列表索引錯誤我是新來numba/numbapro。我試圖運行的一個例子，這一個關於廣義Ufuncs與guvectorize：與numba guvectorize
（下面的鏈接爲例）：http://docs.continuum.io/numbapro/quickstart.html#numbapro-guvectorize
import numbapro as numbapro
@numbapro.guvectorize(['void(int32[:], int32[:])'], '(n)->()')
def sum_row(inp, out):
"""
Sum every row
function type: two arrays
(note: scalar is represented as an array of length 1)
signature: n elements to scalar
"""
tmp = 0.
for i in range(inp.shape[0]):
tmp += inp[i]
out[0] = tmp
我得到這個錯誤：
IndexError Traceback (most recent call last)

我沒有找到比這個鏈接更多的文檔。難道我做錯了什麼？我發現在簽名中有一個空支架時會發生這種情況。 我在Linux機器上運行此，我numbapro的版本是提前0.14.1
