Attribute error: sequential model has no loss function about snn_toolbox HOT 3 CLOSED

The datagenerator should work fine in SNN toolbox, I've used it regularly for ImageNet and other datasets.

Do you get the same error also under different conditions (e.g. using one of the example scripts)? I would need to see more details to be able to help with this (error stack trace, network architecture / training script).

Hi Bodo,

Roshan and I are in the same team.
We are able to run the Keras trained .h5 model in snntoolbox using INI.
However we encountered an error during weight normalisation. Wonder what
happpend. Below is the message: Rgds Del

Hmm, the toolbox tries to load scale factors from a previous run from disk, to save computation time. If the user changed the network architecture in the same working directory, it can lead to a mismatch with the saved dict. Try deleting the normalization folder in your working dir.
