initializer_blockwise(initializers, sizes, validate_args = FALSE)list of Keras initializers, eg: keras::initializer_glorot_uniform()
or initializer_constant().
list of integers scalars representing the number of elements associated
with each initializer in initializers.
bool indicating we should do (possibly expensive) graph-time assertions, if necessary.
