(how) can you train a model twice (multiple times) in sklearn using fit.?
<p>Example : my data doesn't fit into memory can I do :</p>

<pre><code>model=my_model
for i in range(20)
       model.fit(X_i,Y_i)
</code></pre>

<p>This will delete the first 19 fit. and keep only the last one.
How can I avoid this? Can I retrain a model saved and loaded?
Thank you</p>
