Precautions for Operator Development

Precautions for Developing Custom Operators for an SSD Network with the Post-Processing Node

The PriorBox operator and detection output operator of the SSD network are automatically integrated during model conversion. If the implementation of the PriorBox operator of the SSD network has been customized, model conversion will fail due to the integration failure. In this situation, you need to delete the detection output operator from the network model file, and customize a post-processing node in engine orchestration to implement the function of the detection output operator.

Others

• Do not modify the implementation of the built-in operators of the framework (all files are saved in ddk/include/inc/custom). Otherwise, exceptions may occur. For example, the system fails to be started or the model cannot be converted.
• When developing an operator plug-in, customers shall be responsible for the source code to avoid backdoor implantation.
