In python's pandas, when statistical aggregation, there is a version problem, indicating that the dictionary format is not supported.
For example, the following code can be changed like this.
words_stat = words_df.groupby(by=['segment'])['segment'].agg({"计数": numpy.size})
上面代码改成下面代码就可以了。应该是版本问题。
word_stat = word_df.groupby(by=['segment'])['segment'].agg(np.size)
word_stat = word_stat.to_frame()
word_stat.columns = ['计数']
