Pipeline Builder - error in running

#1

Hi guys.,
I want to use Pipeline Builder for MultiTaskElasticNet (Linear model category) without Pre-processing step.
my default values are :arrow_down_small:
alpha=0.0001 ,l1_ratio=0.5,max_iter=100,random_state=42
but after many times running I got these error messages :arrow_down_small: :arrow_down_small:
pipelineBuilder-error

what is the reason?

You can see the error, if you click on the bug-icon. Or on the i icon and than on stderr/stdout
in your case one error is:

ValueError: Invalid parameter alpha for estimator ElasticNetCV(alphas=None, copy_X=True, cv='warn', eps=0.001, fit_intercept=True,
             l1_ratio=0.5, max_iter=1000, n_alphas=100, n_jobs=None,
             normalize=False, positive=False, precompute='auto',
             random_state=None, selection='cyclic', tol=0.0001, verbose=0). Check the list of available parameters with `estimator.get_params().keys()`.

Hope that helps,
