我需要從我的模塊中調用Python函數并為其設置兩個參數:int和array。在
現在我在調用這個函數的時候遇到了segfault,我不知道我做錯了什么。有人能指出我的錯誤在哪里嗎?在
函數在我的Python模塊中應用程序副本. 如果我從Python代碼調用它,它會起作用: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)
調用上面函數的C代碼。最后一個春天是“打電話前”

UPD:更新代碼,其中一個問題已修復。但另一個問題仍然存在。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以防萬一:#include
