Overview

This error code indicates an MTE flow error, which is often reported on the copy_ub_to_gm or copy_gm_to_ub command instructions. The possible cause is that the atomic data overflows or the address is incorrect.

• Out memory overwriting. Common causes are as follows: The memory offset calculated by the operator under a specific shape is incorrect. The infershape deduction is incorrect. As a result, the memory used by the operator is inconsistent with the memory allocated by the GE, and the address transferred to the kernel function cannot be accessed.
• Data overflow, which causes the atomic error (most common one). This error is not caused by the current operator. Because most network structures are complex and forward check is difficult, you need to use the version with interrupt mask enabled to locate the operator that overflows or introduces inf/NAN data.
