Dear Xavier,

I have recorded your problem as a feature request: https://github.com/nest/nest-simulator/issues/2623, please continue

Due to limited developer resources, I don't think we will be able to handle this with a very high priority, though. If you decide to give this a shot yourself, feel free to do so.

Cheers, Jochen!

Hello,

For the below code I get an error related to __cinit__ (Cython) when performing a deepcopy that includes a nest.spatial specification.

I am using NEST 3.3 and Python 3.8.12

Best,

Xavier
