Question

我正在尝试连接，但结果却提到了错误。我也是python的新手。

def cving(x1, x2, x3, x4, x5, y1, y2, y3, y4, y5, ind1, ind2, ind3, ind4, ind5, num):

if num == 0:
    xwhole = np.concatenate((x2, x3, x4, x5), axis=0)
    yhol = np.concatenate((y2, y3, y4, y5), axis=0)
    return x1, y1, ind1, xwhole, yhol
elif num == 1:
    xwhole = np.concatenate((x1, x3, x4, x5), axis=0)
    yhol = np.concatenate((y1, y3, y4, y5), axis=0)
    return x2, y2, ind2, xwhole, yhol
elif num == 2:
    xwhole = np.concatenate((x1, x2, x4, x5), axis=0)
    yhol = np.concatenate((y1, y2, y4, y5), axis=0)
    return x3, y3, ind3, xwhole, yhol
elif num == 3:
    xwhole = np.concatenate((x1, x2, x3, x5), axis=0)
    yhol = np.concatenate((y1, y2, y3, y5), axis=0)
    return x4, y4, ind4, xwhole, yhol
else:
    xwhole = np.concatenate((x1, x2, x3, x4), axis=0)
    yhol = np.concatenate((y1, y2, y3, y4), axis=0)
    return x5, y5, ind5, xwhole, yhol

以下是x1，x2，x3和x4的一些输出*显示用于np.concantate的一些输出

Answer 1

错误消息显示全部：x1是2D而x4是1D。连接它们毫无意义。您需要确保所有级联数组具有相同的维度，例如通过向所有1D数组添加维度

x4 = x4[:, np.newaxis]

Np.concatenate ValueError：所有输入数组必须具有相同的维数
