Error in dimensions when using InteractionTransformer

Dear jlevy44,

I wanted to use the InteractionTransformer in combination with the XGBClassifier. Following your demo on GitHub, I run:

from xgboost import XGBClassifier
transformer=InteractionTransformer(untrained_model=XGBClassifier(random_state=42, tree_method='hist'),max_train_test_samples=1000,mode_interaction_extract=int(np.sqrt(X_train.shape[1])))
transformer.fit(X_train,y_train)

Where my X_train and y_train are dataframes with shape (700000,39) and (700000,1), respectively.

I get the following error:
---------------------------------------------------------------------------------

I then tried it with the data provided in your demo and everything worked fine. Do you know what could possibly go wrong?

Thanks in advance,

Have you tried installing the package directly from github?

pip install git+https://github.com/jlevy44/InteractionTransformer

I downloaded the script from your GitHub and imported it into my notebook. If I install it directly from the GitHub I get the following error:

PicklingError: Can't pickle <class 'xgboost.libpath.XGBoostLibraryNotFound'>: import of module 'xgboost.libpath' failed

I find this strange, as I already imported xgboost before I run the InteractionTransformer

[jlevy44]

I believe this could be due to the version of XGBoost that has issues with pickling the model. I believe downgrading XGBoost to 1.0.0 works if my memory serves me or alternatively specifying "single-threaded" for the dask_scheduler option, which should not pickle XGBoost but will take longer to run.

I am using the 1.0.0 version of XGBoost. I solved the pickle error, basically a file was missing. However, after running it with (and without) direct installation of the package directly from GitHub, I run again into the first error (Shape of passed values is (39, 1), indices imply (39, 39))

[jlevy44]

Hmm.. this should not happen. Are you running a multiclass problem? Before updating the package, can you also try deleting the "dist" directory if you are cloning the repo? This can cause issues.

It is a binary problem. I implemented your suggestion and it still does not run.

I experimented a bit. The code runs without problems for regression problems, but the aforementioned error occurs when a user opts for a binary problem

[jvdboogaard]

I have the same issue as the above. Did you already find the solution to the problem @jlevy44 ?

I have also tried it with your PythonDemo (example), but I get the same error. My code is as follows:

Which gives me the following error:

Can you please help me with this error. I am writing my thesis for the master quantitative finance (in the Netherlands) and I am using the interaction transformer from your paper as part of my research. I am very interested to know whether it works on my data set (credit scoring), but I can't fix this issue.

Wkr,
Jeroen

Hi all, were you able to work through these issues? Forking the repo and testing? I can get to this soon if there is still need.
