pytorch3d报错：RuntimeError: Not compiled with GPU support.

解决方法：编译之前：加上指令：

解决方法：pytorch3d 安装命令（ubuntu），成功！！！

测试代码：

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：

解决方法：pytorch3d 安装命令（ubuntu），成功！！！

pip install --no-index --no-cache-dir pytorch3d -f https://dl.fbaipublicfiles.com/pytorch3d/packaging/wheels/py38_cu113_pyt1110/download.html
