How to reduce/eliminate the "randomness" of the predicted skeleton?

[kts707]

Hi @zhan-xu

Thanks for the great work!

As discussed in #41, "randomness" mainly comes from random sampling. I tried to manually set a fixed seed before all the operations involving such random sampling. However, the randomness is still there...

I was wondering if there is any way to reduce/eliminate the result's randomness as my output differs by a lot in each run. Any suggestion/comment will be greatly appreciated!

So far as I tried, setting numpy.random.seed() and seed in sample_points_poisson_disk() could help reproduce results. e.g. codes here: https://github.com/zhan-xu/RigNet/blob/master/geometric_proc/common_ops.py#L50 samples = mesh.sample_points_poisson_disk(number_of_points=4000, seed=123)

Hi @CoolGua0113 ,

Thanks for your answer! I set the numpy seed and the seed in sample_points_poisson_disk(). However, I am still getting different results every time. Is there anything that you changed to get consistent results?

Nothing else sorry...I could get completely same results each run after setting these two seeds. Maybe you could check the input to RigNet(in create_single_data()) first? As mentioned by the author, the randomness of the network might be less important.

Did you set the numpy seed before every numpy operation that involves randomness?

I am basically running quick_start.py with numpy seed set before loading the network only, however, still getting different results in each run (the sample_points_poisson_disk() seed is also set to a deterministic number, and the input is also the same each time)
