Shouldn't we train pretrain_D?

[Smellly]

Plz tell us when do we set D_is_pretrain as True ?
And npz_paths = ["mscoco_51000.npz"] at

show-adapt-and-tell/show-adapt-tell/data_loader.py

Line 35 in 6daf82e

npz_paths = ["mscoco_51000.npz"]

is created by what code?

We found that the results are similar whether D (critic) is pre-trained or not.
The code is therefore not released here.
For Multi-modal Critic, it simply takes three classes of paired, unpaired and sentences generated from the pre-trained G to train the classifier.
In Domain Critic, sentences from source and target domains are used.

If you're interested, here is the npz file of negative samples from MSCOCO model at ckpt-51000.
