toad.selection.select 可以处理字符串变量吗？

[hailee8899]

官方文档 https://toad.readthedocs.io/en/latest/tutorial.html
这里的例子并没有说明不支持处理字符串变量。

但是我用了同样的代码和数据，从代码的报错信息来看是不支持的，请大家帮忙解答一下疑惑。

同样的问题，甚至删掉所有字符串还是会报错

我也遇到了这个问题，官方文档上的展示数据中不就有字符串类型的数据吗，但是我运行时报错

下面是报错内容：
selected_data, drop_lst = toad.selection.select(
data_tr,target = 'TARGET',empty = 0.5,
iv=0.05, corr=0.7,return_drop=True
)
Traceback (most recent call last):

selected_data, drop_lst = toad.selection.select(

frame, corr_drop = drop_corr(frame, target = target, threshold = corr, by = weights, return_drop = True, exclude = exclude)

corr = f.corr().abs()

result[rl.indexer] = arr

@hailee8899 @Aryooo @AnnaYang2223 I think its same to #133 , the issue with pandas >=2.0.x, please upgrade toad to 0.1.3 and have a try. 😄
