开发配置规整功能

如果用Titanic数据的话，会推荐以下几个最近的数据集：

self.kND
Out[9]: 
['openml_166905',
 'openml_146578',
 'openml_146602',
 'openml_166906',
 'openml_279',
 'openml_3054']

ND2repo['openml_166905'][0][0]['process_sequence']
Out[11]: 'cat->normed;highC_cat->combined;combined->normed;num->normed;normed->final'
self.config_space.get_hyperparameter('process_sequence').value
Out[12]: 'impute;cat->normed;highC_cat->combined;combined->normed;num->normed;normed->final'

可以看到，推荐的这个数据集并没有impute
