FileNotFoundError: [Errno 2] No such file or directory: '<dir_path>/pattern/text/en/en-model.slp'

I have also tried with pip3 as well as python3 setup.py install.
No luck on any of this.

Reproduce the failure with Python 3.5.2, PyInstaller 3.4, and pattern 3.6, then inspect pattern/text/en/init.py and pattern/text/init.py where en-model.slp is loaded. Confirm how the executable handles this resource; done means importing pattern.text.en from the packaged executable finds en-model.slp without FileNotFoundError.
