<p>The supported backend ModelOptions are:</p><ul>
<li>"FastMathEnabled"<br />
Using the fast_math flag can lead to performance improvements in fp32 and fp16 layers but may result in<br />
results with reduced or different precision. The fast_math flag will not have any effect on int8 performance.</li>
<li>"NumberOfThreads"<br />
Specify the number of threads used by the CpuAcc backend. </li>
