PyViennaCL安装使用pip

Question

我试图在Windows 10 64位上安装PyViennaCL (https://github.com/viennacl/pyviennacl-dev)，我使用Python 3.9.6。使用pip install pyviennacl，我一开始收到的错误是Visual c++需要的是14.0或更高版本，我通过下载vs buildtools解决了这个问题。现在，我在pip日志中收到了这个错误。

Answer 1

有一个名为Unofficial Windows Binaries for Python Extension Packages的网站，它以二进制形式收集了各种有用的Python库。如果您打算使用库(不打算改变或开发)我建议下载.whl文件的适当版本(根据windows版本，python解释器版本和…)然后在本地安装它，而不是构建二进制文件的复杂过程。幸运的是，那里有几个版本的pyviennacl!

#download proper version 
pip install /path/to/your/downloaded/file.whl
