> ASAP. Hi, Thank you for your work. Could you please share the weights on ImageNet? Thanks again.

First, Removing them manually will increase workload after auto generate. Second, It will affect the original order of fields.

How to achieve logical deleting by `deleted_at`? Thanks! For example, a user record's `deleted_at` was set. I hope `Product.find_or_fail(id)` will raise sqlalchemy_mixins.ModelNotFoundError.

It will work at tensorflow-gpu==2.1.0. ```shell pip install tensorflow-gpu==2.1.0 ```
