No dataset constants for "femnist" dataset

[meryemJanatiIdrissi]

when i run the experiments for femnist dataset i run to this error:

FileNotFoundError: [Errno 2] No such file or directory: 'dataset_constants/femnist_train_mean_std'

and other errors in the function update
update(self.updates, aggregation, max_update_norm=MAX_UPDATE_NORM)
specifically the "max_update_norm" parameter.

I tried to ignore these errors by not doing the normalization and deleting the "max_update_norm" parameter however the accuracy is very bad (0.05)

do you please have a solution for this?

Hello,

Sorry for the late response. We updated the dataset_constants folder with the EMNIST mean and std values. The update function works fine for me. Could you please post the full error message?

More details:

• The normalization allows for larger learning rates, leading to faster convergence. You can run it without the normalization, but you'll have to use a smaller learning rate, such as 0.05, for instance (with normalization, we use a learning rate of 1.0).

• The max_update_norm is just a safety check to ensure that a large unexpected update does not cause divergence. You do not need it to reproduce the experiments reported in our paper (i.e., you can safely set it to None).

Please let us know if you need anything else.

Best,
Krishna
