MI Hub¶

Issue Description	Discovered On	Resolved On
Due to the resource and permission restrictions of the underlying image repository, the amount of registered models and model versions is limited. Currently, at most 30 models can be registered, and at most 50 versions can be staged for a model. After reaching the limit, users need to contact the operation team to remove invalid models from the image repository. After release resources, users can register new models and stage new model versions.	2020/12/30
