Training script for 7B version

Would it be possible to release a training script for the 7B model? Preferably for the stage-1 training, but the other stages are also interesting. If this is not possible, what parameters need to be altered/added in the .sh files

Start by reviewing the existing .sh files and how they configure training for the available model sizes. Compare the stage-1 setup with the requested 7B model and determine which parameters would need to be altered or added. Done means either a usable 7B training script, preferably for stage 1, or documented parameter changes for the shell scripts.
