@gbelair That’s good, you got something functional. To troubleshoot the accuracy, I advise you to decrease the compression level to 0 by modifying the alls file. This will make sure all the layers are compressed to 8-bits, not 4-bits. Your fps might drop but you’ll see the accuracy with all the layers quantized to 8-bits. If accuracy is not good at that point, I’ll advice you to apply the quantization optimization methods mentioned here: Accuracy degradation after quantization for Hailo HW
