Depth x Text: 
 [[0.9954276  0.00457235]
 [0.12042473 0.8795753 ]]
Audio x Text: 
 [[0.97634876 0.02365119]
 [0.02917843 0.97082156]]
Thermal x Text: 
 [[0.9482511  0.0517489 ]
 [0.48746133 0.5125386 ]]

Emergency zero-shot

Since languagebind binds each modality together, we also found the emergency zero-shot. It's very simple to use.

print("Video x Audio: \n", torch.softmax(embeddings['video'] @ embeddings['audio'].T, dim=-1).detach().cpu().numpy())
print("Image x Depth: \n", torch.softmax(embeddings['image'] @ embeddings['depth'].T, dim=-1).detach().cpu().numpy())
print("Image x Thermal: \n", torch.softmax(embeddings['image'] @ embeddings['thermal'].T, dim=-1).detach().cpu().numpy())

Then, you will get:

Video x Audio: 
 [[1.0000000e+00 0.0000000e+00]
 [3.1150486e-32 1.0000000e+00]]
Image x Depth: 
 [[1. 0.]
 [0. 1.]]
Image x Thermal: 
 [[1. 0.]
 [0. 1.]]

Different branches for X-Language task

Additionally, LanguageBind can be disassembled into different branches to handle different tasks. Note that we do not train Image, which just initialize from OpenCLIP.

Thermal

import torch
from languagebind import LanguageBindThermal, LanguageBindThermalTokenizer, LanguageBindThermalProcessor

pretrained_ckpt = 'LanguageBind/LanguageBind_Thermal'
model = LanguageBindThermal.from_pretrained(pretrained_ckpt, cache_dir='./cache_dir')
tokenizer = LanguageBindThermalTokenizer.from_pretrained(pretrained_ckpt, cache_dir='./cache_dir')
thermal_process = LanguageBindThermalProcessor(model.config, tokenizer)

model.eval()
data = thermal_process([r"your/thermal.jpg"], ['your text'], return_tensors='pt')
with torch.no_grad():
    out = model(**data)

print(out.text_embeds @ out.image_embeds.T)

Depth

import torch
from languagebind import LanguageBindDepth, LanguageBindDepthTokenizer, LanguageBindDepthProcessor

pretrained_ckpt = 'LanguageBind/LanguageBind_Depth'
model = LanguageBindDepth.from_pretrained(pretrained_ckpt, cache_dir='./cache_dir')
tokenizer = LanguageBindDepthTokenizer.from_pretrained(pretrained_ckpt, cache_dir='./cache_dir')
depth_process = LanguageBindDepthProcessor(model.config, tokenizer)

model.eval()
data = depth_process([r"your/depth.png"], ['your text.'], return_tensors='pt')
with torch.no_grad():
    out = model(**data)

print(out.text_embeds @ out.image_embeds.T)

Video

import torch
from languagebind import LanguageBindVideo, LanguageBindVideoTokenizer, LanguageBindVideoProcessor

pretrained_ckpt = 'LanguageBind/LanguageBind_Video_FT'  # also 'LanguageBind/LanguageBind_Video'
model = LanguageBindVideo.from_pretrained(pretrained_ckpt, cache_dir='./cache_dir')
tokenizer = LanguageBindVideoTokenizer.from_pretrained(pretrained_ckpt, cache_dir='./cache_dir')
video_process = LanguageBindVideoProcessor(model.config, tokenizer)

model.eval()
data = video_process(["your/video.mp4"], ['your text.'], return_tensors='pt')
with torch.no_grad():
    out = model(**data)

print(out.text_embeds @ out.image_embeds.T)

Audio

import torch
from languagebind import LanguageBindAudio, LanguageBindAudioTokenizer, LanguageBindAudioProcessor

pretrained_ckpt = 'LanguageBind/LanguageBind_Audio_FT'  # also 'LanguageBind/LanguageBind_Audio'
model = LanguageBindAudio.from_pretrained(pretrained_ckpt, cache_dir='./cache_dir')
tokenizer = LanguageBindAudioTokenizer.from_pretrained(pretrained_ckpt, cache_dir='./cache_dir')
audio_process = LanguageBindAudioProcessor(model.config, tokenizer)

model.eval()
data = audio_process([r"your/audio.wav"], ['your audio.'], return_tensors='pt')
with torch.no_grad():
    out = model(**data)

print(out.text_embeds @ out.image_embeds.T)

Image

Note that our image encoder is the same as OpenCLIP. Not as fine-tuned as other modalities.

import torch
from languagebind import LanguageBindImage,  LanguageBindImageTokenizer,  LanguageBindImageProcessor

pretrained_ckpt = 'LanguageBind/LanguageBind_Image'
model = LanguageBindImage.from_pretrained(pretrained_ckpt, cache_dir='./cache_dir')
tokenizer = LanguageBindImageTokenizer.from_pretrained(pretrained_ckpt, cache_dir='./cache_dir')
image_process = LanguageBindImageProcessor(model.config, tokenizer)

model.eval()
data = image_process([r"your/image.jpg"], ['your text.'], return_tensors='pt')
with torch.no_grad():
    out = model(**data)

print(out.text_embeds @ out.image_embeds.T)
