Module Contents

airpack_scripts.tf2.run_inference.get_file_pars(filename)

File names are of the format: key0=val0_key1=val1_key2=val2.bin so that we can easily parse the file name to get the file parameters, e.g., snr=10. This will allow us to only plot the desired SNR values.

Parameters

filename (Union[get_file_pars.str, os.PathLike]) – filename string to parse

Returns

Dictionary of file parameters

Return type

Dict[get_file_pars.str, Any]

airpack_scripts.tf2.run_inference.setup_inference_function(saver_path, file_name='saved_model.onnx')

Sets up a tensorflow session from an onnx file to perform inference

Parameters

• saver_path (pathlib.Path) – Path to onnx file

• file_name (str) – onnx file name

Returns

Callable inference function

Return type

Callable[[numpy.ndarray], List[float]]

airpack_scripts.tf2.run_inference.infer(data_folder, plot_snr=12, fs=31250000.0)

This script will re-initialize a trained TensorFlow model for inference. It will look through the test_data_folder and find one signal file for each label and for the SNR value defined by plot_snr.

Note

For the provided data set, plot_snr may range from -5 to 20 dB and the accuracy of the trained model may be shown to go down as the SNR is decreased.

Parameters

• data_folder (Union[str, os.PathLike]) – Location of data

• plot_snr (int) – Define desired SNR to plot

• fs (float) – Define sample rate

Returns

Inference results

Return type

List[float]
