ImportError: cannot import name IafCell

I am using the latest version of libNeuroML built from its current development branch. What version should I be using @pgleeson ?

[pgleeson]

Can you test that the examples run in your development branch of libNeuroML? Try:

cd libNeuroML/neuroml/examples/
python build_network.py

There should be an import for IafCell in build_network.py

[pgleeson]

Sorry, meant https://github.com/NeuralEnsemble/libNeuroML/blob/development/neuroml/examples/build_network.py, but IafCell (not the older IaFCell) is here too.

Think you have an old version of libNeuroML lurking around...

[slarson]

OK I got past that one. There were old versions lurking. Thanks!

[aribrich]

Is there another reason IafCell might not be found? I am also trying to run c302_A.py, and have the same import error. I checked the pip upgrade to make sure I have the latest version, and I do. Any ideas?

[pgleeson]

It's best to install libNeuroML directly from source using:

git clone https://github.com/NeuralEnsemble/libNeuroML.git
cd libNeuroML
git checkout development
sudo python setup.py install 

This version has reduced the dependencies on numpy to only require that if you use some of the advanced functionality.

I'll be updating the docs and the pip version in the next few days when we make the NeuroML v2beta3 release...
