本文详细介绍了在Ubuntu操作系统下如何配置PyTorch环境。从安装CUDA、cuDNN等依赖库开始，逐步讲解了PyTorch的安装过程，包括CPU和GPU版本的区分，以及如何解决配置过程中可能遇到的问题，为开发者提供了清晰的Ubuntu PyTorch环境搭建指南。
本文目录导读：
在深度学习领域，PyTorch是一个非常受欢迎的框架，它以其灵活性和易用性著称，对于许多开发者而言，在Ubuntu操作系统上配置PyTorch环境是进行深度学习项目的前提，本文将详细介绍如何在Ubuntu上安装和配置PyTorch环境，帮助读者快速上手。
系统要求
在进行PyTorch环境配置之前，首先确保你的Ubuntu操作系统版本为18.04或更高版本，这是因为较低版本的Ubuntu可能不支持PyTorch的最新特性。
安装CUDA
PyTorch支持CPU和GPU两种模式，如果你打算使用GPU加速，就需要安装CUDA，以下是在Ubuntu上安装CUDA的步骤：
1、访问NVIDIA官方网站下载CUDA Toolkit，选择合适的版本，通常选择最新版本。
2、解压下载的CUDA Toolkit压缩包。
3、打开终端，切换到CUDA Toolkit的解压目录，运行以下命令安装CUDA：
sudo ./cuda_XX.XX.XX_YYYY-YY-YY_linux.run
XX.XX.XX是CUDA版本号，YYYY-YY-YY是发布日期。
4、安装完成后，编辑~/.bashrc文件，添加以下环境变量：
export PATH=/usr/local/cuda-10.0/bin${PATH:+:}
export LD_LIBRARY=/usr/local/cuda-10.0/lib${LD_LIBRARY:=/usr/local/cuda-10.0/lib${LD_LIBRARY:=/usr/local/cuda-10.1/lib${LD_LIBRARY:=/usr/local/cuda-11.1/lib}安装PyTorch
PyTorch的安装可以通过多种方式，以下是几种常见的安装方式：
1. 使用pip安装
若要使用pip安装PyTorch，首先确保已安装了pip和wheel，以下为安装PyTorch的命令：
