so i have tried to update the notebook a couple of times. dropping specific columns which i think is the only difference with the current data. however i keep getting the above error and i am not sure where i am going wrong.
Many thanks for your help.
Best,
Andrew

hi, it's hard to see what's going on, please share the code. maybe the class variable is the first feature instead of the last one? kindly regards,

ok, will forward the code

[AIAdventures]

I have just sent you email with my code attached.

Almost certain it's the extra variables that are causing the problem but I can't seem the get the entire notebook the run.
Many thanks,
Best,
Andrew

[algonell]

hi, it's related to: target = train_data['target'] train_data = pd.DataFrame(poly.transform(train_data.values[:,:-1])) test_data = pd.DataFrame(poly.transform(test_data.values)) train_data['target'] = target.values be sure to have a copy of 'target' column before and after Poly features fit and transform. make sure you run the cells in the right order, it's exactly like my ongoing code. kindly regards,

I have tried it, keep getting an error.

[AIAdventures]

[AIAdventures]

in my data set come NAN values on the last column.

[algonell]

try running without the Poly features, check if the entire flow works.
