optimization loss

[Yang-L1]

Hi,
Line 119 in train.py
train_op = optimizer.minimize(loss, global_step=batch)
Should this loss be loss[0]? Since the loss is a tuple object from the get_loss() function.

Btw, was the pretrained model trained by a huber loss or L2 loss?

loss is a scalar tensor. The pretrained model is trained under L2 loss.
