Hi

Sorry for the trouble - I think we have broken topographica's packaging.

You can either follow the instructions below to get the latest "official" topographica release (0.9.8), which is now quite old, or you can wait for a developer to help you with your other request (#594) about using the latest git version of topographica.

To get topographica 0.9.8 to work, please follow "method 2" from https://github.com/ioam/topographica/issues/581#issuecomment-52298088:

pip uninstall topographica imagen paramtk param
pip install -r toporeq.txt

where toporeq.txt is:

topographica
param==1.0
paramtk==0.8
imagen==1.0
jlstevens commented 10 years ago

This error is due to an old version of param being used with a more recent (git) version of Topographica and I think the problem should be resolved by following the installation instructions above

Unless there are any new problems relating to this, can we now close this issue?

Sure; it can be reopened if the problem persists.
