Does FocalsConv supports spconv1.2.1? #25

The released ckpt file was trained on OpenPCDet 0.3.0, but it applied spconv2.0, right? When I use latest pcdet(0.6.0), I encounter this error (using spconv 1.2.1) as following: AttributeError: 'SparseConvTensor' object has no attribute 'replace_feature' I don't know whether this pcdet 0.5.2 supports spconv 1.2.1. Anyway, how to run FocalsConv on spconv 1.2.1 is what I am concerned.

Our implementation is previously based on spconv 1x. That is why the checkpoints are based on spconv 1x.

You can follow this doc to check the difference between the usage of spconv 1x and spconv 2x. And modify the code to spconv 1x. This is not a hard job.

get it now. Thanks!
