◆ npy_load()

visp::cnpy::NpyArray visp::cnpy::npy_load ( std::string fname )

Load the specified npy fname filepath as one array of data. This function is similar to the numpy.load function.

Parameters

[in] fname : Path to the npy file.

Returns: An array of basic data type.

Warning: This function has only been tested on little endian platform.

template<typename T >

void visp::cnpy::npy_save	(	std::string	fname,
		const std::vector< T >	data,
		std::string	mode = `"w"`
	)

Save the specified 1-D array of data (data) into the fname npz file. This function is similar to the numpy.save function.

Parameters

[in]	fname	: Path to the npy file.
[in]	data	: Pointer to a 1-D array of basic datatype (int, float, double, std::complex<double>, ...).
[in]	mode	: Writing mode, i.e. overwrite (w) or append (a) to the file.

Warning: This function has only been tested on little endian platform.

◆ npy_save() [2/2]

template<typename T >

void visp::cnpy::npy_save	(	std::string	fname,
		const T *	data,
		const std::vector< size_t >	shape,
		std::string	mode = `"w"`
	)

Save an array of data (data) into the fname npy file. This function is similar to the numpy.save function.

Parameters

[in]	fname	: Path to the npy file.
[in]	data	: Pointer to an array of basic datatype (int, float, double, std::complex<double>, ...).
[in]	shape	: Shape of the array, e.g. Nz x Ny x Nx.
[in]	mode	: Writing mode, i.e. overwrite (w) or append (a) to the file.

◆ npz_load() [1/2]

visp::cnpy::npz_t visp::cnpy::npz_load ( std::string fname )

Load the specified fname filepath as arrays of data. This function is similar to the numpy.load function.

Parameters

[in] fname : Path to the npz file.

Returns: A map of arrays data. The key represents the variable name, the value is an array of basic data type.

Warning: This function has only been tested on little endian platform.

Note: Original library: cnpy with MIT license.

◆ npz_load() [2/2]

visp::cnpy::NpyArray visp::cnpy::npz_load	(	std::string	fname,
		std::string	varname
	)

Load the specified varname array of data from the fname npz file. This function is similar to the numpy.load function.

Parameters

[in]	fname	: Path to the npz file.
[in]	varname	: Identifier for the requested array of data.

Returns: An array of basic data type.

Warning: This function has only been tested on little endian platform.

Note: Original library: cnpy with MIT license.
