InternLM-XComposer2-4KHD is a general vision-language large model (VLLM) based on InternLM2, with the capability of 4K resolution image understanding.
Import from Transformers
To load the InternLM-XComposer2-4KHD model using Transformers, use the following code:
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
ckpt_path = "internlm/internlm-xcomposer2-4khd-7b"
tokenizer = AutoTokenizer.from_pretrained(ckpt_path, trust_remote_code=True).cuda()
# Set `torch_dtype=torch.floatb16` to load model in bfloat16, otherwise it will be loaded as float32 and might cause OOM Error.
model = AutoModelForCausalLM.from_pretrained(ckpt_path, torch_dtype=torch.bfloat16, 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-xcomposer2-4khd-7b', torch_dtype=torch.bfloat16, trust_remote_code=True).cuda().eval()
tokenizer = AutoTokenizer.from_pretrained('internlm/internlm-xcomposer2-4khd-7b', trust_remote_code=True)

# The image is a vibrant and colorful infographic that showcases 7 graphic design trends that will dominate in 2021. The infographic is divided into 7 sections, each representing a different trend.
# Starting from the top, the first section focuses on "Muted Color Palettes", highlighting the use of muted colors in design.
# The second section delves into "Simple Data Visualizations", emphasizing the importance of easy-to-understand data visualizations.
# The third section introduces "Geometric Shapes Everywhere", showcasing the use of geometric shapes in design.
# The fourth section discusses "Flat Icons and Illustrations", explaining how flat icons and illustrations are being used in design.
# The fifth section is dedicated to "Classic Serif Fonts", illustrating the resurgence of classic serif fonts in design.
# The sixth section explores "Social Media Slide Decks", illustrating how slide decks are being used on social media.
# Finally, the seventh section focuses on "Text Heavy Videos", illustrating the trend of using text-heavy videos in design.
# Each section is filled with relevant images and text, providing a comprehensive overview of the 7 graphic design trends that will dominate in 2021.

# The third part of the infographic is about "Geometric Shapes Everywhere". It explains that last year, designers used a lot of
# flowing and abstract shapes in their designs. However, this year, they have been replaced with rigid, hard-edged geometric
# shapes and patterns. The hard edges of a geometric shape create a great contrast against muted colors.
