我一直在尝试从requirements.txt文件安装软件包，但出现错误。我制作了一个虚拟环境来安装软件包，但安装了庞大的阵列。我的机器在python 3.8上运行
以下是我在虚拟环境中尝试安装requirements.txt文件时在终端中遇到的错误
Getting requirements to build wheel ... done

尝试隔离需求的哪一行.txt会给您带来错误，您可以尝试注释掉割炬，并查看没有它的安装过程。
要复制您的错误消息，请尝试使用pip install火炬，它会给您您遇到的错误消息。
此后有两件事：
此外，您可能想安装Anaconda软件包，以尝试是否有大多数库。
作为一个旁注-在安装一些严重的依赖项时经常会遇到不好的经验，因此将其视为专业知识，这不是您做错的事情，这是您尝试使用的依赖项的性质。祝你好运！
