Is it possible to train specgan and wavegan pointing same train directory

[takeofuture]

In colab sample, https://colab.research.google.com/drive/1e9o2NB2GDDjadptGr3rwQwTcw-IrFOnm The model downloaded trained by "wavegan.py train" or "specgan.py train"?

After I execute training by

train_wavegan.py train ./train --data_dir ./wavedatadir

I see some audio generated then I executed

train_specgan.py moments ./train \ --datadir ./data/dir/wavedatadir \ --data_moments_fp ./train/moments.pkl and then

train_specgan.py train ./train \ --datadir ./data/dir/wavedatadir \ --data_moments_fp ./train/moments.pkl

I got error, I see the sample colab https://colab.research.google.com/drive/1e9o2NB2GDDjadptGr3rwQwTcw-IrFOnm It download sinle model set, I wonder if this is trained by specgan or wavegan or both If both how can I combine specgan and wavegan?

Thank you!
