Utilities related to memory.

lightning.pytorch.utilities.memory.garbage_collection_cuda()[source]¶

Garbage collection Torch (CUDA) memory.

Return type:: None

lightning.pytorch.utilities.memory.recursive_detach(in_dict, to_cpu=False)[source]¶

Detach all tensors in in_dict.

May operate recursively if some of the values in in_dict are dictionaries which contain instances of Tensor. Other types in in_dict are not affected by this utility function.

Parameters:

in_dict¶ (Any) – Dictionary with tensors to detach
to_cpu¶ (bool) – Whether to move tensor to cpu

Returns:

Dictionary with detached tensors

Return type:

out_dict
