pytorch环境配置踩坑记录

一、问题1

1.执行命令

python 复制代码

conda create -n pytorch python=3.6

2.报错如下

python 复制代码

Solving environment: failed

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/msys2/noarch/repodata.json.bz2>
Elapsed: -

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.

If your current network has https://www.anaconda.com blocked, please file
a support request with your network engineering team.

SSLError(MaxRetryError('HTTPSConnectionPool(host=\'repo.anaconda.com\', port=443): Max retries exceeded with url: /pkgs/msys2/noarch/repodata.json.bz2 (Caused by SSLError(SSLError("bad handshake: Error(【(\'SSL routines\', \'ssl3_get_server_certificate\', \'certificate verify failed\')】)")))'))

3.解决方法

step a:如果C:\Users\用户名这个文件夹没有名为.condarc的文件，执行以下命令创建一个

python 复制代码

conda config --add channels r

step b:打开C:\Users\用户名这个文件夹，找到名为.condarc的文件，将其内容改成以下内容

python 复制代码

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

ssl_verify: false

step c:重新执行以下命令

python 复制代码

conda create -n pytorch python=3.6

二、问题2

1.scipy安装失败后，执行如下命令即可：

python 复制代码

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple scipy

2.参考内容
安装scipy库的时候出现这个问题，请问大佬们该怎么办？
