anijain2305 commented on issue #4828: [QNN][TFLite] TFLite rounding mode support URL: https://github.com/apache/incubator-tvm/pull/4828#issuecomment-583275379 I thought little more about the bit exact problem. One source of discrepancy for certain is QNN add, and QNN concatenate ops. These call Requantize internally, and they will have default rounding in C++ (UPWARD). For testing, @LiangHao151941 , you can set the C++ default to TFLIte to see if it helps. Meanwhile, we can also think how to can make that C++ rounding visible at python level.
