I succesfully installed django_raster with pip Then I add 'raster' to installed_apps but starting server (django 1.9 on Ubuntu 14.04) I get the following exception:

in line 7, simply putting dot before utils resolvs: from .utils import convert_pixeltype, HEADER_STRUCTURE, HEADER_NAMES,

@enricofer thanks for reporting this. Unfortunately the last version available on pypi is out of date. The package has changed a lot since then. For instance, I included the ogrraster module into Django itself, see

https://docs.djangoproject.com/en/1.9/ref/contrib/gis/gdal/#raster-data-objects https://docs.djangoproject.com/en/1.9/ref/contrib/gis/model-api/#rasterfield https://docs.djangoproject.com/en/1.9/ref/contrib/gis/db-api/#creating-and-saving-models-with-raster-fields

So i would recommend to install directly from master until the next release

 pip install git+https://github.com/geodesign/django-raster.git@master

I use the master branch of the package in my project and it works fine, but I am still working towards a new release. I want to document things better before that.

Well, I will do that. Thanks.
