环境搭建

个人记录文档，电脑系统为win11

1. 安装conda和pycharm，cuda，cuDNN以及pytorch
   conda和pychram安装不再赘述
   cuDNN:
   >复制解压后的cdDNN文件到cuda的相关安装目录即可，之后查看是否安装成功cuDNN
   conda建立好环境之后安装pytorch

conda create -n pytorch_gpu python=3.9 # 利用conda创建环境
# conda create --clone foo_env --name bar_env # 将foo_env的环境复制到新环境bar_env中
# 此时需查看自己电脑安装的cuda版本（2中有示例）
pip install torch==1.10.1+cu102 torchvision==0.11.2+cu102 torchaudio==0.10.1 -f https://download.pytorch.org/whl/cu102/torch_stable.html

2. 查看cuda的安装版本和位置
   nvcc -V
   set cuda
   
   

3. 显卡为NVIDIA GTX 1660 super
   
4. 其他电脑设置如下：
   

代码解释

其他知识

1. torchvision

构成：

• torchvision.datasets：常用的数据集接口
• torchvision.models：常用的模型结构，譬如AlexNet，VGG， ResNet
• torchvision.transforms：图片变换
  • transforms.CenterCrop 对图片中心进行裁剪
    transforms.ColorJitter 对图像颜色的对比度、饱和度和零度进行变换
    transforms.FiveCrop 对图像四个角和中心进行裁剪得到五分图像
    transforms.Grayscale 对图像进行灰度变换
    transforms.Pad 使用固定值进行像素填充
    transforms.RandomAffine 随机仿射变换
    transforms.RandomCrop 随机区域裁剪
    transforms.RandomHorizontalFlip 随机水平翻转
    transforms.RandomRotation 随机旋转
    transforms.RandomVerticalFlip 随机垂直翻转
• torchvision.utils：其他操作

2. PIL：Python Image Library

是Python 语言的一个第三方库，支持图像存储、显示和处理，能够处理几乎所有格式的图片。

3. torch

• 3.1 torch：生成随机数字的tensor，满足标准正态分布（0~1）

print(torch.randn(3),'\n',
      torch.randn(3, 4),'\n',
      torch.randn(3, 4, 5))

#切换环境，推出环境直接exit()即可
(base) C:\Users\wpyoung>conda activate pytorch_gpu
(pytorch_gpu) C:\Users\wpyoung>

conda search pytorch
# 可能搜索不到，再添加1个源
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/

# 查看已经安装的包
conda list

• 去官网生成命令
  

conda install pytorch torchvision torchaudio pytorch-cuda=11.7 -c pytorch -c nvidia

出现的问题

• conda uninstall torch 报错
  但是pip uninstall torch可行

# 此前使用过conda unisntall torchvision
(pytorch_gpu) C:\Users\wpyoung>conda uninstall torch
Collecting package metadata (repodata.json): done
Solving environment: failed

PackagesNotFoundError: The following packages are missing from the target environment:
  - torch

(pytorch_gpu) C:\Users\wpyoung>conda uninstall torchaudio
Collecting package metadata (repodata.json): done
Solving environment: failed

PackagesNotFoundError: The following packages are missing from the target environment:

解决：

(pytorch_gpu) C:\Users\wpyoung>pip uninstall torch
Found existing installation: torch 1.10.1+cu102
Uninstalling torch-1.10.1+cu102:
  Would remove:

Proceed (Y/n)? Y
  Successfully uninstalled torch-1.10.1+cu102

• 但是导入torchvision会报错，torchvision需要安装与pytorch对应的版本，否则会报错？
