Index out of Bounds Error for Session-Aware Recommendation (Opt and Single Mode)

Using a config file based off of the example_session_aware_opt.yml. This error persists with many different models, but I am currently working with hgru4rec.py.

My data set is labeled with the default headers of [SessionId, ItemId, Time, UserId], and I have ensured there are no new new items or users in the valid/test set.

Any help would be appreciated.

  params: {
    n_epochs: 1, 
    session_layers: 10,
    user_layers: 10,
    loss: 'top1'
  }
