Requirements

The requirements are:

  • Linux (and probably any environment that supports Python virtualenv and bash)
  • virtualenv
  • Python-2.7.12 (running in an isolated vitualenv)
  • Redis
  • MySQL or mariadb [optional - required for Panorama]
  • A Graphite implementation sending data would help :)

requirements.txt

The requirements.txt file lists the required packages and the last verified as working version with Python-2.7 within a virtaulenv.

Recent changes in the pip environment

Note

If you use pip or virtualenv in any other context, please note the following and assess if and/or how it pertains to you environment

The new pip, setuptools, distribute and virtualenv methodology that the pypa community has adopted is in a bit of a state of flux in terms of the setuptools version and virtualenv implementation of making the --distribute and --setuptools legacy parameters has caused pip 8.1.1 and setuptools 20.9.0 and virtualenv 15.0.1 to complain if distribute is one of the requirements on packages that pip tries to install. However, it is needed for Mirage if you are trying to run/upgrade on Python-2.6

pandas

Updated: 20161120 - can no longer be supported as of Ionosphere (probably)

The PANDAS_VERSION variable was added to settings.py to handle backwards compatability with any instances of Skyline that are run older versions that perhaps cannot upgrade to a later version due to any mainstream packaging restrictions. This PANDAS_VERSION is required to run the applicable panda functions dependent on the version that is use.

  • pandas 0.17.0 deprecated the pandas.Series.iget in favour of .iloc[i] or .iat[i]
  • pandas 0.18.0 introduced a change in the Exponentially-weighted moving average function used in a number of algorithms
if PANDAS_VERSION < '0.18.0':
    expAverage = pandas.stats.moments.ewma(series, com=15)
else:
    expAverage = pandas.Series.ewm(series, ignore_na=False, min_periods=0, adjust=True, com=15).mean()

if PANDAS_VERSION < '0.17.0':
    return abs(series.iget(-1)) > 3 * stdDev
else:
    return abs(series.iat[-1]) > 3 * stdDev

Skyline should be able to run on pandas versions 0.12.0 - 0.18.0 (or later)

Python-2.6 - may work, but not supported

Skyline can still run on Python-2.6. However deploying Skyline on Python-2.6 requires jumping through some hoops. This is because of the dependencies and pip packages moving a lot. At some point some older pip package is not going to be available any longer and it will no longer be possible, unless you are packaging the pip packages into your own packages, e.g. with fpm or such.

Updated: 20161120 - can no longer be supported as of Ionosphere (probably)

RedHat family 6.x

If you are locked into mainstream versions of things and cannot run Skyline in an isolated virtualenv, but have to use the system Python and pip. The following pip installs and versions are known to working, with a caveat on the scipy needs to be installed via yum NOT pip and you need to do the following:

Updated: 20161120 - this information is now too old to be applicable really.

pip install numpy==1.8.0
yum install scipy
pip install --force-reinstall --ignore-installed numpy==1.8.0

Known working scipy rpm - scipy-0.7.2-8.el6.x86_64

pip packages (these are the requirements and their dependencies), it is possible that some of these pip packages will no longer exist or may not exist in the future, this is documented here for info ONLY.
