E20007: Failed to run graph fusion pass [NonMaxSuppressionV6Fusion]. The pass type is [built-in-ai-core-graph-pass] 

        Solution: 1. If the pass code is custom, check the error log and the verification logic.  2. If the pass code is not custom, perform a complete or partial dump by using npucollect.sh and then send the dump to Huawei technical support for fault locating.
