Please describe your issue below:

Good evening! I’m trying to run my own model on vim3, I already converted my yolov5.onnx into yolov5.tmfile and it works fine with CPU. Then I decided to quantize my weights to use them on TIM-VX model (I found the mean and std of my dataset and put them in). But the TIM-VX model gives no predictions in this situatuon :frowning:
Therefore I have few questions: I saw you have yolov3_uint8 and yolov4_timvx - what are the differences? When I decided to quantize the model, I saw in the example this:
Why Mean is float number which is bigger then 1? I’m using this mean parametres -
mean = (0.5691, 0.6521, 0.6264), std = (0.2409, 0.2492, 0.2994) which I calculated using usual algorithm. Maybe I’m doing it wrong and your model needs different parametres.
I wish you will be able to help me!

Post a console log of your issue below:

The TIM-VX program just doesnt give any predictions, how ever CPU version gives
