如何在 VS 代码中安装 CVXOPT
[英]How to install CVXOPT in VS code
问题描述
尝试在 VS 代码中安装 CVXOPT 每次都失败，到目前为止，我尝试使用轮文件、tar 文件、pip install、pip install --user 等进行安装，但每次都失败，并出现我没有的相同错误有一个想法。 (env) PS C:\\Users\\paseckat> python pip install cvxopt
我得到的错误：

根据你提供的信息，当我使用python3.8的pip安装“ cvxopt ”时，遇到了和你一样的情况。
原因：“ cvxopt ”安装依赖“ wheel ”，但“ wheel ”不支持python3.8版本。
在CVXOPT文档中：“Wheels for Windows：可用于 Python 2.7、3.5、3.6和 3.7（仅限 64 位）”
解决方案：
当我使用cvxpot中的 pip 安装“ cvxpot ”时：
另外，你也可以在VSCode的conda环境中使用“ conda install cvxpot ”进行安装，前提是使用的python也是合格的比如Python3.7。
参考： CVXOPT 。

我需要手动安装库。
- 我检查了我的 python 版本：在命令行中：
python --version（我的版本是 3.8.6） - 我将
numpy更新到最新版本：1.19.2
- 从命令行获取 numpy 版本：
python -c "import numpy; print(numpy.version.version)" -
pip install numpy --upgrade
-
1.19.2: 这是 numpy 版本 -
cp38: 这是 Python 版本，如果你有不同的版本，请寻找你的其他版本的numpy+mkl
-
cp38: 这是 Python 版本
- 手动安装：首先必须安装
numpy+mkl
- cd <文件路径>
-
python -m pip install numpy-1.19.2+mkl-cp38-cp38-win32.whlpython -m pip install cvxopt-1.2.5-cp38-cp38-win32.whl
