cupy.asnumpy

cupy.asnumpy(a, stream=None)

Returns an array on the host memory from an arbitrary source array.

Parameters:

• a – Arbitrary object that can be converted to numpy.ndarray.
• stream (cupy.cuda.Stream) – CUDA stream object. If it is specified, then the device-to-host copy runs asynchronously. Otherwise, the copy is synchronous. Note that if a is not a cupy.ndarray object, then this argument has no effect.

Returns:

Converted array on the host memory.

Return type:

numpy.ndarray
