Source: R/serialize.R
nv_unserialize.Rd

Deserializes arrays from the safetensors format.

Usage

nv_unserialize(con, device = NULL, backend = default_backend())

Arguments

con

(connection | raw)
A connection or raw vector to read from.

device

(NULL | character(1) | PJRTDevice)
The device on which to place the loaded arrays ("cpu", "cuda", ...). Default is to use the CPU.

backend

(character(1))
Backend for the loaded arrays. Defaults to default_backend().

Value

Named list of AnvlArray objects.

Details

The data type, shape, and ambiguity of each array are restored from the serialized data.
