Model

llava-clip-internlm2-1_8b-pretrain-v1 is a LLaVA checkpoint finetuned from internlm2-chat-1_8b and CLIP-ViT-Large-patch14-336 with LLaVA-Pretrain by Xtuner. The pretraining phase took 16 hours on a single Nvidia A6000 ada GPU.

The total size of the model is around 2.2B, which is suitable for embedded applications like robotics.

I just finished the pretrain phase of the model. I will release the full finetuned model soon. You can also finetune your own version based on the checkpoint here.

Installation

git clone https://github.com/InternLM/xtuner
pip install -e ./xtuner[deepspeed]

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

4. To use tensorboard to visualize the training loss curve:

pip install future tensorboard

Cheers! Now train your own model!

1. 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.

This is my loss curve for llava-clip-internlm2-1_8b-pretrain-v1:
