Performance of SpMiddlePillarEncoder34 and SpMiddlePillarEncoder34A

[shawnding]

Hi,

Thank you for your excellent work! I noticed there are two different implementations of pillarnet-34 in the code, SpMiddlePillarEncoder34 and SpMiddlePillarEncoder34A. But the SpMiddlePillarEncoder34A seems not mentioned in the paper.

Was the PillarNet-34 result of the paper based on the SpMiddlePillarEncoder34 or SpMiddlePillarEncoder34A? What's the difference between them in terms of performance?

Also, could you give the link of the supplementary material of PillarNet? I have tried arXiv and ECCV official page but failed to find it. Thanks a lot!
