cuda_amp_grad_scaler: Creates a gradient scaler

In torch: Tensors and Neural Networks with 'GPU' Acceleration

Creates a gradient scaler

Description

A gradient scaler instance is used to perform dynamic gradient scaling to avoid gradient underflow when training with mixed precision.

Usage

cuda_amp_grad_scaler(
  init_scale = 2^16,
  growth_factor = 2,
  backoff_factor = 0.5,
  growth_interval = 2000,
  enabled = TRUE
)

Arguments

init_scale	a numeric value indicating the initial scale factor.
growth_factor	a numeric value indicating the growth factor.
backoff_factor	a numeric value indicating the backoff factor.
growth_interval	a numeric value indicating the growth interval.
enabled	a logical value indicating whether the gradient scaler should be enabled.

Value

A gradient scaler object.
