Question

我正在尝试在Nipype上运行一个简单的matlab接口，如下所示，但不知怎的，它被卡在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”）并将其传递给命令行，它就能完美运行。

import nipype.interfaces.matlab as matlab

mlab = matlab.MatlabCommand()
mlab.inputs.script = """ 1+2 """

print mlab.cmdline
res = mlab.run()

print res.runtime

这里是ipython键盘中断：

我已阅读此网站中的其他subprocess个问题但这些问题都与Popen()有关。在我看来poller.poll()有问题。当它到达这一行时它不再处理。

Answer 1

我没有复制这种行为（又名“适合我！”）。您使用的是哪种版本的nipype？

subprocess陷入poller.poll（）
