我需要从我的模块中调用Python函数并为其设置两个参数：int和array。在

现在我在调用这个函数的时候遇到了segfault，我不知道我做错了什么。有人能指出我的错误在哪里吗？在

函数在我的Python模块中应用程序副本. 如果我从Python代码调用它，它会起作用：def get_model(rate, signal):

mfcc_train = MFCC().compute(rate, signal)

with open('mfcc_test', 'wb') as f:

pickle.dump(mfcc_train, f)

return clf()._fit(mfcc_train)

调用上面函数的C代码。最后一个春天是“打电话前”

^{pr2}$

UPD:更新代码，其中一个问题已修复。但另一个问题仍然存在。它在PyObject* pSamples = PyArray_SimpleNewFromData(1, dims, NPY_INT8, (void*)samples);行。我也不知道是怎么回事。在

和wav.h以防万一：#include
