方便提供一个requirements安装环境，不然会有各种报错，
例如：
File "/home/sam_road-main/model.py", line 102, in forward
src_features = point_features[batch_indices, pairs[:, :, 0]]
IndexError: tensors used as indices must be long, byte or bool tensors

python3.8/site-packages/torch/nn/modules/transformer.py", line 437, in forward
return torch._transformer_encoder_layer_fwd(
RuntimeError: expected scalar type BFloat16 but found Float
