environment.yml / requirements.txt missing?

[jf---]

Perhaps an idea to be explicit which dependency versions are expected / to provide a environment.yml for the repo?

Probably going overboard, but PyCharm has pretty nice interface which shows what is the latest version nr for a particular dependency, and conda & pip dont bite

dependencies:
  - python=3.6
  - lxml>=4.2 # redundant, see xml
  - numpy=1.14.0 # 1.15 gives issues
  - yarn
  - pip
  - pip:
    - -r file:requirements.txt # warm fuzzy version completion in IDE
