loadnpy

Abstract

Load an array (of any number of dimensions) saved as a .npy file

Description

loadnpy loads an array saved as a .npy file. A .npy file holds a possibly multidimensional array of either int or float type, with members of 32 or 64 bits. This opcodes converts all such formats to a float array of the same shape. For more information on the .npy format, see https://numpy.org/devdocs/reference/generated/numpy.lib.format.html

Syntax

iArr[] loadnpy Spath
kArr[] loadnpy Spath

Arguments

• Spath: the path to the saved .npy file

Output

• iArr / kArr: the data as an array.

Execution Time

• Init
