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. Alberto

During handling of the above exception, another exception occurred:

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

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,
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.
