In the model inference code file customize_service.py, add a child model class. This child model class inherits properties from its parent model class. For details about the import statements of different types of parent model classes, see Table 1. The Python packages related to import statement...
This is also true for comments. Avoid using multiple statements to describe your code, and try to merge comments that explain the same code into a single comment. However, it’s important to be careful when you’re merging comments: careless merging of multiple comments can result in a huge...
