Code checking with different version of MinkowskiEngine

[tonghe90]

I check out the newest version of MinkowskiEngine, but the training process is quite different from the previous version(c52ba2f). Could you please check the code for scannet segmentation

The loss curve is quite different (previous is better), and the newest version fails to load 4 examples in a batch, while the previous is ok

Hi Tong,

Could you pull from the SpatioTemporalSegmentation repository master as well?

The possible cause of the issue is that we prepend the batch indices before the coordinates from ME v0.4 (https://stanfordvl.github.io/MinkowskiEngine/sparse_tensor.html#MinkowskiEngine.SparseTensor.SparseTensor) and I updated the SpatioTemporalSegmentation repository as well.

In general, it is discouraged to directly generate batched coordinates or get decomposed coordinates. Please refer to the warning section of the Sparse Tensor API to make your code up-to-date with the latest Minkowski Engine.
