ValueError: swagger.yaml is not a valid swagger2.0 file: expected string or buffer

I'm trying to parse a swagger file:

from swagger_parser import SwaggerParser
p = SwaggerParser(swagger_path='swagger.yaml')

The same file is valid in editor.swagger.io and http://bigstickcarpet.com/swagger-parser/www/index.html

I'd like at least a line number or similar to better understand the error.

I have the same issue. Even with minimal swagger, such as:

swagger: "2.0"
info:
  description: "This is a sample server Petstore server."
  version: "1.0.0"
  title: "Swagger Petstore"
schemes:
- "http"
paths:
  /pet:
    post:
      operationId: "addPet"
      parameters:
      - in: "body"
        name: "body"
        required: true
        schema:
          $ref: "#/definitions/Pet"
      responses:
        201:
          description: "Created"
        400:
          description: "Bad request"

definitions:
  Pet:
    type: "object"
    required:
    - "name"
    properties:
      id:
        type: "integer"
      name:
        type: "string"
        example: "doggie"

Issue remains with version 1.0.1, JSON converted swagger files work fine though.

I am having the same error when parsing a yaml file.

I was able to track the problem down to python's re module and it is having problems with the yaml similar to the following

        201:
          description: "Created"
        400:
          description: "Bad request"

values 201 and 400 above are parsed as integers and therefore re complains about the type of the value being inserted.
Yaml below will work perfectly with the lib

        "201":
          description: "Created"
        "400":
          description: "Bad request"

I can make a pr
