The trained model has very low accuracy

[ting3000]

I run the training with 1,000,000 iterations, then copied the caffemodel file to openpose/models/pose/body_25 to replace the pose_iter_584000.caffemodel file, then run ./build/examples/openpose/openpose.bin --video examples/media/video.avi The result is very poor and it hardly detects any body part. What did I do wrong? What is the right way to evaluate the trained model? Do I need iterate more training?

Thanks,
