Femnist: IndexError: list index out of range.

[colin-byrneireland]

When I run python main.py -dataset femnist -model cnn -lr 0.06 --minibatch 0.1 --clients-per-round 3 --num-rounds 20

I get the following

======================End of Report==========================
Clients in Total: 0
--- Random Initialization ---
--- Round 1 of 20: Training 3 Clients ---
Traceback (most recent call last):
File "main.py", line 186, in

base = [0] * len(self.updates[0][1])
IndexError: list index out of range

Any ideas welcome.

Sorry forgot to mention that I just used the default code no modifications at all. Not sure if I'm doing a prep step wrong, compatibility issue or issue with the default code ?

I have the same problem.

Did anyone find a solution to this? :(

Same for CNN in celebA, maybe it is the common bug for image-based classification?

I also got an error when running python main.py -dataset femnist -model cnn -lr 0.06 --minibatch 0.1 --clients-per-round 3 --num-rounds 2000.

My running environment is docker. I successfully generated data by leaf/data/femnist/ $> ./preprocess.sh -s niid --sf 0.05 -k 0 -t sample --smplseed 1549786595 --spltseed 1549786796, but got an error when running the model:

I think, you didn't load the dataset properly.
