del_thread_name() [3/3]

void Darknet::CfgAndState::del_thread_name

(

const std::thread::id &

tid

Delete the thread name from the map. Does nothing if this thread wasn't given a name.

get() [1/4]

Darknet::CfgAndState & Darknet::CfgAndState::get ( )

static

Get a reference to the singleton used by Darknet.

get() [2/4]

const Darknet::ArgsAndParms & Darknet::CfgAndState::get

(

const std::string &

arg

)

const

Get a CLI argument based on the name.

For example, if you call it with "thresh" you'd get the threshold argument with the default value of 0.24 or whatever the user typed on the CLI.

Here is the call graph for this function:

get() [3/4]

float Darknet::CfgAndState::get	(	const std::string &	arg,
		const float	f
	)		const

Get a float parameter. This provided default value will be used if this parameter does not exist.

Here is the call graph for this function:

get() [4/4]

int Darknet::CfgAndState::get	(	const std::string &	arg,
		const int	i
	)		const

Get an integer parameter. The provided default value will be used if this parameter does not exist.

get_float()

float Darknet::CfgAndState::get_float

(

const std::string &

arg

)

const

Get a float parameter. This must exist, otherwise darknet_fatal_error() is called.

Here is the call graph for this function:

get_int()

int Darknet::CfgAndState::get_int

(

const std::string &

arg

)

const

Get an integer parameter. This must exist, otherwise darknet_fatal_error() is called.

get_thread_name()

std::string Darknet::CfgAndState::get_thread_name

(

)

is_set()

bool Darknet::CfgAndState::is_set	(	const std::string &	arg,
		const bool	default_value = false
	)		const

Determine if the user specified the given option, or if unspecified then use the default value.

For example:

if (cfg.is_set("map"))
{
    // do something when the user specified -map
}

Here is the call graph for this function:

process_arguments()

Darknet::CfgAndState & Darknet::CfgAndState::process_arguments	(	int	argc,
		char **	argp
	)

Process argv[] from main() and store the results in argv and args.

Todo:

need to fix things like the function "map" and the optional training parameter "-map" which would trigger this code

Member Data Documentation

additional_arguments

VStr Darknet::CfgAndState::additional_arguments

Parameters that were unrecognized.

args

MArgsAndParms Darknet::CfgAndState::args

A map of all arguments starting with argv[1].

Note this only has the arguments the user specified, not a collection of "all" possible arguments.

See also

Darknet::get_all_possible_arguments()

argv

VStr Darknet::CfgAndState::argv

Every argument starting with argv[0], unmodified, and in the exact order they were specified.

cfg_filename

std::filesystem::path Darknet::CfgAndState::cfg_filename

colour_is_enabled

bool Darknet::CfgAndState::colour_is_enabled

Determines if ANSI colour output will be used with the console output. Default is true.

command

std::string Darknet::CfgAndState::command

data_filename

std::filesystem::path Darknet::CfgAndState::data_filename

filenames

VStr Darknet::CfgAndState::filenames

function

std::string Darknet::CfgAndState::function

gpu_index

int Darknet::CfgAndState::gpu_index

The index of the GPU to use. -1 means no GPU is selected.

is_shown

bool Darknet::CfgAndState::is_shown

When -dont_show has been set, this value will be set to false.

is_trace

bool Darknet::CfgAndState::is_trace

Whether Darknet was started with the --trace flag.

This will also enable is_verbose. Default is false.

See also

Darknet::set_trace()

darknet_set_trace()

is_verbose

is_verbose

bool Darknet::CfgAndState::is_verbose

Whether Darknet was started with the --verbose flag.

Default is false.

See also

Darknet::set_verbose()

darknet_set_verbose()

is_trace

must_immediately_exit

std::atomic<bool> Darknet::CfgAndState::must_immediately_exit

This bool gets set by darknet_fatal_error() when a thread terminates and Darknet must exit.

This causes training to finish early, and also prevents Darknet from logging any more (misleading) errors that happen on additional threads.

names_filename

std::filesystem::path Darknet::CfgAndState::names_filename

thread_names

std::map<std::thread::id, std::string> Darknet::CfgAndState::thread_names

Name the threads that we create in case we have to report an error.

thread_names_mutex

std::mutex Darknet::CfgAndState::thread_names_mutex

Name the threads that we create in case we have to report an error.

weights_filename

std::filesystem::path Darknet::CfgAndState::weights_filename
