For example ,when feat_keys=("coord") , that means feat_keys only have one element, the transform.py file will trigger a error

Hi, kindly remind:

("coord") == "coord"
("coord",) == Sequence(["coord"])
["coord"] == Sequence(["coord"])

Hi, kindly remind:

("coord") == "coord"
("coord",) == Sequence(["coord"])
["coord"] == Sequence(["coord"])

When I rewrite this code: feat_keys=(["coord"]), it will trigger another bug:
File "/root/anaconda3/envs/ptv3/lib/python3.9/site-packages/spconv/pytorch/conv.py", line 169, in _conv_forward
assert input.features.shape[
AssertionError: channel size mismatch
