|
**Benchmark mode** is used to profile the speed and accuracy of various export formats for YOLOv8. The benchmarks |
|
provide information on the size of the exported format, its `mAP50-95` metrics (for object detection, segmentation and pose) |
|
or `accuracy_top5` metrics (for classification), and the inference time in milliseconds per image across various export |
|
formats like ONNX, OpenVINO, TensorRT and others. This information can help users choose the optimal export format for |
|
their specific use case based on their requirements for speed and accuracy. |
|
|
|
!!! tip "Tip" |
|
|
|
* Export to ONNX or OpenVINO for up to 3x CPU speedup. |
|
* Export to TensorRT for up to 5x GPU speedup. |
|
|
|
## Usage Examples |
|
|
|
Run YOLOv8n benchmarks on all supported export formats including ONNX, TensorRT etc. See Arguments section below for a |
|
full list of export arguments. |
|
|
|
!!! example "" |
|
|
|
=== "Python" |
|
|
|
```python |
|
from ultralytics.utils.benchmarks import benchmark |
|
|
|
# Benchmark on GPU |
|
benchmark(model='yolov8n.pt', data='coco8.yaml', imgsz=640, half=False, device=0) |
|
``` |
|
=== "CLI" |
|
|
|
```bash |
|
yolo benchmark model=yolov8n.pt data='coco8.yaml' imgsz=640 half=False device=0 |
|
``` |
|
|
|
## Arguments |
|
|
|
Arguments such as `model`, `data`, `imgsz`, `half`, `device`, and `verbose` provide users with the flexibility to fine-tune |
|
the benchmarks to their specific needs and compare the performance of different export formats with ease. |
|
|
|
| Key | Value | Description | |
|
|-----------|---------|-----------------------------------------------------------------------| |
|
| `model` | `None` | path to model file, i.e. yolov8n.pt, yolov8n.yaml | |
|
| `data` | `None` | path to yaml referencing the benchmarking dataset (under `val` label) | |
|
| `imgsz` | `640` | image size as scalar or (h, w) list, i.e. (640, 480) | |
|
| `half` | `False` | FP16 quantization | |
|
| `int8` | `False` | INT8 quantization | |
|
| `device` | `None` | device to run on, i.e. cuda device=0 or device=0,1,2,3 or device=cpu | |
|
| `verbose` | `False` | do not continue on error (bool), or val floor threshold (float) | |
|
|
|
