网站信息推广的策略有哪些动漫网页设计版式
昨天训练数据的时候，发现Anaconda占用C盘达到了20G（暑假在cmd状态下安装的，默认下载到了C盘），心道再创建几个环境，C盘就要爆红了，于是重装Anaconda到了D盘，不过之后的初始化并不顺利--创建pytorch环境总是失败，网上查阅了许多资料：配置path环境变量，关闭VPN，.condarc文件删除或添加路径，更换清华源等等都无果。报错如下：

Conda has prepared the above report.
If you suspect this error is being caused by a malfunctioning plugin,
consider using the --no-plugins option to turn off plugins.Example: conda --no-plugins install <package>Alternatively, you can set the CONDA_NO_PLUGINS environment variable on
the command line to run the command without plugins enabled.Example: CONDA_NO_PLUGINS=true conda install <package>If submitted, this report will be used by core maintainers to improve
future releases of conda.
Would you like conda to send this report to the core maintainers? [y/N]:No report sent. To permanently opt-out, use$ conda config --set report_errors false又看到安装Anaconda时，选择JUST ME默认环境路径在annconda/env下，而选择ALL USERS默认环境路径则在C盘.anaconda/env文件夹下。卸载后又重装了Anaconda，先是选择JUST ME，报相同的错误，又重装后选择ALL USERS，创建pytorch还是相同的错误。
无奈之下，再次把Anaconda安装到C盘，这时候执行conda create -n pytorch python=3.8命令是没问题的，环境可以成功创建。conda activate pytorch激活环境也没问题，不过最重要的一步--安装torch又出错了，pytorch官网的conda代码，清华源，华科源都报相同的错误（上述代码）。Google/GitHub/CSDN/Stack Overflow/博客园等等都查了一遍，都没出现过类似的问题。晚上睡觉的时候心想难道要重装下系统？
还好山重水复疑无路，早上在知乎浏览技术贴的时候看到一句话“pip 或者 conda的时候经常被混合使用，这两者也通常被认为是几乎相同的，尽管他们的很多功能是重叠的。“
突然意识到pip install 和conda install的功能应该是相同的。兴致冲冲在Anaconda Prompt命令行键入：pip3 install torch torchvision torchaudio，等待一段时间后torch终于下载成功。又进入python环境中导入的torch包，输出了torch的版本号
>>> import torch
>>> torch.__version__
'2.1.1+cpu'这下终于尘埃落定，解决掉这个难题了。
