在 Python 中安装 Cupy 时出错

  • 772

重新安装 Windows 10、Microsoft Visual C++ 和 CUDA 11.6 后，我安装了 Python 3.10 库。要安装 Cupy，我使用以下命令pip install cupy-cuda116：pip install cupy和pip install cupy-10.5.0+cuda116-cp310-cp310-win_amd64.whl. 一个错误：

  note: This error originates from a subprocess, and is likely not a problem with pip.

    安装“Visual Studio”或在​​“Visual Studio Installer”中，选中“桌面开发”，它将安装大约 10 GB。安装 CUDA，可以从 Nvidia 网站下载。之后使用命令在命令行上安装“Cupy” pip install cupy-cuda116（其中“116”是 CUDA 版本 11.6）。在 Python 中，检查是否安装了 Cupyimport cupy
