Troubleshooting
We strongly encourage using conda to maintain the Python libraries on which RAVEN depends. Note that conda can be installed locally without administrative privileges on most systems. However, if conda is not available, the necessary libraries and versions can be obtained by the following call:
cd raven
python scripts/TestHarness/testers/RavenUtils.py --conda-installThis will print to terminal a command that includes a listing of all the libraries, some with specific tagged versions. These libraries may be installed through pip or other Python or OS package managers, after which RAVEN can be run.
If library versions other than the specific tagged versions are installed, RAVEN will exit when run and complain of improper libraries for the version of RAVEN you are trying to run.
If there are missing libraries, (for example if you get errors like ImportError: No module named sklearn) then the Installing RAVEN Libraries page should be used to try and fix the problem.
In the raven directory, the command:
./run_tests --library_report
can be used to see which libraries are being used and which are missing.
Older versions of the MOOSE redistributable package (From http://mooseframework.org/getting-started/osx/ ) contains everything needed to run RAVEN except the scikit-learn package for Python. If this package is missing, running the tests looks like this...

Fortunately, the redistributable includes the Miniconda package manager which can be used to install it.

If there are problems with distribution1D or interpolationND these are problems with the crow libraries. These can be built with make framework_modules in the raven directory.
If some of the data can not be retrieved from the internet (or git clone or update commands fail) possibly the proxy is not being used. See INL proxy
On some systems (for example Ubuntu 16 and Windows 7) the default backend for matplotlib is set to Qt5Agg, which may not be properly set up after installing libraries through conda. A simple fix is to change the default backend to something more generic, for example TkAgg.
The matplotlib defaults file for the raven_libraries conda environment is usually located in ~/miniconda2/envs/raven_libraries/lib/python2.7/site-packages/matplotlib/mpl-data/matplotlibrc. If not, the location can be discovered via the following python commands (from here):
>>> import matplotlib
>>> matplotlib.matplotlib_fname()
'/home/foo/.config/matplotlib/matplotlibrc'The keyword to change is "backend".
The problems using QT5Agg seem not to be present if matplotlib is updated to version 2.1.1 or later. RAVEN will likely move to this library version in a future update.
