numba jit:'DataFlowAnalysis'对象没有属性'op_STORE_DEREF'

Question

我正在尝试使用numba运行以下代码但是收到错误:

from numba import jit

@jit(nopython=True)
def create_card_deck():
    values = "23456789TJQKA"
    suites = "CDHS"
    Deck = []
    [Deck.append(x + y) for x in values for y in suites]
    return Deck

create_card_deck()

任何导致此错误的建议都表示赞赏:

'DataFlowAnalysis' object has no attribute 'op_STORE_DEREF'

Answer 1

这里有两个问题 - 更基本的问题是numba不支持nopython模式中的字符串

@jit(nopython=True)
def create_card_deck():
    values = "23456789TJQKA"
    suites = "CDHS"
    return values

In [4]: create_card_deck()
---------------------------------------------------------------------------
NotImplementedError : Failed at nopython (nopython mode backend)
cannot convert native str to Python object

该特定错误是因为nopython模式当前也不支持列表推导.
