title: Linear Regression with positive coefficients in Python
body: <p>I'm trying to find a way to fit a linear regression model with positive coefficients.</p>
  <p>The only way I found is <a href="http://scikit-learn.org/stable/modules/generated/sklearn.linear_model.Lasso.html" rel="nofollow noreferrer">sklearn's Lasso model</a>, which has a <code>positive=True</code> argument, but doesn't recommend using with alpha=0 (means no other constraints on the weights).</p>
  <p>Do you know of another model/method/way to do it?</p>
