# Designing Network Design Spaces ## Introduction <!-- [BACKBONE] --> We implement RegNetX models in 3D detection systems and provide their first results with PointPillars on nuScenes and Lyft dataset. The pre-trained modles are converted from [model zoo of pycls](https://github.com/facebookresearch/pycls/blob/master/MODEL_ZOO.md) and maintained in [mmcv](https://github.com/open-mmlab/mmcv). ``` @article{radosavovic2020designing, title={Designing Network Design Spaces}, author={Ilija Radosavovic and Raj Prateek Kosaraju and Ross Girshick and Kaiming He and Piotr Dollár}, year={2020}, eprint={2003.13678}, archivePrefix={arXiv}, primaryClass={cs.CV} } ``` ## Usage To use a regnet model, there are two steps to do: 1. Convert the model to ResNet-style supported by MMDetection 2. Modify backbone and neck in config accordingly ### Convert model We already prepare models of FLOPs from 800M to 12G in our model zoo. For more general usage, we also provide script `regnet2mmdet.py` in the tools directory to convert the key of models pretrained by [pycls](https://github.com/facebookresearch/pycls/) to ResNet-style checkpoints used in MMDetection. ```bash python -u tools/model_converters/regnet2mmdet.py ${PRETRAIN_PATH} ${STORE_PATH} ``` This script convert model from `PRETRAIN_PATH` and store the converted model in `STORE_PATH`. ### Modify config The users can modify the config's `depth` of backbone and corresponding keys in `arch` according to the configs in the [pycls model zoo](https://github.com/facebookresearch/pycls/blob/master/MODEL_ZOO.md). The parameter `in_channels` in FPN can be found in the Figure 15 & 16 of the paper (`wi` in the legend). This directory already provides some configs with their performance, using RegNetX from 800MF to 12GF level. For other pre-trained models or self-implemented regnet models, the users are responsible to check these parameters by themselves. **Note**: Although Fig. 15 & 16 also provide `w0`, `wa`, `wm`, `group_w`, and `bot_mul` for `arch`, they are quantized thus inaccurate, using them sometimes produces different backbone that does not match the key in the pre-trained model. ## Results ### nuScenes | Backbone | Lr schd | Mem (GB) | Inf time (fps) | mAP |NDS| Download | | :---------: | :-----: | :------: | :------------: | :----: |:----: | :------: | |[SECFPN](../pointpillars/hv_pointpillars_secfpn_sbn-all_4x8_2x_nus-3d.py)|2x|16.4||35.17|49.7|[model](https://download.openmmlab.com/mmdetection3d/v0.1.0_models/pointpillars/hv_pointpillars_secfpn_sbn-all_4x8_2x_nus-3d/hv_pointpillars_secfpn_sbn-all_4x8_2x_nus-3d_20200620_230725-0817d270.pth) &#124;
