Matlab 在尝试调用 Python 的 execfile 函数时崩溃

Question

我试图从 Matlab 中调用一个简单的 Python 脚本，不幸的是 Matlab 崩溃了。 我在 Windows 10 上。我通过在 Matlab 的交互式命令窗口中调用py.execfile(filePathAndName)来做到这一点。

我的 Matlab 当前指向 Anaconda 发行版，但如果我将其指向原始 CPython 发行版，它也会以相同的方式崩溃。

错误如下。

奇怪的是，如果我只是在 Matlab 中调用py.help('execfile')这工作正常。

>> py.help('execfile')
Help on built-in function execfile in module __builtin__:

execfile(...)
    execfile(filename[, globals[, locals]])
    
    Read and execute a Python script from a file.
    The globals and locals are dictionaries, defaulting to the current
    globals and locals.  If only globals is given, locals defaults to it.

这是我调用py.execfile(filePathAndName)时的错误：

Answer 1

我遇到了同样的问题。 解决方案是提供一个工作空间参数。 正如 py.eval 所描述的那样： 调用 Python eval 函数。 例如，您可以尝试：

ws=py.dict;
py.execfile(filePathAndName,ws)

这应该运行没有错误或崩溃 MATLAB。
