Issue with INT ENUM types while generating for python

Hi,

I'm using Swagger Codegen OS 3.0.59.

I have issues with all ENUM of type integer:

Error:

NameError: name 'CpuEnum' is not defined

Declaration in the Swagger spec file:

"cpu": {
            "type": "integer",
            "default": 1,
            "description": "The number of **virtual CPU** of the nodes of the cluster.",
            "enum": [
              1,
              2,
              4,
              6,
              8,
              12,
              16
            ],
            "example": 4,
            "nullable": false
          }

It seems a bug to me and I saw related bugs since 2014. Can you advice me on how to handle this?

Thank you.
