Benchmarking YOLOv8 on Seeed Studio reComputer J4012

We in contrast ML runtimes of various YOLOv8 fashions on the reComputer J4012 and the outcomes are summarized beneath. The fashions have been run on a check video and the latency metrics have been obtained for various mannequin codecs and enter shapes. Curiously, PyTorch mannequin runtimes didn’t change a lot throughout totally different mannequin enter sizes whereas TensorRT confirmed marked enchancment in runtime with lowered enter form. The explanation for the shortage of modifications in PyTorch runtimes is as a result of the PyTorch mannequin doesn’t resize its enter shapes, however reasonably modifications the picture shapes to match the mannequin enter form, which is 640×640.

Relying on the enter sizes and sort of mannequin, TensorRT compiled fashions carried out higher over PyTorch fashions. PyTorch fashions appear to have a decreased efficiency in latency when mannequin enter form was decreased which is because of further padding. Whereas compiling to TensorRT, the mannequin enter is already thought-about which removes the padding and therefore they carry out higher with lowered enter form. The next desk summarizes the latency benchmarks (pre-processing, inference and post-processing) for various enter shapes utilizing PyTorch and TensorRT fashions working Detection and Segmentation. The outcomes present the runtime in milliseconds for various mannequin codecs and enter shapes. For outcomes on uncooked inference runtimes, please consult with the benchmark outcomes revealed in Seeed Studio’s weblog put up.
