import paddle
import numpy as np

x_arr = np.array([], dtype=np.float32)
x = paddle.to_tensor(np.reshape(x_arr, (0, 0, 0)))

starts = paddle.to_tensor(np.reshape(np.array([], dtype=np.int32), (0,)))
ends = paddle.to_tensor(np.reshape(np.array([], dtype=np.int32), (0,)))

避免以下两种情况触发段错误

paddle.slice(x, [], starts, ends)
paddle.slice(x, [-1000000], starts, ends)
