how to convert .pt into onnx for pointpillars of mmdetection3d?

[sylivahf]

@NVIDIA-AI-IOT thank you for your works，this is very helpful for me. but there are some questions in mmdet3d conversion：i can't directly convert the model of mmdet3d, and i have no specific idea of revision ，because there are differences in the definition and use of pointpillars in mmdet3d and pcdet。 --------------mmdet3d-pointpillars-------------------- 0 backbone.blocks.0.0.weight 1 backbone.blocks.0.1.weight 2 backbone.blocks.0.1.bias 3 backbone.blocks.0.3.weight 4 backbone.blocks.0.4.weight 5 backbone.blocks.0.4.bias 6 backbone.blocks.0.6.weight 7 backbone.blocks.0.7.weight 8 backbone.blocks.0.7.bias 9 backbone.blocks.0.9.weight 10 backbone.blocks.0.10.weight 11 backbone.blocks.0.10.bias 12 backbone.blocks.1.0.weight 13 backbone.blocks.1.1.weight 14 backbone.blocks.1.1.bias 15 backbone.blocks.1.3.weight 16 backbone.blocks.1.4.weight 17 backbone.blocks.1.4.bias 18 backbone.blocks.1.6.weight 19 backbone.blocks.1.7.weight 20 backbone.blocks.1.7.bias 21 backbone.blocks.1.9.weight 22 backbone.blocks.1.10.weight 23 backbone.blocks.1.10.bias 24 backbone.blocks.1.12.weight 25 backbone.blocks.1.13.weight 26 backbone.blocks.1.13.bias 27 backbone.blocks.1.15.weight 28 backbone.blocks.1.16.weight 29 backbone.blocks.1.16.bias 30 backbone.blocks.2.0.weight 31 backbone.blocks.2.1.weight 32 backbone.blocks.2.1.bias 33 backbone.blocks.2.3.weight 34 backbone.blocks.2.4.weight 35 backbone.blocks.2.4.bias 36 backbone.blocks.2.6.weight 37 backbone.blocks.2.7.weight 38 backbone.blocks.2.7.bias 39 backbone.blocks.2.9.weight 40 backbone.blocks.2.10.weight 41 backbone.blocks.2.10.bias 42 backbone.blocks.2.12.weight 43 backbone.blocks.2.13.weight 44 backbone.blocks.2.13.bias 45 backbone.blocks.2.15.weight 46 backbone.blocks.2.16.weight 47 backbone.blocks.2.16.bias 48 neck.deblocks.0.0.weight 49 neck.deblocks.0.1.weight 50 neck.deblocks.0.1.bias 51 neck.deblocks.1.0.weight 52 neck.deblocks.1.1.weight 53 neck.deblocks.1.1.bias 54 neck.deblocks.2.0.weight 55 neck.deblocks.2.1.weight 56 neck.deblocks.2.1.bias 57 bbox_head.conv_cls.weight 58 bbox_head.conv_cls.bias 59 bbox_head.conv_reg.weight 60 bbox_head.conv_reg.bias 61 bbox_head.conv_dir_cls.weight 62 bbox_head.conv_dir_cls.bias 63 voxel_encoder.pfn_layers.0.norm.weight 64 voxel_encoder.pfn_layers.0.norm.bias 65 voxel_encoder.pfn_layers.0.linear.weight
