Parse Configuration Flags for a TensorFlow Application
Description
Parse configuration flags for a TensorFlow application. Use this to parse and unify the configuration(s) specified through a flags.yml
configuration file, alongside other arguments set through the command line.
Usage
parse_flags(
config = Sys.getenv("R_CONFIG_ACTIVE", unset = "default"),
file = "flags.yml",
arguments = commandArgs(TRUE)
)
Arguments
Arguments | Description |
---|---|
config | The configuration to use. Defaults to the active configuration for the current environment (as specified by the R_CONFIG_ACTIVE environment variable), or default when unset. |
file | The configuration file to read. |
arguments | The command line arguments (as a character vector) to be parsed. |
Value
A named R
list, mapping configuration keys to values.
