# Error Handling
This section will introduce the error information when an exception occurs, so as to help you better understand the Dynamic-to-Static error information.
When running the transformed static graph code, the internal can be divided into two steps: the dynamic graph code is transformed into the static graph code, and the static graph code is run. We will introduce the error reporting in these two steps.
