"""Upload a model to ModelDB.
This function will upload the given model into the database with some variation. It may optionally generate a
branch of models (i.e. model family) with different optimization techniques. Besides, a benchmark will be
scheduled for each generated model, in order to gain profiling results for model selection strategies.
In the `no_generate` model(i.e. `no_generate` flag is set to be `True`), `architecture`, `framework`, `engine`
and `version` could be None. If any of the above arguments is `None`, all of them will be auto induced
from the origin_model path. An `ValueError` will be raised if the mata info cannot be induced.
TODO:
This function has a super comprehensive logic, need to be simplified.
Arguments:
model: Required inputs for register a model. All information is wrapped in such model.
convert (bool): Flag for generation of model family. Default to True.
profile (bool): Flag for profiling uploaded (including converted) models. Default to True.
