This repository contains our customized mmcv/mmsegmentation/mmdetection code, integrated with DeepSpeed, which can be used for training large-scale object detection and semantic segmentation models.

Note, this codebase requires you to install a lower version of the environment (i.e., torch==1.12.0), which is different from our main repository's environment.

[Paper] [Chat Demo] [Quick Start]

InternVL scales up the ViT to 6B parameters and aligns it with LLM.

It is the largest open-source vision/vision-language foundation model (14B) to date, achieving 32 state-of-the-art performances on a wide range of tasks such as visual perception, cross-modal retrieval, multimodal dialogue, etc.

• Semantic Segmentation [see details]

  method	decoder	#param (train/total)	crop size	mIoU

• Clone this repo:

  git clone https://github.com/OpenGVLab/InternVL-MMDetSeg
  cd InternVL-MMDetSeg/

• Create a conda virtual environment and activate it:

  conda create -n internvl-mmdetseg python=3.9 -y
  conda activate internvl-mmdetseg

• Install PyTorch>=1.11<2.0 and torchvision>=0.13.0 with CUDA>=10.2:

  For example, to install torch==1.12.0 with CUDA==11.3:

  conda install pytorch==1.12.0 torchvision==0.13.0 torchaudio==0.12.0 cudatoolkit=11.3 -c pytorch
  # or
  pip install torch==1.12.0+cu113 torchvision==0.13.0+cu113 torchaudio==0.12.0 --extra-index-url https://download.pytorch.org/whl/cu113

• Install flash-attn==0.2.8 :

  If you want to fully replicate my results, please install v0.2.8, otherwise install the latest version.

  This is because different versions of flash attention yield slight differences in results.

  git clone https://github.com/Dao-AILab/flash-attention.git
  cd flash-attention
  git checkout v0.2.8
  pip install ninja
  python setup.py install # I use gcc-7.3 to compile this package

• Install other requirements:

  conda install -c conda-forge termcolor yacs pyyaml scipy pip -y
  pip install opencv-python
  pip install timm==0.6.11
  pip install yapf==0.40.1
  pip install addict
  pip install deepspeed==0.8.0 # please install this old version
  pip install pydantic==1.10.2 # later versions may have compatibility issues

• Install tensorboard:

  pip install future tensorboard

• Install our customized mmcv-full==1.7.0:

  cd mmcv/
  export MMCV_WITH_OPS=1
  python setup.py develop
  cd ../

• Install our customized mmsegmentation & mmdetection:

  cd mmsegmentation/
  python setup.py develop
  cd ../
  cd mmdetection/
  python setup.py develop
  cd ../

• Compile the deformable attention (optional):

  # if you want to use ViT-Adapter, please compile the deformable attention operator
  cd ops
  sh compile.sh
  # Soft link the `ops` folder to the mmsegmentation directory
  cd ../mmsegmentation/
  ln -s ../ops ./

The usage is basically consistent with that of common mmsegmentation and mmdetection.

Please enter the corresponding folder to check README.
