No acc and rmse for IntensityFree

[yuzhenmao]

Hi, Thank you for the amazing work! When I run python train_nhp.py --experiment_id IntensityFree_train, I found it only printed out loglike and num_events, like this:

INFO: [ Epoch 450 (train) ]: train loglike is 0.345095773208137, num_events is 27590 INFO: [ Epoch 450 (valid) ]: valid loglike is 0.3291581182213554, num_events is 40073 INFO: [ Epoch 450 (test) ]: test loglike is 0.323051981051905, num_events is 82197

Would it be possible to also print out the ACC and RMSE metrics for the IntensityFree model? I assume it is feasible, as both metrics are reported in Table 1 of the original paper.

Thanks!
