	Output (const dynet::ParameterMap &params, Construct &construct)
	Sets up the output to only record during certain timeperiods. Allows the usage of should_process.

	Output ()
	Creates an output that does not depend on time. Output::should_process should not be called when using this constructor.

bool	should_process (int t)
	Given the current time index, returns true if the current time period is flagged to be processed.

virtual	~Output ()
	Virtual Deconstructor. More...

virtual std::vector< int >	get_output_timeperiods (const dynet::ParameterMap &params, Construct &construct)
	Creates a vector of indexes that indicate in which timeperiod output should be processed. The parameter "timeperiods" in params controls this value. "all" will fill the entire the array with -1 followed by all timeperiods. "last" will set it to only contain the last time index. "initial" will set it to only contain -1. If it is none of these, the param is tokenized with a comma delimiter and converts the tokens to integers. Returned vector should always be ordered.

Detailed Description

Outputs the contents of a graph to a csv file.

Constructor & Destructor Documentation

◆ Output_Graph()

Output_Graph::Output_Graph	(	const dynet::ParameterMap &	params,
		Construct &	construct
	)

inline

Constructor for the "csv" type output.

Exception Safety

If parameters "network name", "output file", or "timeperiods" are not in the ParameterMap, a dynet::could_not_find_parameter is thrown. If the "output file" parameter does not have extension ".csv", a dynet::wrong_file_extension is thrown. If this file can not be opened for writing, a dynet::could_not_open_file is thrown. If the value for parameter "timeperiods" is not "last", "all", or "initial", a dynet::unknown_value is thrown.

Here is the call graph for this function:
