Model
llava-dinov2-internlm2-7b-v1 is a LLaVA model fine-tuned from InternLM2-Chat-7B and Dinov2-large with LLaVA-Pretrain and LLaVA-Instruct by XTuner. I thank the help of Zhihao Lin and pppppM from the Xtuner team. I also thank the Huggingface transformers team for approving my pull request so training Dinov2 in bf16 becomes possible.
I did not carefully tune the training hyperparameters but the model still show capability to solve some tasks. It shows that a visual encoder can be integrated with an LLM, even when the encoder is not aligned with natural language with contrastive learning like CLIP.

Quickstart
Installation
git clone https://github.com/InternLM/xtuner
pip install -e ./xtuner[deepspeed]
cd ./xtuner
# Now replace the source code files with the modifed version in modified_xtuner_code directory

Common Errors
1.
command error: 'libGL.so.1: cannot open shared object file: No such file or directory'!
You can solve it by
# For Ubuntu
sudo apt-get update
sudo apt-get install libgl1-mesa-glx
# For CentOS and Fedora
sudo yum install mesa-libGL
Error: mkl-service + Intel(R) MKL: MKL_THREADING_LAYER=INTEL is incompatible with libgomp.so.1 library.
Try to import numpy first or set the threading layer accordingly. Set MKL_SERVICE_FORCE_INTEL to force it.
You can solve it by reinstall numpy.
ImportError:
InternLM2Converter requires the protobuf library but it was not found in your environment. Checkout the instructions on the
You just need
pip install protobuf
Training
- Alignment module pretraining
NPROC_PER_NODE=8 xtuner train ./llava_internlm2_chat_7b_dinov2_e1_gpu8_pretrain.py --deepspeed deepspeed_zero2
The checkpoint and tensorboard logs are saved by default in ./work_dirs/. I only train it for 1 epoch to be same as the original LLaVA paper. Some researches also report that training for multiple epochs will make the model overfit the training dataset and perform worse in other domains.
Here is my loss curve:
- Instruction following fine-tuning
NPROC_PER_NODE=8 xtuner train ./llava_internlm2_chat_7b_dinov2_e1_gpu8_finetune.py --deepspeed deepspeed_zero2
Here is my loss curve (the curve fluctuates strongly because the batch size is small, and I only record batch loss instead of epoch loss):
Transfer the checkpoints to Huggingface safetensor format
xtuner convert pth_to_hf ./llava_internlm2_chat_7b_dinov2_e1_gpu8_finetune.py ./work_dirs/epoch_1.pth ./my_lora_and_projector
The adapter still need to be used with the internlm/internlm2-chat-7b and facebook/dinov2-large models. I have not tried to merge them yet but it is possible with Xtuner, see this tutorial.
MMBench Evaluation

Deployment
Xtuner team is developing HF chatbot (based on Huggingface transformers) and LMDeploy chatbot (based on TurboMind). I am waiting for their final version of API.
