@vkhodygo It was but I just fixed it myself.
@bmreiniger thanks for the suggestion. I've implemented this and wrote a test based on @willsthompson 's data.
from category_encoders.
It looks like this is due to the underlying ordinal encoder converting the timestamps (and so is likely to affect other encoders as well):
>>> cat_encoder.ordinal_encoder.mapping
[{'col': 'TIMESTAMPS', 'mapping': 8.732448e+17 1
9.679392e+17 2
9.364032e+17 3
9.994752e+17 4
NaN -2
dtype: int64, 'data_type': dtype('<M8[ns]')}, {'col': 'FLOATS', 'mapping': 0.285652 1
0.900217 2
0.928511 3
0.566326 4
NaN -2
dtype: int64, 'data_type': dtype('float64')}]
and then
>>> cat_encoder.mapping['TIMESTAMPS']
NaN 1.0
Name: TIMESTAMPS, dtype: float64
In this diff: d19f69e
it seems that categories.tolist()
converts numpy timestamps where list(categories)
doesn't (?).
from category_encoders.
Do you still think this is actual?
