InternLM-XComposer2
is a vision-language large model (VLLM) based on
InternLM2
for advanced text-image comprehension and composition.
We release InternLM-XComposer2 series in two versions:
InternLM-XComposer2-VL: The pretrained VLLM model with InternLM2 as the initialization of the LLM, achieving strong performance on various multimodal benchmarks.
InternLM-XComposer2: The finetuned VLLM for
Free-from Interleaved Text-Image Composition
.
Import from Transformers
To load the InternLM-XComposer2-VL-1.8B model using Transformers, use the following code:
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
ckpt_path = "internlm/internlm-xcomposer2-vl-1_8b"
tokenizer = AutoTokenizer.from_pretrained(ckpt_path, trust_remote_code=True).cuda()
# Set `torch_dtype=torch.float16` to load model in float16, otherwise it will be loaded as float32 and might cause OOM Error.
model = AutoModelForCausalLM.from_pretrained(ckpt_path, torch_dtype=torch.float16, trust_remote_code=True).cuda()
model = model.eval()
Quickstart
We provide a simple example to show how to use InternLM-XComposer with 🤗 Transformers.
import torch
from transformers import AutoModel, AutoTokenizer
torch.set_grad_enabled(False)
# init model and tokenizer
model = AutoModel.from_pretrained('internlm/internlm-xcomposer2-vl-1_8b', trust_remote_code=True).cuda().eval()
tokenizer = AutoTokenizer.from_pretrained('internlm/internlm-xcomposer2-vl-1_8b', trust_remote_code=True)
query = '<ImageHere>Please describe this image in detail.'
image = './image1.webp'with torch.cuda.amp.autocast():
response, _ = model.chat(tokenizer, query=query, image=image, history=[], do_sample=False)
print(response)
# The image is a captivating photograph of a sunset over a mountainous landscape. The sky, painted in hues of orange and pink,# serves as a backdrop for two silhouetted figures standing on the mountain. The text on the image, written in white, is a quote # from Oscar Wilde, which reads, "Live life with no excuses, travel with no regret." This quote, combined with the serene setting,# serves as a powerful reminder to embrace life's journey without hesitation or regret.
