Hi,
suddenly, I am starting having this error.
I have both PyNN and Nest installed.
If it's more related to the PyNN community, I will forward this message to
them, but at this moment I don't know if it's more related to Nest or PyNN
side.
Maybe some of you have met a similar issue.

Hi Alberto,
Which versions of PyNN and of NEST are you using?
The current version of PyNN (0.9.6) does not work with NEST 3.0. PyNN 0.10.0 will be
released soon (in September), and that will support NEST 3.
If you’re happy to install a development version of PyNN from Github, you can use this
branch: https://github.com/apdavison/PyNN/tree/nest-3

Hi Andrew,
yes, I have PyNN == 0.9.6, so I will try to downgrade to see if that's the
issue.
In the other case, I can install the development version of PyNN
Thanks for the information,
Alberto

Dear Andrew,
I have installed PyNN==0.10.0.dev, but actually I am receiving the same
error with nest3
IN the bottom the errors. There two related to nest3, one about the
'install' module and the other about the attribute 'kernel'
Thanks for the hints.

Is this NEST version 3.0? If yes, PyNN does not yet support it
completely. Please see:
