Dear Inton,

I can reproduce this error, and have created an issue for it on the NEST-simulator Github page: https://github.com/nest/nest-simulator/issues/2138 Further discussion will take place there.

Thanks for reporting this! Best wishes, Stine

I think there is an error in https://nest-simulator.readthedocs.io/en/stable/auto_examples/plot_weight_ma...

· min(E_neurons)and min(I_neurons) should be replace to

· min(E_neurons.tolist()) and min(I_neurons.tolist())or some other way to get the right values

Suggestion:

The file plot_weight_matrices.py just contain a def plot_weight_matrices(E_neurons, I_neurons). If it had a complete code to create nodes, assign weights then plot the weight matrixes, the error could have been caught automatically (CI/CD)?

Best,

Inton
