我有一些想要尽快运行的 Cython 代码。我是否需要释放 GIL 才能执行此操作？

假设我的代码与此类似：

import numpy as np

# trivial definition just for illustration!
cdef double some_complicated_function(double x) nogil:
    return x

cdef void func(double[:] input) nogil:
    cdef double[:] array = np.zeros_like(input)
    for i in range(array.shape[0]):
        array[i] = some_complicated_function(input[i])

我从np.zeros_like类似于以下内容的行中收到大量错误消息：

nogilcode.pyx:7:40: Calling gil-requiring function not allowed without gil
nogilcode.pyx:7:29: Accessing Python attribute not allowed without gil
