Are there something wrong with readme?

[Shawn9257]

Firstly, the code here with argement.py not config.py Secondly, the train parameter with load model doesn't get true or false. Also, the code here isn't accept (0,1,2,3) for Cuda device. (same as [0,1,2,3])

[alexfrom0815]

Thanks for the feedback!

1. config.py is aborted now, we only use arguments.py now
2. I can't figure out this question, can you explain it?
3. I run 'python main.py --device 0' in my laptop, and it succeed

Is --load-model here is used without True/False？

However in readme page ：

Example: Train a new model on sequences generated randomly.
You can run 'python main.py --mode train --load-model False --use-cuda --item-seq rs'.
It will take about one day to get a model with satisfying performance.

You can run 'python main.py --help' for some information of common parameters.
There are many other parameters of our project in 'config.py', and all of them are given default values. You can change it if you like.

For Question3:

This may be a misunderstanding on my part, I try to use multiple GPU in code that is not distributed. I try to use more than one device when I try to run the train in a bigger container_size.

For quesiton2 ： Thanks for pointing out this, there needs no parameter after --load-model. Just use 'python main.py' to train from scratch or use 'python main.py --load-model' to choose a pretrained model. For Question3: That's true, we have not added multiple GPU training since we believe only adding GPU cannot solve such an NP-hard problem. So we recommend PCT https://github.com/alexfrom0815/Online-3D-BPP-PCT, this can solve packing with larger scale
