Python Build Issues

Description

Attempting to create a python module for using the Royal Mail rest API.
Swagger output the module, and pip install . works fine.

Importing the newly created module results in

ImportError: No module named 'rm_tracking.models.inline_response200_error'

Which is because the path should be:
rm_tracking.models.inline_response_200_error

  title: Tracking API (REST)
  description: "Tracking API provides the functionality to enquire on the tracking
    status of mail items. The API provides the latest tracking information, the tracking
    history, and the proof of delivery information (minus the signature image) for
    a single mail item. The API provides an alternative mechanism to using the track
    and trace function on the Royal Mail website (http://www.royalmail.com/track-trace).
    \n \nThere are no costs to customers for using the Tracking API services, however
    development costs must be covered by the customer. Royal Mail will not accept
    any responsibility for these development, implementation and testing costs.\n
    \nCustomers should address initial inquiries regarding development of systems
    for these purposes to their account handler."

Config.json

{
  "packageName": "rm_tracking",
  "projectName": "rm-tracking-api"
}

Command line used for generation

swagger-codegen generate -i Tracking_Swagger.yaml -l python -c config.json -o swagger

this outputs to /swagger

Steps to reproduce

• create a new directory
• cd new_directory
• place Tracking_Swagger.yml file here
• place config.json here
• make a subdirectory called swagger
• swagger-codegen generate -i Tracking_Swagger.yaml -l python -c config.json -o swagger
• cd swagger
• pip3 install .

Then in python:

• import rm_tracked

This will fail due to incorrect path to InlineResponse200Error

Reproduce the failure using Tracking_Swagger.yaml, config.json, and the documented swagger-codegen command, then inspect the generated /swagger package and its rm_tracking.models imports. Compare the generated reference to the available InlineResponse200Error module path. Done means pip install . succeeds and importing the generated client no longer requests the incorrect inline_response200_error path.
