I am transferring learning from an existing model, and from my experience, there is a sweet spot of letting the model train to the data set, vs when it gets destructive to the pretrained model.

I wish to make as many network snapshots as possible,

from as far as I know, this value

network_snapshot_ticks = 1, 

governs the snapshot creation. I have increased said value and also decreased it to decimal values, yet have gotten any results.
