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):

@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. 😄
