Hi @GEB72. Unfortunately I won’t be able to help with the specific error – from the error message I’d say it has to do with an incompatibility of the code for a 64bit Windows, but I can’t dig into this any further. Did you try using the Brian1 docker image: [Container image for Brian 1 — Brian 2 2.5.1.post0.dev88 documentation](https://brian2.readthedocs.io/en/latest/introduction/brian1_to_2/container.html)? I _think_ it should fix the issue (since in the docker container runs on Linux), but I am not 100% sure either.

All that said, several users have tried adapting that code to Brian 2, see e.g. [GitHub - sdpenguin/Brian2STDPMNIST: Brian 2 version of Paper "Unsupervised Learning of digit recognition using STDP"](https://github.com/sdpenguin/Brian2STDPMNIST) – it might be worth using that straight away. Also have a look at the discussion here: [Unsupervised learning of digit recognition using spike-timing-dependent](https://brian.discourse.group/t/unsupervised-learning-of-digit-recognition-using-spike-timing-dependent/189)
