Utilities related to memory.

pytorch_lightning.utilities.memory.garbage_collection_cuda()

Garbage collection Torch (CUDA) memory.

Return type:

None

pytorch_lightning.utilities.memory.get_model_size_mb(model)

Calculates the size of a Module in megabytes.

The computation includes everything in the state_dict(), i.e., by default the parameters and buffers.

Return type:

float

Returns:

Number of megabytes in the parameters of the input module.

pytorch_lightning.utilities.memory.recursive_detach(in_dict, to_cpu=False)

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
