Travis Itself Fails for some Unusual Reason

[ghost]

Travis is complaining about nearly every Pull Request, including #205

Here is the error message:

No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself. Check the details on how to adjust your build configuration on: https://docs.travis-ci.com/user/common-build-problems/#Build-times-out-because-no-output-was-received The build has been terminated

@markus-beuckelmann The issue may not be in the Python test scripts, but rather in the test set-up scripts.
