Problems installing topographica on ubuntu (version 12.04)

[ceball]

I received the following email from "jiangtao yang, School of Software &Microelectronics of Peking University"...

When I install to topographica on my ubuntu(version 12.04)，I have got a problem,and the detail information of problem is:

And the location of error is here:

Then I have looked the class of numbergen very carefully,but I have found that there is no attribute named constanttime. Though, my question is that how I can solve this problem.I really need your help.Thank you for your time.

I've asked for clarification about how Topographica was installed, so unless someone immediately knows what the problem is (e.g. from recent code changes), then we should wait for more information.

[philippjfr]

numbergen.constanttime hasn't existed for quite a while now and isn't mentioned anywhere in the current codebase, so I assume he is getting an outdated version of Topographica. Could you ask him where he downloaded Topographica from and sugggest he uses the latest version from Github.

[philippjfr]

It could be that he got the latest PyPI releases of Param and ImaGen, which means he'd get a version of numbergen without constanttime and one with constanttime. This might indicate that we should update the imagen release, since it may no longer be compatible with the latest param/numbergen release.

I have solved the problem. When I install the latest version of topographica once again,I have found that it can not install the param and paramtk package successfully,and the error messages is: (1)$ sudo pip install topographica Downloading/unpacking topographica Running setup.py egg_info for package topographica
