some new discoveries: after reset to version when mege yolo-v3-tiny from @huajsj [09c55fd1f3354d2280bb792a252590ac6bd68e58](https://github.com/apache/tvm/commit/09c55fd1f3354d2280bb792a252590ac6bd68e58). the detection task works! the inference times on pynq Z1 is reduced to 615.49ms from 4520ms on arm_cpu version. **As an strong infer , some changes in 'Relay' might lead to the error on latest version wrote in the bug above. could any 'good soul' offer some help ?** > Cannot find config for target=ext_dev -device=vta -keys=cpu -model=pynq_1x16_i8w8a32_15_15_18_17, workload=('conv2d_nchw_winograd.arm_cpu', A fallback configuration is used, which may bring great performance regression. > yolov3-tiny inference graph built in 14.41s! > Performed inference in 615.49ms (std = 0.02) for 1 samples > Average per sample inference time: 615.49ms ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
