about: local variable 'step_size_min' referenced before assignment in pysurvival

[dadekandrew2010]

The error message is prompted by the step function in the rprop.py file in the user torch directory. You only need to initialize the variable that reports the error in this function, similar to step_size_min=[] def step(self, closure=None): ...... F.rprop(params, grads, prevs, step_sizes, step_size_min=step_size_min,
step_size_max=step_size_max, etaminus=etaminus, etaplus=etaplus)

I also have this issue.

I think this project died so I wouldn't expect an update. Shame as it seemed like a useful package
