i am trying to run the Mnist repository but got the following error.need your help to resolve this issue.

Hi. I think that Brian scripts might not be fully compatible with jupyter notebooks (they did not exist yet when Brian was written), please run scripts in the standard way (python ...). If you still have trouble running things from the stdp-mnist repository, try getting support from their end.

Please note that we no longer develop Brian 1.x and only provide very basic maintenance support -- the current version is Brian 2 (https://github.com/brian-team/brian2).
