rtdetr

Real-time object detection you can ship: PyTorch training, OpenVINO inference, 100% Apache-2.0 — code and pretrained weights alike.

Install

pip install rtdetr              # inference
pip install "rtdetr[train]"     # + training

Detect

from rtdetr import RTDETR

model = RTDETR("rtdetr-r18")          # COCO weights, downloaded on first use
r = model("bus.jpg", conf=0.5)[0]

r.boxes.xyxy, r.boxes.conf, r.boxes.cls   # plain numpy
r.names[int(r.boxes.cls[0])]              # "person"
r.plot(); r.save(); r.show()

Point it at an image, a folder, a glob, a video, an RTSP stream, a webcam index, or a numpy array. Long sources stream:

for r in model.predict(0, stream=True, show=True):   # webcam, q or Esc quits
    print(r.boxes.xyxyn)

model.track("clip.mp4")        # adds r.boxes.id

Train

model = RTDETR("rtdetr-r18")
model.train(data="data.yaml", epochs=100, imgsz=640, batch=8, device=0)
model.val(data="data.yaml").box.map50
model.export(format="openvino", half=True)     # IR + labels.txt

# data.yaml
path: /data/cans
train: images/train
val: images/val
names: {0: can, 1: bottle}

Command line

rtdetr predict model=rtdetr-r18 source=bus.jpg conf=0.5
rtdetr train   model=rtdetr-r18 data=data.yaml epochs=100
rtdetr val     model=best.pt data=data.yaml
rtdetr export  model=best.pt format=openvino half=true

A browser front end

platform/ is a small web app on top of this package — label images, queue training runs, watch the curve, download the weights and the IR:

pip install -r platform/requirements.txt
python platform/run.py          # http://127.0.0.1:8080
