as_padded_tensor¶
- class torchrl.envs.llm.transforms.as_padded_tensor(list_of_tensordicts: list[tensordict.base.TensorDictBase], dim=0, stack_dim: int = 0)[source]¶
Stacks a list of tensordicts into a single tensordict with padded tensors.
- Parameters:
list_of_tensordicts (list[[TensorDictBase]]) – A list of tensordicts to stack.
dim (int, optional) – The dimension along which to pad. Defaults to 0.
stack_dim (int, optional) – The dimension along which to stack. Defaults to 0.
- Returns:
A tensordict with padded tensors.
- Return type:
TensorDictBase
