Class

SymbolicFloat32Array

Typed array used for input and output variables of DescriptorRunner. You can use SymbolicFloat32Array almost as same as Float32Array.

To convert SymbolicFloat32Array into actual Float32Array, use toActual()


let result = runner.outputs[0];  //runner.outputs is array of SymbolicFloat32Array

// SymbolicFloat32Array does NOT support index access
console.log(result[0]);
>>> undefined

// By conversion, you can access each element by index
console.log(result.toActual()[0]);
>>> 1.00  // Actual result
