Detailed Description

The NeonBackendModelContext is used to pass in Neon specific backend ModelOptions.

The supported backend ModelOptions are:

  • "FastMathEnabled"
    Using the fast_math flag can lead to performance improvements in fp32 and fp16 layers but may result in
    results with reduced or different precision. The fast_math flag will not have any effect on int8 performance.
  • "NumberOfThreads"
    Specify the number of threads used by the CpuAcc backend.
