-## Install Prerequisites
+## Install denpendencies
 
 - install PyTorch >=0.3 with GPU (code are gpu-only), refer to [official website](http://pytorch.org)
 - install cupy, you can install via `pip install` but it's better to read the [docs](https://docs-cupy.chainer.org/en/latest/install.html#install-cupy-with-cudnn-and-nccl) and make sure the environ is correctly set
 
 
 - install other dependencies:  `pip install -r requirements.txt `
-- Optional but recommended： build `nms_gpu_post`: `cd model/utils/nmspython3 build.py build_ext --inplace`
+- build `nms_gpu_post`: `cd model/utils/nms/; python3 build.py build_ext --inplace`
