How to get epoch based trained weights for detectnet_v2?

Training a model with custom dataset by using detectnet_v2 in TLT-V2. Trained for 500 epochs and got goot mAP at 100th epoch. How to find the 100 epoch’s .tlt file in result folder? Only steps are mentioned on the .tlt file names, not with the epochs

eg :

model.step-0.ckzip
model.step-0.tlt
model.step-10000.ckzip
model.step-10000.tlt
model.step-10400.ckzip
model.step-10400.tlt
model.step-10800.ckzip
model.step-10800.tlt
model.step-11200.ckzip
model.step-11200.tlt
model.step-11600.ckzip
model.step-11600.tlt
model.step-1200.ckzip
model.step-1200.tlt
