我想使用一个给我一个动态数组的库。动态数组结构有一个属性with tf.Session() as sess:
with tf.variable_scope('experiment'):
a = tf.get_variable('a', [1000,24,128], dtype=tf.float32, initializer=tf.random_normal_initializer(stddev=0.1) )
b = tf.get_variable('b', [1000,15,128], dtype=tf.float32, initializer=tf.random_normal_initializer(stddev=0.1) )
c = tf.get_variable('c', [1000,24,15], dtype=tf.float32, initializer=tf.random_normal_initializer(stddev=0.1))
for i in range(1000):
ai = tf.slice(a,[i,0,0],[1,-1,-1]) # (1,24,128)
bi = tf.slice(b,[i,0,0],[1,-1,-1]) # (1,15,128)
aii = tf.reshape(ai, [ int(ai.get_shape()[1]), int(ai.get_shape()[2])] ) # (24, 128)
bii = tf.reshape(bi, [ int(bi.get_shape()[1]), int(bi.get_shape()[2])] ) # (15, 128)
ci = contract_func(aii,bii) # (24,15)
c[i] = ci
，它给出了数组的开头。
在构建列表之后，我想在cython中访问此指针（以制作数组的副本）。但我似乎无法从结构中获取指针元素。
这是我的pyx：
void* _heap_ptr这是错误消息：
cimport src.clist as l
def main():
cdef l.ptr_list basic_list
cdef int i = 42
basic_list = l.create_list_size(sizeof(i), 100)
l.list_add_ptr(basic_list, &i)
cdef int* arr;
arr = basic_list._heap_ptr
for i in range(1):
print(arr[i])
我的pxd：

如何修复我的代码？为什么会这样？根据我的调查，如果您忘记将某些内容声明为C（例如，使用malloc而不是libc.stdlib.malloc，那么会弹出错误消息，但我无法看到此处发生类似的事情。）
