--------------------------------------

Hi [~Yisen], this should be resolved for the latest `v0.1.0` release at `master`.

> While attempting to run the example TfVgg16 script located in [examples/models/image_classification/|http://examples/models/image_classification/,],
I encountered this error after the training and evaluation steps:
> {{OperationalError: out of memory}}{{DETAIL: }}{{Cannot enlarge string buffer containing
0 bytes by 1076732998 more bytes.}}
>  
> It seemed to arise from the PostgreSQL database when the client tried to send in a query
larger than 1gb (1076732998 bytes in the screenshot). I am not exactly how to resolve this.
Previously, there were also other dimensional input errors but I modified the scripts slightly
with additional reshape functions so the training can proceed.
