<div>I am wondering if it's possible to get the
weight coefficients of logistic regression
from a pipeline?</div>
<div><br>
</div>
<div>For instance, I have the followings:</div>
<div>

pipe_lr = Pipeline([['sc',
StandardScaler()], ['clf', clf_lr]])<br>
pipe_lr.fit(X, y)</blockquote>
</div>
<div><br>
</div>
<div>Does pipe_lr have an attribute that I can
call to get the weight coefficient?</div>
<div><br>
</div>
<div>Or do I have to get it from the classifier
as follows?</div>
<blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">X_std =
StandardScaler().fit_transform<wbr>(X)<br>
clf_lr = LogisticRegression(penalty='l1<wbr>',
C=0.1)<br>
clf_lr.fit(X_std, y)<br>
