DoublePrecision¶
- class lightning.fabric.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:
- 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:
- convert_output(data)[source]¶
Convert outputs to the floating point precision type expected after model’s forward.
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:
- forward_context()[source]¶
A contextmanager for managing model forward/training_step/evaluation_step/predict_step.
- Return type:
- 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:
