将numpy 2D双复数数组传递给cython作为memoryview

Question

以下代码在jupyter笔记本中失败。但是，如果我使用double而不是double complex，则一切正常。

%%cython 
cpdef test_array(double complex [:,::1] test):
    cdef int x1,y1 
    x1,y1 = test.shape[0],test.shape[1]
    for i in range(x1):
        for j in range(y1):
            test[i][j]+=0

双重复杂的错误是：

我需要在函数外使用numpy并将其作为memoryview传递，以启用使用nogil的并行操作。
