使用conda安装pytorch时出现问题CondaSSLError: OpenSSL appears to be unavailable on this machine.

1、问题：使用conda安装pytorch时出现问题

conda install pytorch torchvision torchaudio cudatoolkit=11.3 -c pytorch

2、报错：

Collecting package metadata (current_repodata.json): failed
CondaSSLError: OpenSSL appears to be unavailable on this machine. OpenSSL is required to
download and install packages.
Exception: HTTPSConnectionPool(host='mirrors.tuna.tsinghua.edu.cn', port=443): Max retries exceeded with url: /anaconda/cloud/peterjc123/win-64/current_repodata.json (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available."))

3、原因：由报错信息猜测需要下载安装OpenSSL。 下载链接
4、结果：pytorch可以正常安装。
