save_potential

This keyword sets the number of of generations between writing a nep.txt checkpoint file. If <format> is set to 0 the output file name is formatted as nep_gen[generation].txt. If <format> is set to 1 the output file name is formatted as nep_y[year]_m[month]_d[day]_h[hour]_m[minute]_s[second]_generation[generation].txt. These model files can be used to monitor the training progress of your model. Additionally, if <save_restart> is set to 1 the nep.restart file is also written, following the naming format set by <format>. Note that the nep.restart file is the file that is required to continue training.

The syntax is:

save_potential <number_of_generations_between_save_potential> <format> <save_restart>

The default number of generations between saved model files is \(N=10^5\) and the output file names use the extended format.
