Stage 0 scripts and config

[Sreyan88]

Hi there,

Great work! Could you please provide us with the pretrain_stage0.sh or the config file (except the log file). We would like to reproduce some experiments! Thank You!

I used something similar to this (if you find anything here inconsistent with the log, please feel free to replace it). The stage-0 was trained on an other server at Northwestern with 3x RTX-A6000, which I only kept the log and pre-trained weights.
