Question

我正在尝试重新创建一张图片。我拍了一张照片并将其保存。在我做了灰度并保存之后。找到两个图像的常见像素，我试图再次重新创建图片，我得到这个错误。这是一条道路的图片，我试图只保留白色车道。因此，在我将边缘图片与第一张图片进行比较后，最常见的像素是代表道路车道的白色像素。

在代码清单

附近标记为＆lt; -----的行中引发错误

TypeError: too many data entries

newpic是`[1,1,1,1，...，1]

Answer 1

在这种情况下，这意味着您放置的数据超过了您之前设置的大小。您可以检查使用len（the_list_of_data）放入的数据的长度，因此，每次放入数据（即使覆盖）时，长度都会增加一倍。您可以将_list_of_data长度设置为0，然后用数据填充它。此错误也会在循环中发生。
