Could you confirm which install instructions you followed?

jbednar commented 8 years ago

Those look like outdated versions of the libraries; there's no constanttime in imagen/__init__.py anymore. Probably you're mixing incompatible versions. The latest versions of all the libraries (topographica (via github), param (via pip or conda), and imagen (via pip; conda version coming soon)) should work, or else the versions from the last official release 0.9.8.

Hima-Mehta commented 8 years ago

I have installed all packages via pip and my python version is 2.7.11

jbednar commented 8 years ago

Maybe try "pip install --upgrade topographica"? If that doesn't work, please report the versions of topographica, param, and imagen that you have installed, e.g. by importing them and printing the .__version__ attribute.

Could you tell me the versions of libraries used in som_retinotopy.ipynb ? I have my SOM working with topographica 0.9.8 but how can I use .grid() to see my plots without GUI.! If holoviews support that please tell me compatible version.

We don't use different versions for different notebooks, in general; usually the notebooks all come together with a particular Topographica version, and all of them should work with the same underlying libraries. Certainly the som_retinotopy.ipynb that's distributed with Topographica 0.9.8 should work with the libraries used by 0.9.8. It may be that the very latest som_retinotopy.ipynb on github needs to be updated to work with the latest versions of holoviews and featuremapper, but if you stay on 0.9.8 consistently everything should work.
