INSTAllation

Requirements

  • Linux (Recommend), Windows (not Recommend, Please refer to this issue if you have difficulty in generating utils/nms_rotated_ext.cpython-XX-XX-XX-XX.so)
  • Python 3.7+
  • PyTorch ≥ 1.11
  • CUDA 11.3 or higher

I have tested the following versions of OS and softwares：

  • OS：Ubuntu 20.04
  • CUDA: 11.3/11.6

Install

CUDA Driver Version ≥ CUDA Toolkit Version(runtime version) = torch.version.cuda

a. Create a conda virtual environment and activate it, e.g.,

conda create -n Py39_Torch1.11_cu11.3 python=3.9 -y 
source activate Py39_Torch1.11_cu11.3

b. Make sure your CUDA runtime api version ≤ CUDA driver version. (for example 11.3 ≤ 11.4)

nvcc -V
nvidia-smi

c. Install PyTorch and torchvision following the official instructions, Make sure cudatoolkit version same as CUDA runtime api version, e.g.,

pip3 install --no-cache torch==1.12.1+cu116 torchvision==0.13.1+cu116 torchaudio==0.12.1+cu116 --extra-index-url https://download.pytorch.org/whl/cu116
nvcc -V
python
>>> import torch
>>> torch.version.cuda
>>> exit()

d. Clone the yolov5-obb repository.

git clone https://github.com/ohashi/yolov5_obb.git
cd yolov5_obb

e. Install yolov5-obb.

pip install -r requirements.txt
cd utils/nms_rotated
python setup.py develop  #or "pip install -v -e ."

Install DOTA_devkit.

(Custom Install, it's just a tool to split the high resolution image and evaluation the obb)

cd yolov5_obb/DOTA_devkit
sudo apt-get install swig
swig -c++ -python polyiou.i
python setup.py build_ext --inplace
