Hello Query Device Python* Sample
This topic demonstrates how to run the Hello Query Device sample application, which queries Inference Engine devices and prints their metrics and default configuration values. The sample shows how to use Query Device API feature.
How It Works
The sample queries all available Inference Engine devices and prints their supported metrics and plugin configuration parameters.
Running
The sample has no command-line parameters. To see the report, run the following command:
python3 hello_query_device.py
Sample Output
The application prints all available devices with their supported metrics and default values for configuration parameters. For example:
Available devices:
Device: CPU
Metrics:
AVAILABLE_DEVICES: 0
SUPPORTED_METRICS: AVAILABLE_DEVICES, SUPPORTED_METRICS, FULL_DEVICE_NAME, OPTIMIZATION_CAPABILITIES, SUPPORTED_CONFIG_KEYS, RANGE_FOR_ASYNC_INFER_REQUESTS, RANGE_FOR_STREAMS
FULL_DEVICE_NAME: Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz
OPTIMIZATION_CAPABILITIES: WINOGRAD, FP32, INT8, BIN
SUPPORTED_CONFIG_KEYS: CPU_BIND_THREAD, CPU_THREADS_NUM, CPU_THROUGHPUT_STREAMS, DUMP_EXEC_GRAPH_AS_DOT, DYN_BATCH_ENABLED, DYN_BATCH_LIMIT, EXCLUSIVE_ASYNC_REQUESTS, PERF_COUNT, RANGE_FOR_ASYNC_INFER_REQUESTS, RANGE_FOR_STREAMS
RANGE_FOR_ASYNC_INFER_REQUESTS: 0, 6, 1
RANGE_FOR_STREAMS: 1, 12
Default values for device configuration keys:
CPU_BIND_THREAD: YES
CPU_THREADS_NUM: 0
CPU_THROUGHPUT_STREAMS: 1
DUMP_EXEC_GRAPH_AS_DOT:
DYN_BATCH_ENABLED: NO
DYN_BATCH_LIMIT: 0
