Question on Model Registry for models trained outside GCP

[sureshAZ]

Hello,

I have used Google Colab to fine tune a model and wanted to serve from Google Cloud. So, I copied the model to GCS and imported into model registry. I tried to deploy to an endpoint. But the deployment was not successful with the following error message (Invalid Image Error). 

I have used to models from Hugging Face to fine tune my model. Questions are 1) How do we fix this error? 2) Does ML registry / ML deployment in GCP support model trained/tuned outside GCP? 

Thank you for your resolution/suggestions/comments. Happy Thanksgiving.
