Hi there,

Was using pyNN 0.9 and python 2.7 for quite some time, recently converted to pyNN 1.0 and python 3.10, an error was spotted.

In ~/.local/lib/python3.10/site-packages/pyNN/parameters.py

299 if issubclass(expected_dtype, ArrayParameter) and isinstance(value, collections.Sized):

303 if isinstance(value[0], collections.Sized):

function collections has been changed to collections.abc by default in python 3.9+, so the correct usage should be

299 if issubclass(expected_dtype, ArrayParameter) and isinstance(value, collections.abc.Sized):

303 if isinstance(value[0], collections.abc.Sized):

The code has to be modifed or attribute error would occur when populations are made.

Regards,

Tiger

Hi,

Many thanks for the report. This has now been fixed, the fix was released in PyNN 0.10.1.
