[jira] [Created] (SINGA-414) TfVgg16 OperationalError for Rafiki

Ng Yi Sen created SINGA-414:
-------------------------------

             Summary: TfVgg16 OperationalError for Rafiki
                 Key: SINGA-414
                 URL: https://issues.apache.org/jira/browse/SINGA-414
             Project: Singa
          Issue Type: Bug
            Reporter: Ng Yi Sen
         Attachments: Screenshot 2018-11-29 at 4.55.45 PM.png

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.
