create_mask¶
- pytorch_forecasting.utils.create_mask(size: int, lengths: torch.LongTensor, inverse: bool = False) torch.BoolTensor[source]¶
Create boolean masks of shape len(lenghts) x size.
An entry at (i, j) is True if lengths[i] > j.
- Parameters
size (int) – size of second dimension
lengths (torch.LongTensor) – tensor of lengths
inverse (bool, optional) – If true, boolean mask is inverted. Defaults to False.
- Returns
mask
- Return type
torch.BoolTensor
