I have tried numerous ways to install PyTorch:

我尝试了许多安装PyTorch的方法：

• !pip install torch --index-url=https://pypi.org/simple/


• !pip cache purge


• !conda install pytorch torchvision torchaudio cudatoolkit=10.2 -c


• pytorch !pip install torch

and i have had no luck!
i am new to this so im not sure if thi si s a simple fix but i alos tried opening anaconda prompt and using:

我没有运气！我是新手，所以我不确定这是否是一个简单的修复方法，但我也尝试过打开anaconda提示符并使用：

• (base) C:>conda install pytorch torchvision torchaudio cpuonly -c pytorch

However i got this error: CondaHTTPError: HTTP 000 CONNECTION FAILED for url https://conda.anaconda.org/pytorch/win-64/current_repodata.json
Elapsed: -

然而，我得到了这个错误：CondaHTTPError：url的HTTP 000连接失败https://conda.anaconda.org/pytorch/win-64/current_repodata.json运行时间：-

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.
'https//conda.anaconda.org/pytorch/win-64'

尝试检索此URL时发生HTTP错误。HTTP错误通常是间歇性的，一次简单的重试就会让你如愿以偿https://conda.anaconda.org/pytorch/win-64'

Lastly i tried this, and also got no where!

最后我试了一下，但也没有成功！

(base) C:>echo "$http_proxy"
"$http_proxy"

（基本）C:>echo“$http_proxy”“$http_poxy”

(base) C:>proxy_servers:
'proxy_servers:' is not recognized as an internal or external command,
operable program or batch file.

（基本）C:>proxy_servers:'proxy_servers:'未被识别为内部或外部命令、可操作程序或批处理文件。

Please help! if you could answer in the simplest way possible with steps for me to take that would be greatly appreciated! as i am still teaching myself so i may find it hard to understand!

请帮忙！如果你能以最简单的方式回答，并为我采取步骤，我将不胜感激！因为我还在自学，所以我可能会觉得很难理解！

Thank you!

非常感谢。
