keras: R Interface to 'Keras'

Interface to 'Keras' <https://keras.io>, a high-level neural networks 'API'. 'Keras' was developed with a focus on enabling fast experimentation, supports both convolution based networks and recurrent networks (as well as combinations of the two), and runs seamlessly on both 'CPU' and 'GPU' devices.

Version: 2.16.0
Depends: R (≥ 3.6)
Imports: generics (≥ 0.0.1), reticulate (≥ 1.31), tensorflow (≥ 2.13.0.9000), tfruns (≥ 1.0), magrittr, zeallot, glue, methods, R6, rlang
Suggests: ggplot2, testthat (≥ 2.1.0), knitr, rmarkdown, callr, tfdatasets, withr, png, jpeg
