CUDA kernel for MSDeformAttn

After preparing the required environment, run the following command to compile CUDA kernel for MSDeformAttn:

CUDA_HOME must be defined and points to the directory of the installed CUDA toolkit.

cd clouds/modeling/pixel_decoder/ops
sh make.sh

Building on another system

To build on a system that does not have a GPU device but provide the drivers:

TORCH_CUDA_ARCH_LIST='8.0' FORCE_CUDA=1 python setup.py build install

Example conda environment setup

conda env create --file environment_clouds.yml
pip install -U openmim
mim install mmcv
