M1安装 cvxpy cvxopt python3.8.2

python3.8.2

安装cvxpy

官网installation安装先试一遍 不行再考虑下面的
要先 brew install cmake
https://www.cvxpy.org/install/index.html

Apple M1 users have had trouble installing CVXPY using the commands above. 
That trouble stemmed partly from a configuration error in CVXPY’s pyproject.toml, which has been fixed in CVXPY 1.1.19 and 1.2.0. 
If you have those versions (or newer) then the above commands should work provided (1) you have cmake installed via Homebrew and (2) you have an ECOS 2.0.5 wheel. 
The cmake requirement stems from OSQP and there appear to be problems building more recent versions of ECOS on M1 machines. See this comment on the CVXPY repo and this issue on the ECOS repo for more information.

指定安装ecos的版本
ecos==2.0.5
pip安装cvxpy还是出错

我的方法：

依赖库要全部先安装好下载源码 source code 安装

If you want to use CVXPY with editable source code, run

pip install -e .
otherwise, run

pip install .

输入命令：arch -x86_64 pip install -e .

arch -x86_64 pip install -e .

我如果强行arch -x86_64 pip install cvxpy
虽然可以安装成功 但是_cvxcore.cpython-38m-darwin.so会出问题
大概错误长的样子：import _cvxcore ImportError: dlopen(---- (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')), '/usr/lib/libxcrun.dylib' (no such file)).
大概意思就是需要的是arm64的 给的文件名不对…所以不行

安装cvxopt

pip install cvxopt报错

尝试的方法1

https://blog.csdn.net/weixin_34219944/article/details/91918784

第一步：brew tap homebrew/science出错

==> Homebrew is run entirely by unpaid volunteers. Please consider donating:

Error: homebrew/science was deprecated. This tap is now empty and all its contents were either deleted or migrated.

不行

尝试的方法2

官网
下源码安装

xcode-select -p

brew install gsl fftw suite-sparse glpk
git clone https://github.com/cvxopt/cvxopt.git
cd cvxopt
git checkout `git describe --abbrev=0 --tags`
export CVXOPT_BUILD_FFTW=1    # optional
export CVXOPT_BUILD_GLPK=1    # optional
export CVXOPT_BUILD_GSL=1     # optional
python setup.py install

要是直接下载下来的话直接进文件夹就行了…
