FORCE_CUDA=1 works for me. Thanks!

      args = (points,cloud_to_packed_first_idx,num_points_per_cloud,image_size,radius,points_per_pixel,bin_size,max_points_per_bin,)# pyre-fixme[16]: Module `pytorch3d` has no attribute `_C`.idx, zbuf, dists = _C.rasterize_points(*args)ctx.save_for_backward(points, idx)ctx.mark_non_differentiable(idx)return idx, zbuf, dists

解决方法：编译之前：加上指令：

set FORCE_CUDA=1

报错：没有指定CUDA_HOME

方法1 重新安装命令 没测：

pip install "git+https://github.com/facebookresearch/pytorch3d.git"

方法2：
