## Description 

The second version of the PubChem324k Dataset used in the paper: [MolCA: Molecular Graph-Language Modeling with Cross-Modal Projector and Uni-Modal Adapter](https://arxiv.org/abs/2310.12798)

## Load Example 

```python
import torch
from torch_geometric.data import InMemoryDataset


class PubChemDataset(InMemoryDataset):
    def __init__(self, path):
        super(PubChemDataset, self).__init__()
        self.data, self.slices = torch.load(path)
    
    def __getitem__(self, idx):
        return self.get(idx)

if __name__ == '__main__':
    dataset = PubChemDataset('./pretrain.pt')
    print(dataset[0])
```
