在下载包时出现下面的错误：
userdeMBP:pytorch user$ conda install -n deeplearning matplotlib
Solving environment: failed
CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/osx-64/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.
ConnectionError(MaxRetryError(‘HTTPSConnectionPool(host=\‘repo.anaconda.com\‘, port=443): Max retries exceeded with url: /pkgs/main/osx-64/repodata.json.bz2 (Caused by ReadTimeoutError("HTTPSConnectionPool(host=\‘repo.anaconda.com\‘, port=443): Read timed out. (read timeout=9.15)"))‘))
一开始是调用config命令去设置清华的镜像：
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/c conda config --set show_channel_urls yes //设置配置中的参数 conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/ conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/
但是还是出错：
(deeplearning) userdeMBP:~ user$ conda install matplotlib
Solving environment: failed
CondaHTTPError: HTTP 404 NOT FOUND for url <https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/c/noarch/repodata.json>
Elapsed: 00:00.226091
The remote server could not find the noarch directory for the
requested channel with url: https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/c
As of conda 4.3, a valid channel must contain a `noarch/repodata.json` and
associated `noarch/repodata.json.bz2` file, even if `noarch/repodata.json` is
empty. please request that the channel administrator create
`noarch/repodata.json` and associated `noarch/repodata.json.bz2` files.
$ mkdir noarch
$ echo ‘{}‘ > noarch/repodata.json
$ bzip2 -k noarch/repodata.json
You will need to adjust your conda configuration to proceed.
Use `conda config --show channels` to view your configuration‘s current state.
Further configuration help can be found at <https://conda.io/docs/config.html>.
后面发现可能是这个镜像的问题，打开本地的.condrac文件，将设置的channels改成：
- https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/ - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/bioconda/
后面再运行就发现成功了

之后如果设置了另一个函数再次进行install时，明明之前已经更改了channels，但如果还是遇见了这样的问题：
(deeplearning2) userdeMBP:neural transfer user$ conda install matplotlib Solving environment: failed CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/r/osx-64/repodata.json.bz2>
解决办法就是退出该环境，使用-n来指明下载的环境，这样就不会出现这样的问题了：
userdeMBP:pytorch user$ conda install -n deeplearning2 matplotlib
