尝试生成熊猫配对图时的"TypeError: list indices must be integers or slices, not list"

Question

我目前在为线性回归模型生成熊猫配对图时遇到问题。

我已经获得了我需要的数据，经过一些清理和编码，我正在尝试生成配对图。

目前我无法解决我看到的错误：

代码

our_columns = ["PLACE_CP6","RESULT_NOK"]
pd.plotting.scatter_matrix(
df_dummied[our_columns] ## Our dataframe with list of columns
, figsize=(10,10) ## Figure size - changes the size of the graph. Smaller number, smaller graph
, hist_kwds = {'bins': 10}
, alpha = 1  ## Settings for the keywords
, diagonal='hist'
)
plt.show()

---------------------------------------------------------------------------

5         , figsize=(10,10) ## Figure size - changes the size of the graph. Smaller number, smaller graph
6         , hist_kwds = {'bins': 10}
TypeError: list indices must be integers or slices, not list

关闭Jupyter并重新启动后，现在一切正常。
