AttributeError: 'numpy.ndarray' object has no attribute 'fit' when calling fit_transform on a pipeline

around this issue I'm getting the below error when I call pipeline.fit_transform(X_train, y_train). , You forgot to put self in the first init of preprocess
code :
class preprocess(TransformerMixin, BaseEstimator):

    def __init__(self):
        self.X = None
nb_pipeline = [('preprocess', preprocess()),
                    ('fit_NB', apply_NB())]

this one helps. This is the data i use count vectorizer and tfidftransformer and also use GaussianNB but i get error in this code. Please let me know the correct syntax. , Do
code :
clf = GaussianNB().fit(text_train_tfidf.toarray() , list(zip(*train))[1])
text_clf = text_clf.fit(list(zip(*train))[0] , list(zip(*train))[1])

fixed the issue. Will look into that further Unfortunately, you have mixed two different installation systems. You need to clear everything that was installed when you did pip3 install tensorflow.
The easiest is to start from scratch, and only do conda install tensorflow.

code :
>>> np.where(outlier_preds == -1)
(array([ 35,  59, 117, 118, 119, 126, 128, 141, 143, 144, 145, 146, 149,
        150, 151, 152, 153, 155, 156, 162, 175, 176, 184, 192, 201, 202,
        203, 204, 205, 214, 217, 218], dtype=int64),)
>>> np.where(outlier_preds == -1)[0][0] #First element only
