import_optional_dependency（）得到了一个意外的关键字参数错误

Question

我正试图与Featuretools合作，为客户流失数据集开发一个自动化的特征工程工作流。最终结果是一个函数，它接收数据集并为客户标记时间，并构建可用于训练机器学习模型的特征矩阵。

作为本练习的一部分，我尝试执行以下用于绘制直方图的代码，并得到“TypeError:import_optional_dependency（）得到一个意外的关键字参数'errors'”。请帮助解决此类型错误。

import matplotlib.pyplot as plt
%matplotlib inline
plt.style.use('fivethirtyeight')
plt.rcParams['figure.figsize'] = (10, 6)

trans.loc[trans['actual_amount_paid'] < 250, 'actual_amount_paid'].dropna().plot.hist(bins = 30)
plt.title('Distribution of Actual Amount Paid')

以下是我收到的全部错误：

尝试升级熊猫：

pip install pandas --upgrade
