Encoder weights not frozen after phase 1 with discrete configuration

[snnithya]

Today I realised that the encoder weights aren't being frozen after phase 1 of training in the DiscreteEncoder module (used by discrete.gin config) and gradients are still being backpropogated through the encoder in phase 2 of training as well. I was wondering if this was intentional and if so why? I'm a bit confused by this since according to the original RAVE article, the encoder is supposed to be 'frozen' during phase 2 of training. Thanks in advance!
