Parameters
| Parameter | Type | Description |
|---|---|---|
| option | int | A member of the FifoOption enumeration that specifies which option value to set. |

Notes
- All Fifo options must be set before calling Fifo.allocate(). The FifoState must be CREATED.
- Using Graph.allocate_with_fifos() to create and allocate Fifos does not allow for any Fifo options to be set other than those specified in that function’s parameters.
Example
from mvnc import mvncapi
# Initialize a Fifo
fifo = mvncapi.Fifo('', mvncapi.FifoType.HOST_RW)
# Set the Fifo data type to FP16
fifo.set_option(mvncapi.FifoOption.RW_DATA_TYPE, mvncapi.FifoDataType.FP16)
# Destroy the Fifo
fifo.destroy()
