Non-determinism in model estimation

[roehst]

Hi, for the MLTR and RandomSurvivalForest I get different estimates for survival probabilities on each run.

Is there any parameter to regulate training?

I looked into it, made some code changes, and was able to get reproducible results within the same run (multiple calls to MLTR fit in the same script). But every time I run the script, I get another set of results. I believe it's related to PyTorch (pytorch/pytorch#7068), but even setting the seed in different places, I still can't get reproducible results in every run.
