If you do not have administrator (root-level) acccess to the system you would like to run NeuronetExperimenter
on, this guide describes how to install NeuronetExperimenter in a
different location than the default location that was described in the previous installation guide. This guide assumes that you have already read through the default installation guide. Once you have made these changes and
built your NeuronetExperimenter binary executable, you should see no difference
between the behavior of the default install and this install with
regards to how the operations of the program and associated scripts are performed.
are two critical differences between this installation and the normal
installation. The first important
change is to set the appropriate environment variables, so that you get
the behavior expected when running through the tutorials. The second is that you should configure each of NeuronetExperimenter's
dependencies to be installed in a different location, as well as NeuronetExperimenter's buildModelCode.py script to recognize this change. This is only
necessary if Open-MPI and GSL are NOT already installed by the
system administrator, which is probably the case if you are working through this guide.
Setting the Appropriate Environment Variables
should set the PYTHONPATH, PATH, and NNE_BIN_PATH variables to include
the directory you want to install BEFORE running './configure',
'make' and 'make install'. The environment variable topic shows how to
conveniently set all three of these variables in the bash shell environment
starting at the description of NNE_BIN_PATH.
Configuring the Installation of NeuronetExperimenter's Compilation Dependencies
pick a directory that you can install the other library dependencies.
For example, a sub-directory of your home-directory such as /Users/john/NNE_deps. Now,
every time you run a configure script for the dependencies (as
described in the basic installation guide), append this directory similar to the following command:
> ./configure --prefix=/Users/john/NNE_deps/
Then, after typing 'make', simply type 'make install' for each dependency (without the sudo command described in the basic installation guide).
Each of these dependencies will place files into a include/ and lib/ sub-directory of the directory you specified as the configured prefix. NeuronetExperimenter's configure script needs to be able to find these, so like the standard Unix configure command, you need to pass this information to the configure script in the following manner:
The addition of these arguments is only necessary the first time you
run the script as the options are cached for later execution of the configure script. To revert back to the default installation paths, remove the .configure.conf file, which is located in the same directory as the configurescript.
