Problem Source Demarcation
- After finding the first operator whose input is similar but output is different, you can determine that the operator is faulty.
- If the operator is a fusion operator, the accuracy problem is caused by operator fusion. In this case, disable the fusion and perform accuracy comparison again to check whether other problems exist.
- If the input or output of the operator contains embedding variables and the embedding variables are different, the accuracy problem is caused by Rec SDK TensorFlow table lookup.
