打印 numpy 数组的所有列和行
问题描述：
如截图所示，二维 numpy 数组被截断用于打印目的.我想显示所有元素.是否有启用该行为的选项设置?
As shown in the screenshot a 2D numpy array is truncated for printing purposes. I would like to have all elements displayed. Is there an option setting to enable that behavior?
答
参见 有关打印选项的文档.具体:
阈值:整数，可选
触发汇总而不是完整repr的数组元素总数(默认为1000).
Total number of array elements which trigger summarization rather than full repr (default 1000).
因此将 threshold 设置为 np.inf 意味着它永远不会被汇总.
So setting threshold to np.inf means it is never summarized.
np.set_printoptions(threshold=np.inf)
