我正在尝试在 Nipype 上运行一个简单的 matlab 界面，如下所示，但不知何故它卡在了 run() 代码中。我的命令行不再继续。但是，如果我复制 mlab.cmdline (matlab -nodesktop -nosplash -singleCompThread -r "addpath('/somepath');pyscript;exit") 并将其传递到命令行，它会完美运行。
import nipype.interfaces.matlab as matlab
mlab = matlab.MatlabCommand()
mlab.inputs.script = """ 1+2 """
print mlab.cmdline
res = mlab.run()
print res.runtime
这是 ipython 键盘中断：
