DeepSeek-VL: A Python repository from cduk

1. Introduction

Introducing DeepSeek-VL, an open-source Vision-Language (VL) Model designed for real-world vision and language understanding applications. DeepSeek-VL possesses general multimodal understanding capabilities, capable of processing logical diagrams, web pages, formula recognition, scientific literature, natural images, and embodied intelligence in complex scenarios.

4. Quick Start

Installation

On the basis of Python >= 3.8 environment, install the necessary dependencies by running the following command:

pip install -e .

Simple Inference Example

import torch
from transformers import AutoModelForCausalLM

from deepseek_vl.models import VLChatProcessor, MultiModalityCausalLM
from deepseek_vl.utils.io import load_pil_images


# specify the path to the model
model_path = "deepseek-ai/deepseek-vl-7b-chat"
vl_chat_processor: VLChatProcessor = VLChatProcessor.from_pretrained(model_path)
tokenizer = vl_chat_processor.tokenizer

vl_gpt: MultiModalityCausalLM = AutoModelForCausalLM.from_pretrained(model_path, trust_remote_code=True)
vl_gpt = vl_gpt.to(torch.bfloat16).cuda().eval()

## single image conversation example
conversation = [
    {
        "role": "User",
        "content": "<image_placeholder>Describe each stage of this image.",
        "images": ["./images/training_pipelines.jpg"],
    },
    {"role": "Assistant", "content": ""},
]

## multiple images (or in-context learning) conversation example
# conversation = [
#     {
#         "role": "User",
#         "content": "<image_placeholder>A dog wearing nothing in the foreground, "
#                    "<image_placeholder>a dog wearing a santa hat, "
#                    "<image_placeholder>a dog wearing a wizard outfit, and "
#                    "<image_placeholder>what's the dog wearing?",
#         "images": [
#             "images/dog_a.png",
#             "images/dog_b.png",
#             "images/dog_c.png",
#             "images/dog_d.png",
#         ],
#     },
#     {"role": "Assistant", "content": ""}
# ]

# load images and prepare for inputs
pil_images = load_pil_images(conversation)
prepare_inputs = vl_chat_processor(
    conversations=conversation,
    images=pil_images,
    force_batchify=True
).to(vl_gpt.device)

# run image encoder to get the image embeddings
inputs_embeds = vl_gpt.prepare_inputs_embeds(**prepare_inputs)

# run the model to get the response
outputs = vl_gpt.language_model.generate(
    inputs_embeds=inputs_embeds,
    attention_mask=prepare_inputs.attention_mask,
    pad_token_id=tokenizer.eos_token_id,
    bos_token_id=tokenizer.bos_token_id,
    eos_token_id=tokenizer.eos_token_id,
    max_new_tokens=512,
    do_sample=False,
    use_cache=True
)

answer = tokenizer.decode(outputs[0].cpu().tolist(), skip_special_tokens=True)
print(f"{prepare_inputs['sft_format'][0]}", answer)

CLI Chat

python cli_chat.py --model_path "deepseek-ai/deepseek-vl-7b-chat"

# or local path
python cli_chat.py --model_path "local model path"
