DoublePrecision¶

class lightning_fabric.plugins.precision.DoublePrecision[source]¶

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 for tensors that are not of floating-point type or already have the desired type.

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.

forward_context()[source]¶

A context manager to change the default tensor type.
