很久很久没打开pycharm了，一打开还是配不出环境来。。。先放几个帮助比较大的链接吧

pytorch官网
 安装以前版本

查看最高可安装的cuda版本，在cmd命令行中输入：

nvidia-smi

在这里插入图片描述
本次决定安装CUDA11.6。我在终端输入：

conda install cudatoolkit=11.6

显示如下：

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

按照一些博主所说的，查看可以安装的cuda版本：

conda search cudatoolkit

显示依然如下：

试了很多命令显示都是这样。
后来我按照link1中给出的方法，将原来的 .condarc 中的内容更新如下：

channels:
  - defaults
show_channel_urls: true
default_channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free

  pytorch: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  simpleitk: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud

终于不再出现那个问题了。
接下来我在pytorch官网中查看 CUDA11.6 可以安装的 torch 版本：
在这里插入图片描述
然后在终端中执行命令。很久之后安装好了。
上述库都是使用 conda 命令安装成功的。接下来我又安装了 opencv-python，这时用 conda 命令怎么也安不上，但是改为 pip 命令就成功了。随后又安装了 opencv-contrib-python，也是使用 pip 命令一次就成功了。

顺便记录下我安装其他库的一些过程。
首先是运行代码时出现了如下错误：

ImportError: cannot import name ‘OrderedDict‘ from ‘typing‘ (D:\Anaconda\lib\typing.py)

解决方案如这位大佬所述。

紧接着又出现了如下错误：

ModuleNotFoundError: No module named 'lmdb'

按照这位大佬的方法解决。

紧接着又出现了这个问题：

cv2.error: OpenCV(3.4.14) C:\surf.cpp:1029: error: (-213:The function/feature is not implemented) This algorithm is patented and is excluded in this configuration; Set OPENCV_ENABLE_NONFREE CMake option and rebuild the library in function 'cv::xfeatures2d::SURF::create'
