title: Use coo_matrix in TensorFlow
body: <p>I'm doing a Matrix Factorization in TensorFlow, I want to use coo_matrix from Spicy.sparse cause it uses less memory and it makes it easy to put all my data into my matrix for training data.</p>
  
  <p>Is it possible to use coo_matrix to initialize a variable in tensorflow?</p>
  
  <p>Or do I have to create a session and feed the data I got into tensorflow using sess.run() with feed_dict.</p>
  
  <p>I hope that you understand my question and my problem otherwise comment and i will try to fix it.</p>
