I’m running the above code. I encountered a problem when running the last line. It said NameError: name 'TabularList' is not defined . I tried from fastai.tabular.data import TabularList but encountered another problem ImportError: cannot import name 'TabularList' from 'fastai.tabular.data' (D:\anaconda3\lib\site-packages\fastai\tabular\data.py) . Does anyone meet the same problem? Could anyone help me? thank you very much in advance!

I have the same problem.

Any reason that explain this error and how to solve it ?

If you’re getting this now it may be because you’re using fastai 2.0+, which does not have the TabularList API anymore, it’s now TabularPandas and a bit different of an API (though some things are similar enough)

Ok I’ll read the documentation and see how to use Tabular Pandas instead. thank you
