I failed to compress the downsampled point cloud file with draco_encoder. about draco HOT 1 OPEN

I ran the compressed code directly from the command line, and here is the result:

So,the reason is that use open3d's o3d.io.write_point_cloud("longdress_vox10_1051_0.8_float32.ply", down_sampled_pcd, write_ascii=False) to save a point cloud file. Its xyz coordinate type is saved as' double 'by default, so I was wondering if I could just compress it with the object, But the command you gave to compress draco_cencoder also needs to pass in the path of the necessary point cloud files such as./draco_encoder -i./1/longdress_vox10_1051.ply -o out.drc, so now both sides are stuck, So can you compress the point cloud object pcd directly instead of the point cloud file path, because once you save the file with open3d, its type xyz will become a double, and draco_encoder requires that the type of the point cloud file point be float and int.
So can you tell me the way to this problem?
