DoublePrecision — PyTorch Lightning 2.5.1.post0 documentation (original) (raw)

class lightning.pytorch.plugins.precision.DoublePrecision[source]¶

Bases: Precision

Plugin for training with double (torch.float64) precision.

convert_input(data)[source]¶

Convert model inputs (forward) to the floating point precision type of this plugin.

This is a no-op in the base precision plugin, since we assume the data already has the desired type (default is torch.float32).

Return type:

Any

convert_module(module)[source]¶

Convert the module parameters to the precision type this plugin handles.

This is optional and depends on the precision limitations during optimization.

Return type:

Module

forward_context()[source]¶

A context manager to change the default tensor type.

See: torch.set_default_dtype()

Return type:

Generator[None, None, None]

module_init_context()[source]¶

Instantiate module parameters or tensors in the precision type this plugin handles.

This is optional and depends on the precision limitations during optimization.

Return type:

AbstractContextManager

tensor_init_context()[source]¶

Controls how tensors get created (device, dtype).

Return type:

AbstractContextManager
