NDArray::cpu

public function cpu(): NDArray;

Copy the NDArray to the CPU for computation. If the NDArray is already in RAM, a copy will still be made.

Return​

Type NDArray

  • A copy of the NDArray but stored in RAM.

Examples​

use \NDArray as nd;

$a_gpu = nd::array([2, -2,   3])->gpu();

$a_cpu = $a->cpu();

$a_gpu->dump();
$a_cpu->dump();
