I don’t think it requires my PR to run a network successfully. Fetching an Int8Tensor is more of a development convenience to check intermediate results.
I’m not familiar with Android. Also, ONNX screws me up so many times that I ended up coding a tool from scratch. So I’m afraid I won’t be much of a help.
However, if you are okay with putting up some error msgs, I might be able to help if I’ve seen them before.
