Best practice to update interactions with an existing dataset

[gabarlacchi]

Hi there! Thanks for the nice work in RecBole!

I'm implementing a simulation system in which I generate interactions between users and items within an existing system. At the start I create the dataset from a pre-loaded environment and define everything for recbole system. Everything's fine.
During the experiment, I would like to fully update the interactions that the system produce. I didn't find any useful functions to easy do such operation.

I missed something or can be a future update of the system?

So far, I just re-init the whole system by appending the new interactions to the .inter file, and run again the model and dataset configuration. There's a better way to do that?

Thanks!

Hello! Thanks for your attention.
You can use interaction.update to append new interactions.

RecBole/recbole/data/interaction.py

Line 273 in 68ef746

def update(self, new_inter):

This ''update'' function can not update other field in the Interaction automatically. For example:
The batch_size of interaction: 1
user_id, torch.Size([1]), cpu, torch.int64
item_id, torch.Size([1]), cpu, torch.int64
timestamp, torch.Size([1]), cpu, torch.float32
item_length, torch.Size([1]), cpu, torch.int64
item_id_list, torch.Size([1, 50]), cpu, torch.int64
timestamp_list, torch.Size([1, 50]), cpu, torch.float32
