+
+## Build Through Dockerfile
+Build docker image that support OpenPCDet through:
+```shell script
+docker build ./ -t openpcdet-docker

+Note that if you would like to use dynamic voxelization, you need further install [`torch_scatter`](https://github.com/rusty1s/pytorch_scatter) package. 
+
+From this Dockerfile, the installed version of spconv is 2.x, if you would like to use spconv 1.2.1, please follow these steps:
+```shell script
+git clone -b v1.2.1 https://github.com/djiajunustc/spconv spconv --recursive
+cd spconv
+python setup.py bdist_wheel
+cd ./dist
+pip install *.whl
+```
