ImportError - Swagger codegen for flask

[ctippur]

Description

I am getting the following error when running flask server:
from .binary import Binary
File "/Users/ctippur/cyclops/cyclopscloud/flaskapi/cyclopsflaskglobal/python-flask-server/swagger_server/models/binary.py", line 4, in
from swagger_server.models.binary import Binary

Here is the tree for swagger server that got generated via swagger UI (http://editor.swagger.io)

Swagger-codegen version

I generated server code via http://editor.swagger.io

Swagger declaration file content or ur

Command line used for generation

N/A

Steps to reproduce

python3 -m venv flaskglobal
source flaskglobal/bin/activate
cp binary to flaskglobal and unzip contents
cd python-flask-server
pip install -r requirements.txt
python -m swagger_server

Could this be a pythonpath issue?

I am using python 3.62 on a mac.

I believe this maybe similar to #4789
