Butcher axe methods for kerasnip_model_fit

Description

These methods allow butcher::butcher() to reduce the memory footprint of fitted kerasnip model objects. The Keras model itself (stored as raw bytes in ⁠$fit$keras_bytes⁠) is always preserved so that predict() continues to work after butchering.

The main saving comes from axe_data(), which removes the training history object (⁠$fit$history⁠). For long training runs this can be several MB.

Usage

## S3 method for class 'kerasnip_model_fit'
axe_data(x, verbose = FALSE, ...)

## S3 method for class 'kerasnip_model_fit'
axe_env(x, verbose = FALSE, ...)

## S3 method for class 'kerasnip_model_fit'
axe_call(x, verbose = FALSE, ...)

## S3 method for class 'kerasnip_model_fit'
axe_ctrl(x, verbose = FALSE, ...)

## S3 method for class 'kerasnip_model_fit'
axe_fitted(x, verbose = FALSE, ...)

Arguments

x	A kerasnip_model_fit object.
verbose	Logical. Print information about memory released and disabled functions. Default is FALSE.
...	Not used.

Value

An axed kerasnip_model_fit object with the butcher_kerasnip_model_fit class prepended.
