hi，in demo.py why I test inference speed only 6 fps with titan xp？

Could you please check your tensorflow version? Maybe you are using tensorflow instead of tensorflow-gpu, that is, you are not using gpu to accelerate.

Thank you chick. Now I have another question. How can i realize real-time detection with my computer camera ? Because i coud not found the code for real-time detection by calling camera. Thankx!

You can follow the instruction in demo.ipynb, and change cv2.imread into opencv VideoCapture to get input frames, something like this:

cap = cv2.VideoCapture(0)

while(True):
    # Capture frame-by-frame
    ret, frame = cap.read()

    # predict output
    output = net.predict(frame)

    cv2.imshow('frame', output)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
