Reproducibility of the results

[Yottaxx]

Hi, Thanks for your great job! I have followed the instruction of readme, but changed the DGL version with various versions. During the experimental stages, even with the same seed and same experimental environment, the results still have reproducibility problems. As seen in DGL instructions, after the version of 0.5, DGL by default chooses deterministic implementations for better reproducibility. I wonder what makes this repo has reproducibility problems? Thanks again.
