Caffe

The current repository is forked from BVLC/caffe and updated to accommodate Python 3, OpenCV 4, CUDA 11.X and cuDNN 8.

Use Caffe with Docker

It is recommended to pull the Docker image duruyao/caffe with the updated Caffe built-in instead of the Docker image bvlc/caffe.

docker pull duruyao/caffe:cpu
docker pull duruyao/caffe:gpu

The following table lists some major differences between my own Docker image and the official Docker image.

bvlc/caffe	duruyao/caffe
ubuntu 16.04	ubuntu 22.04
cuda 8.0	cuda 11.8.0
cudnn 6	cudnn 8
python 2	python 3
opencv 3	opencv 4
