If you are using Ubuntu 14.04, there is a known bug in OpenJPEG that will prevent OpenSlide from reading certain files. This requires building OpenJPEG, libtiff, and OpenSlide from source to work around the problem. For more information, there is an ansible script that builds these libraries, and some notes on the process.
You may want to install optional utilities:
- memcached - this allows memcached to be used for caching
pip install --user numpy==1.10.2
The python libtiff library fails to include numpy as a dependency, which means that it must be installed manually before you can install large_image.
You may want to pip install optional modules:
- psutil - this helps determine how much memory is available for caching
- git clone https://github.com/girder/large_image.git
- cd large_image
- python setup.py install --user
