TypingError：在 nopython 模式管道中失败（步骤：nopython 前端）解析“$112binary_subscr.7”的属性“isScEtaEE”类型时出现内部错误。模块“numba”没有属性“bool”期间：在 (19) 处键入 get 属性以在调试级别启用日志记录以获取详细信息。文件“”，第 19 行：def make_vid_plot(Photon):
print(Photon[eventIdx][phoIdx].isScEtaEE) # isEcEtaEE 是布尔值 ^

我正在将 numba 与 Coffea 一起使用，但是，带有布尔值的 Numba 现在似乎正在工作。
如何解决这个错误？

numba 版本：0.51.2

谢谢

实际上，这是在PR #776main中修复的 Awkward Array 中的一个错误，当您阅读本文时，它可能会合并到分支中。

我认识到很难将用户错误与内部错误与错误消息区分开来 - Awkward Array 中的一般规则RuntimeError是内部错误，ValueError是用户错误 - 但是当 Numba 尝试确定类型时出现任何错误as TypeError，不管它是什么。（在这种情况下，它是一个AttributeError! 它试图numba.bool在正确的拼写是 时访问numba.boolean。）

但是，如果您认为某事可能是错误，则将其报告为GitHub 问题会更容易。打印出整个错误消息也很有帮助，如下所示：

幸运的是，您引用的错误消息部分包括“ module 'numba' has no attribute 'bool'”部分，这给了我一个开始的地方。但是理解这个Photon虚拟数组的错误至关重要——错误numba.bool发生在虚拟数组处理中。（Coffea NanoEvents 是虚拟的——它们按需从 ROOT 文件中读取数据，甚至在 Numba JIT 编译的函数中。）完整的错误消息包括这个数组具有VirtualArrayType.

最好的错误报告包括一些重现问题的数据（例如，您是如何获得Photon对象的？），但GitHub 问题模板会提示您这样做。

不过，感谢您报告这个！任何报告都有帮助！
