Hello, I am trying to reproduce the [logP benchmark for GCPN](https://torchdrug.ai/docs/benchmark/generation.html): Coming close to a top-1 property score of 6.560 Penalized LogP. For this, I ran the same code provided in the [tutorial](https://torchdrug.ai/docs/tutorials/generation.html) multiple times. However, the highest Penalized LogP values I seem to achieve is ~ 2.7 which is way lower than the benchmark of 6.560. Did anyone manage to reproduce the benchmark? Thank you!
