python pandas concat：ValueError：传递的值的形状为（4，9），索引暗示（4，5）

Question

我正在登录各种网络设备，并尝试连接输出。 下面是我正在运行的脚本，它运行正常。 我在尝试连接po1，allin1，sta1，saa1，stn1的输出时遇到问题。 我已经给出了下面所有变量的输出。 如果其他索引中没有任何索引，则po1将是此处的源，它需要显示“ NAn”。 如果您对理解问题有疑问，请告诉我。

以下是我得到的错误。 当我将轴= 1时出现此错误。

添加dropduplicates后得到输出，并使用merge代替concat 。

po1_n = po1.drop_duplicates()
allin1_n = allin1.drop_duplicates()
sta1_n = sta1.drop_duplicates()
saa1_n = saa1.drop_duplicates()
stn1_n = stn1.drop_duplicates()
csv_data1 = po1_n.merge(allin1_n, on='Interface', how='outer').merge(sta1_n, on='Interface', how='outer').merge(saa1_n, on='Interface', how='outer').merge(stn1_n, on='Interface', how='outer')
