TensorDictBase.sorted_keys#

property TensorDictBase.sorted_keys: list[NestedKey]#

The top-level keys of the tensordict, as a list sorted in alphabetical order.

For nested keys, call keys(include_nested=True, sort=True). On a locked tensordict, the sorted keys are cached until the tensordict is unlocked.

Examples

>>> from tensordict import TensorDict
>>> td = TensorDict(b=0, a=1, c=TensorDict(d=2))
>>> td.sorted_keys
['a', 'b', 'c']

Every tensordict class and every tensorclass has this method. For the other methods, see Methods by task.
