Needs Training datasets and Epoch running during Test stage on Semantic3D

> Hi @kxdkxd, 感谢你的建议！训练集数据只是load进去并没有使用，我们后续会修改一下code。此外，test需要跑两个epoch只是因为对于有些点云数据太大（比如说semantic3D中有的点云有几亿个点）无法直接一次性测试完，所以需要一块一块的进行测试。 > > 希望会有帮助！ Hello, I met the same question. It seems that you haven't fixed this problem.
