DoublePrecisionPlugin

class pytorch_lightning.plugins.precision.DoublePrecisionPlugin[source]

Bases: pytorch_lightning.plugins.precision.precision_plugin.PrecisionPlugin

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

connect(model, optimizers, lr_schedulers)[source]

Converts the model to double precision and wraps it in a LightningDoublePrecisionModule to convert incoming floating point data to double (torch.float64) precision. Does not alter optimizers or lr_schedulers.
