Python 如何删除多维列表中的列表？

我有一张8，20400号形状的清单。如何删除该8，或者是否可以将20400指定为输入维度？非常感谢。 这是numpy文件

有8个这样的数组。

正如评论中指出的

import numpy as np
A = np.ndarray(shape=(8, 20, 400))
print (A.shape)      ## Prints (8, 20, 400)
print (A[0].shape)   ## Prints (20, 400)

您只需执行大列表[0]。这将为您提供8个选项中的前20400个。现在只有20400了。你在用numpy吗？820400意味着你基本上有一个20400形状的8个数组的列表。你可以选择任何一个。我用的是numpy。我想将此列表作为kmeans集群的输入，但error found dimension=3类似于此。这20个都是1级聚类的质心。我不知道8是什么，但是每增加25个属于单个动作类的视频，第一维度就会增加4。关于那个大列表[0]，我现在正在运行一个实例。我很快会更新
