LiangHao151941 commented on issue #4828: [QNN][TFLite] TFLite rounding mode support URL: https://github.com/apache/incubator-tvm/pull/4828#issuecomment-595191104 The problem is located and solved. The discrepancy comes from average pooling calculation when input is integral type. tflite does a UPWARD rounding after the division in avg_pool but current topi implementation of avg_pool does of FLOOR after the division. The fix is added and tested locally on cpu. Now the qnn tests in tflite test_forward has rtol and atol set to 0, which should meet the bit-exact exectution requirement. @FrozenGene @anijain2305 @tqchen @u99127 Please have another look, thanks!
