解决 IndexError: arrays used as indices must be of integer (or boolean) type

使用sklearn处理数据，进行数据标签分类转化，报错如下：

Traceback (most recent call last):
File “.py", line 67, in
pa = le.ina(pa)
File "/rel.py”, line 14, in inform
return s*s_[y]
IndexError: arrays used as indices must be of integer (or boolean) type

解决方法：

s = s.astype('int64')
s = le.inverse_transform(s)
