Problem running FINN examples

[Galapple]

I have XRT version 2.11.634 and I am reciving this error while trying to run 1_cifar10_with_cnv_networks, can anyone specify what needs to be done in order to run this notebook?

Below are the cells that I run so far:

from finn_examples import models
print(list(filter(lambda x: "cifar10" in x, dir(models))))

accel = models.cnv_w1a1_cifar10()

I have also tryed with a super user and it didn't helped.

Thank you

Hi @Galapple,
Could you please post this issue on finn-examples?
You can link the created issue in this thread but I am not sure that the finn-examples maintainer screen the finn GitHub Discussions regularly.

Ok I will, thanks.
