Code on Ml-20m can't achieve the same performance as in paper

[outside-BUPT]

my result:
hit@1:0.2399， ndcg@5:0.393, hit@5:0.536, ndcg@10:0.4379=, hit@10:0.6718, ap:0.3794

result from paper:

@outside-BUPT how many steps did you train the model?

[oscarriddle]

I tried to run run_ml-1m.sh and also got bad evaluation performance as below.
I noticed the script sets train steps to 400000.

@oscarriddle The default number of training steps in this script needs to be higher to reproduce the reported result.
If you want to get closer to the reported results, you'll have to increase the number of steps by a factor of 20 (e. g. 8M or even more), but the training will take a lot of time.

After training about 35,000,000 steps, still wandering around a rather low saddle point, merely above SASrec's performance mentioned in paper.
