未编码的列

Question

我有一个名为“教育”的专栏。我正在尝试使用标签编码器对其进行编码，但弹出以下错误

[我无法 post 图片，所以 link 数据附在下面][1]

TypeError                                 Traceback (most recent call last)

    112         try:

    114         except TypeError:

     62         uniques = np.array(uniques, dtype=values.dtype)

TypeError: '<' not supported between instances of 'str' and 'float'

During handling of the above exception, another exception occurred:

Answer 1

你可以试试这个


df_temp['education']=encoder1.fit_transform(df_temp['education'].astype(str))

未编码的列

Column not being encoded

python

encoder
