Cause Analysis

The MindSpore graph fails to be built, possibly due to outdated build data being loaded from the cache after model parameter modifications.

Solution

• (Recommended) Method 1: Delete the files in the graph build cache path specified by MS_COMPILER_CACHE_PATH.
• Method 2: Modify the training startup script to disable graph build cache.
