`ValueError: /workplace/spconv/src/spconv/spconv_ops.cc 87 unknown device type` error about centerformer

[Machine-NO-Learning]

acturally conda is ok to do that, surely you use docker maybe based on some reasons like landing projects or your server cuda version which is also used by your friends that can't be changed.

this project is based on centerpoint, you can set env based on that, for spconv v1, I suggest that you:

1. git clone -b v1.2.1 https://github.com/traveller59/spconv.git --recursive
2. cd spconv && python setup.py bdist_wheel (maybe you will meet No CUDA compler find and no Cmake.txt in pyblind11, you can do export CUDA_HOME=/usr/local/cuda
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64:/usr/local/cuda/extras/CUPTI/lib64
   export PATH=$PATH:$CUDA_HOME/bin, and git clone --recurse-submodules https://github.com/pybind/pybind11.git in spconv/thirdparty/)
3. cd ./dist
4. pip install xxx.whl

then maybe you should setup multi_scale_deformable and iou_nms_cuda
you should go to det3d/ops/ and setup them

hope this can help you
