## Model |
|
llava-clip-internlm2-1_8b-pretrain-v1 is a LLaVA checkpoint finetuned from [internlm2-chat-1_8b](https://huggingface.co./internlm/internlm2-chat-1_8b) and [CLIP-ViT-Large-patch14-336](https://huggingface.co./openai/clip-vit-large-patch14-336) with [LLaVA-Pretrain](liuhaotian/LLaVA-Pretrain) by [Xtuner](https://github.com/InternLM/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] |
|
apt install git-lfs |
|
git clone https://huggingface.co./StarCycle/llava-clip-internlm2-1_8b-pretrain-v1 |
|
cd ./llava-clip-internlm2-1_8b-pretrain-v1 |
|
``` |
|
|
|
## 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 |
|
``` |
|
|
|
2. |
|
``` |
|
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. |
|
|
|
3. |
|
``` |
|
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 |
|
``` |
|
|
|
5. If your training process is killed during data preprocessing, you can modify the `map_num_proc` in xtuner/xtuner/dataset |
|
/huggingface.py |
|
``` |
|
def process(dataset, |
|
do_dataset_tokenization=True, |
|
tokenizer=None, |
|
max_length=None, |
|
dataset_map_fn=None, |
|
template_map_fn=None, |
|
max_dataset_length=None, |
|
split='train', |
|
remove_unused_columns=False, |
|
rename_maps=[], |
|
shuffle_before_pack=True, |
|
pack_to_max_length=True, |
|
use_varlen_attn=False, |
|
input_ids_with_output=True, |
|
with_image_token=False, |
|
map_num_proc=32): # modify it to a smaller number, e.g., 4 |
|
``` |
|
|
|
6. If you fail to load the model, check whether you installed git-lfs and actually downloaded the model file. |

## Cheers! Now train your own model! |
|
1. Alignment module pretraining |
|
``` |
|
# single GPU |
|
xtuner train ./llava_internlm2_chat_1_8b_clip_vit_large_p14_336_e1_gpu1_pretrain.py --deepspeed deepspeed_zero2 |
|
|
|
# multiple GPU |
|
NPROC_PER_NODE=8 xtuner train ./llava_internlm2_chat_1_8b_clip_vit_large_p14_336_e1_gpu1_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. |
