How can I change initial of max_step?

[kobrafarshidi]

I am trying to retrain my model that trained before with command(model.load_from_chechponit(path))
but the issue is when I want to see tensorboard_logger it starts training from beginning for max_step and acc.
I was hoping the increase mode should be continuous and not start from the beginning max_step and acc.
For example, in last step max_step=50K, acc=0.30 and I was hoping that these two would increase in the next retrain but in the first training max_step start with 1700 and acc=0.22
In below I attach that source.
How can I change start of max_step and acc (change the initial value of max_step)?
