If you already have Python and Git, download NEMS:
git clone https://github.com/lbhb/NEMS
Add the NEMS library via pip (where ./NEMS
is the installation directory and -e
means editable mode,
which is not necessary, but is useful if you end up customizing your model fits):
pip install -e ./NEMS
NEMS libraries should now be loadable!
Conda is simple and popular platform for Python package management. NEMS does not currently have a conda package, but you can use conda to manage Python and your other packages. To install NEMS in a conda environment, first download and install Conda from here. Git should be installed with Conda.
Download NEMS:
git clone https://github.com/lbhb/NEMS
Create a NEMS environment, then activate it and install NEMS:
conda env create -n NEMS -f ./NEMS/environment.yml conda activate NEMS pip install -e ./NEMS
NWB: Support for reading datasets stored in Neurodata Without Borders (NWB) format. Pip install the allensdk packages as part of NEMS. You can run this either before or after the generic install described above:
pip install -e ./NEMS/[nwb]
Tensorflow: If you're using conda to manage packages, it's best to install Tensorflow via conda:
# without GPU (run on CPU): conda install tensorflow # or with GPU support: conda install tensorflow-gpu
If you're using pip, install Tensorflow support with pip:
pip install -e ./NEMS/[tensorflow]
Sphinx (if you want to be able to edit and regenerate documentation):
pip install -e ./NEMS/[docs]
We have found that Python 3 distributions compiled with the Intel MKL libraries are about twice as fast as the default Python implementations that come installed on many linux machines.
NEMS is designed to use Python 3. Backwards compatibility with Python 2 is untested and unsupported.
You may want to add NEMS to your python path. Eg, in Linux:
echo "export PYTHONPATH=\"\$PYTHONPATH:`pwd`/NEMS\"" >> ~/.bashrc source ~/.bashrc
