01 环境搭建

《PyTorch基础教程》01 搭建环境 基于Docker搭建ubuntu22+Python3.10+Pytorch2+cuda11+jupyter的开发环境

Docker部署PyTorch

拉取cnstark/pytorch镜像

拉取镜像：

docker pull cnstark/pytorch:2.0.1-py3.10.11-cuda11.8.0-ubuntu22.04

导出镜像：

docker save -o pytorch2_python310_cuda11_ubuntu22.tar cnstark/pytorch:2.0.1-py3.10.11-cuda11.8.0-ubuntu22.04

导入镜像：

docker load -i pytorch2_python310_ubuntu22.tar

运行镜像：

mkdir -p /docker/pytorch/project
mkdir -p /docker/pytorch/dataset
docker run --name pytorch -itd -v /docker/pytorch/project:/workspace -v /docker/pytorch/dataset:/workspace/dataset cnstark/pytorch:2.0.1-py3.10.11-cuda11.8.0-ubuntu22.04# 开启GPU
docker run --name pytorch --gpus all -itd -v /docker/pytorch/project:/workspace -v /docker/pytorch/dataset:/workspace/dataset cnstark/pytorch:2.0.1-py3.10.11-cuda11.8.0-ubuntu22.04
