Hi, this problem can be solved by just remove the line code.

print(json.dumps(config, indent=4), flush=True)

it doesn't make any difference to the result of the training. And do you have occurred the error about : ValueError: setting an array element with a sequence. in the code of bpr.model.py 、rnn.model.py、rnn_att.model.py :

def train(self, sess, uij, l):
113     loss, _ = sess.run([self.loss, self.train_op], feed_dict={
114         self.u: uij[0],
115         self.i: uij[1],
116         self.y: uij[2],
117         self.hist_i: uij[2],
118         self.sl: uij[4],
119         self.lr: l,
120         })
