Docker build fails

[lukesdm]

Executing ./docker.sh /path/to/dataset fails whilst trying to build the Docker image.

This appears to be due to a dependency version issue.

The syntax error is caused by the package using a Python 3.6 feature whilst only Python 3.5 is installed.

thanks for letting us know.

hmmm, okay. maybe we have to bump the Ubuntu version of the docker container; or omit the pip install -U pip to avoid this.

have to look into this.
