在终端中安装 matlab python 包后,使用:
cd "matlabroot\extern\engines\python"
python setup.py install
并试图运行它,我得到一个段错误:
:~$ python

>>> import matlab.engine
Segmentation fault: 11
但是,我可以通过设置 DYLD_LIBRARY_PATH 来解决这个问题,之后 matlab.engine 工作:
:~$ export DYLD_LIBRARY_PATH=/System/Library/Frameworks/Python.framework/Versions/Current/lib:$DYLD_LIBRARY_PATH
:~$ python

>>> import matlab.engine
>>> eng = matlab.engine.start_matlab()
>>> exit()
但是,当我之后尝试启动 iPython 时,出现此错误:

如您所见,python 版本不同。我认为这是我的系统 Python 和 Anaconda 之间的冲突,但我不确定如何解决它,非常感谢任何帮助。谢谢。
