from distiller.

resnet20_cifar_earlyexit has only 1 earlyexit.
you can use 1 earlyexit_threshold and 1 earlyexit_lossweight in your command:
e.g. --earlyexit_thresholds 0.9 --earlyexit_lossweights 0.2

from distiller.

Thanks!
The first epoch is finished, but another problem is shown below:

=> using early-exit threshold values of [0.9]

from distiller.

Hi - this is because the newer Pytorch 1.0 is deprecating the "reduce" parameter and using "reduction"

Either update to Pytorch 1.0 - or if you don't want to use the pre-release version, then change that line in the code to reduce='False'

from distiller.

I found this problem, too.
pytorch version must be >= 0.4.1

from distiller.

To be consistent with the rest of Distiller (which assumes version 0.4.0 of Pytorch), I will be taking the parameter back to the 0.4.0 method of calling. The parameter should be reduce=False

If you want to run right now - make the change yourself. I'll be submitting a patch in the upcoming day or two.

@haim-barad It works. Thanks!
