First of all thanks a million for your response. However, I supposed that, for the first few epochs, loss is usually more than 2 or 3 (seen in different pages and …). That’s why I thought that way. Again,  epoch_loss was   0.071 for first. In epoch 9 I got this
`[42m 12s] Train Epoch: 9 [2500/4500 (56%)]	 Loss_sum(total): 2.06 loss(mean) 0.04125
[42m 28s] Train Epoch: 9 [2750/4500 (61%)]	 Loss_sum(total): 2.06 loss(mean) 0.04128
[42m 44s] Train Epoch: 9 [3000/4500 (67%)]	 Loss_sum(total): 2.06 loss(mean) 0.04121
begin validation ...

total_loss_eval2.040340803149674
 EVAl Epoch: 9 [500]	Loss: 0.04

Also, epoch_loss is 0.0409. Somehow, I’ve seen train loss should be lower than eval-loss, but this isn’t the case for me. If incorrect,  please rectify me.
