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 under. The fashions had been run on a take a look at video and the latency metrics had 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 rationale for the dearth of adjustments in PyTorch runtimes is as a result of the PyTorch mannequin doesn’t resize its enter shapes, however moderately adjustments 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 printed in Seeed Studio’s weblog publish.
