Anaconda在Linux上安装Matlab引擎

Question

我正在尝试使用anaconda python 3.4在CentOS 7 for Matlab R2016a上安装Matlab Engine for Python。

我执行了以下命令：

source activate py34 # Default is python 3.5
python setup.py install

输出为：

running build
running build_py
running install_lib

它以某种方式将matlab引擎安装到系统的python版本中，而不是anaconda的py34虚拟环境中。我注意到了OSX上的this，它确实在我的mac上工作！有人能帮上忙吗？

Answer 1

只是提醒那些在anacodna文件夹下有多个虚拟env的用户 python setup.py install --prefix="/Users/user/anaconda/" 根据@Leighton的提示，matlab引擎包实际上安装在单独的anacodna3/lib/python2.7/site-package/matlab文件夹下，而不是普通的anaconda3/lib/python3.7/site-package文件夹下。因此，您需要手动将matlab文件夹移动到python正在使用的site package文件夹中。如果有多个虚拟环境，请将其移动到要运行程序的虚拟环境的相应站点包文件夹中。

Answer 2

经过这么多的折磨，我终于用一种简单的方法解决了这个问题。您可以添加python命令的替代命令，而不是通过修改.bash_配置文件将系统配置为使用anaconda的python：

  sudo update-alternatives --install /usr/bin/python python ~/anaconda3/envs/py34/bin/python 2
  update-alternatives --display python
  cd /usr/local/MATLAB/R2016a/extern/engines/python/
  sudo python setup.py install

Answer 3

cd "matlabroot\extern\engines\python"
python setup.py install --prefix="installdir"

对于Unix（OSX10）python2.7，使用Anaconda

cd /Applications/MATLAB_R2015a.app/extern/engines/python
python setup.py install --prefix="/Users/user/anaconda/"
