Executes the AI model using the given inputs and outputs the result of execution.
Returns
- Returns status of Execute API. Returns 0 on success.
Usage
Called after the session is opened to execute AI model.
DataBuffer[] input = new DataBuffer[1];
DataBuffer[] output = new DataBuffer[1];
DataBuffer dB = new DataBuffer();
dB.setDataType((byte) 0);
dB.setDataFormat((byte) 1);
int[] shape = new int[]{1, 224, 224, 3};
dB.setShape(shape);
dB.setDataSource((byte)2);
try {
SharedMemory sharedMemory = SharedMemory.create("data", indata.length * 4);
ByteBuffer bBuffer = sharedMemory.mapReadWrite();
byte[] bytes = DataBuffer.readFloatToBytes(indata);
bBuffer.put(bytes);
dB.setDataShared(sharedMemory);
} catch (ErrnoException e) {
e.printStackTrace();
}
input[0] = dB;
status = session.execute(input, output);
if (output != null && output.length > 0 ) {
if (output[0].getDataSource() == 0) {
float[] outputData = output[0].getDataOriginal();
