When loading the APRILE model, it does not matter if the output shows the following information:

Load BP Gene Ontology Analysis ...
fisher module not installed.  Falling back on scipy.stats.fisher_exact
 81% 16,936 of 20,913 population items found in association

Load CC Gene Ontology Analysis ...
fisher module not installed.  Falling back on scipy.stats.fisher_exact
 85% 17,872 of 20,913 population items found in association

Load MF Gene Ontology Analysis ...

 83% 17,408 of 20,913 population items found in association

There are two options for choosing a fisher function: using the fisher or scipy packages. If the fisher function from the first source fails to run on your machine, then the scipy fisher function is used.

If you do want to use the fisher source, please see the instructions [here] to install it.
