Model
llava-siglip-internlm2-1_8b-pretrain-v1 is a LLaVA checkpoint finetuned from internlm2-chat-1_8b and siglip-so400m-patch14-384 with LLaVA-Pretrain and LLaVA-Instruct-150K by Xtuner. The pretraining phase took 5.5 hours on 4 Nvidia GTX 4090 GPU (see this intermediate checkpoint). The finetuning phase took 16 hours on 4 Nvidia GTX 4090 GPU.
The total size of the model is around 2.2B, which is suitable for embedded applications like robotics. This model performs slightly better than llava-clip-internlm2-1_8b-v1.
By the way, it's also stronger than MiniCPM-V (3B) in the test split on MMBench, with vert basic datasets and network design. Our model size is also smaller.
I have not carefully tune the hyperparameters during training. If you have any idea to improve it, please open an issue or just send an email to [email protected]. You are welcomed!

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.

- Alignment module pretraining
# single GPU
xtuner train ./pretrain.py --deepspeed deepspeed_zero2
# multiple GPU
NPROC_PER_NODE=4 xtuner train ./pretrain.py --deepspeed deepspeed_zero2
Remember to change the batch size and gradient accumulation parameters to fit your hardware. So your GPU_num * batch_size * gradient_accumulation is roughly equal to mine to reproduce the result.
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.
This is my loss curve for llava-siglip-internlm2-1_8b-pretrain-v1:
- Instruction following fine-tuning
NPROC_PER_NODE=4 xtuner train ./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 ./finetune.py ./work_dirs/iter_xxx.pth ./my_lora_and_projector
The adapter still need to be used with the internlm/internlm2-chat-1_8b and the vision encoder. I have not tried to merge them yet but it is possible with Xtuner, see this tutorial.
MMBench Evaluation
You can first download the MMBench data:
wget https://opencompass.openxlab.space/utils/VLMEval/MMBench_DEV_EN.tsv
wget https://opencompass.openxlab.space/utils/VLMEval/MMBench_TEST_EN.tsv
wget https://opencompass.openxlab.space/utils/VLMEval/MMBench_DEV_CN.tsv
wget https://opencompass.openxlab.space/utils/VLMEval/MMBench_TEST_CN.tsv
wget https://opencompass.openxlab.space/utils/VLMEval/CCBench.tsv
Then run:
NPROC_PER_NODE=8 xtuner mmbench internlm/internlm2-chat-1_8b \
--visual-encoder google/siglip-so400m-patch14-384 \
--llava ./my_lora_and_projector \
--prompt-template internlm2_chat \
--data-path $MMBENCH_DATA_PATH \
--work-dir $RESULT_PATH
You can also use VLMEvalKit to evaluate it on other benckmarks.
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.
