Quick Fix

The quick fix for me was to add this line export PYTHONPATH=$PYTHONPATH:$(pwd) in the .travis.yml:

before_install:
  - "pip install -U pip"
  - "export PYTHONPATH=$PYTHONPATH:$(pwd)"

Have a setup.py

Having a setup.py which should be the default option as it is the most elegant. With that you would resolve your relative import issue, try one configured like:

from setuptools import setup, find_packages

setup(name='MyPythonProject',
      version='0.0.1',
      description='What it does',
      author='',
      author_email='',
      url='',
      packages=find_packages(),
     )

And then add this line in .travis.yml

before_install:
  - "pip install -U pip"
  - "python setup.py install
