我也 100% 需要这部分，因为我在 nums 中：
总和 += i。像这样的迭代不会占用大量内存，因为它不断计数而不是具有大块内存和平的迭代。提前致谢！

【问题讨论】：

我不明白你的问题。你在使用 numpy 数组吗？为什么你认为array.index(max(array)) 会更快？这意味着您使用的是list?
如果您提供真实示例数据，这将非常有帮助，其中包含您的代码应该做什么的完整描述，包括您输入的相应输出
numpy 数组没有 index 方法。您的变量名称和问题应该反映这种差异。例如alist.index....

标签： python numpy argmax

【解决方案1】：

np.argmax 并不比 array.index(np.max(array)) 慢，但是 list_mean 可以更高效：如果你想要一个完整的 python 实现，你可以使用

sum(nums)/len(nums)

甚至更高效：

np.mean(nums)

（您已经使用过数组）

【讨论】：

对不起，我的代码运行得更快，但我真的需要加快速度。
我进行迭代，因为它占用的空间更少：for i in nums: sumof += i.如您所见，我有很多数据
你能显示更完整的代码吗？事实上，很难理解你的代码是做什么的，上下文等......可以肯定的是，优化问题不是来自 argmax，它可能更大。
据我所知，你没有那么多数据..

【解决方案2】：

或多或少：进口时间将 numpy 导入为 np
