n_threads is not supported in Open3D 0.9.0

http://www.open3d.org/docs/0.9.0/python_api/open3d.geometry.TriangleMesh.html?highlight=create_from_point_cloud_poisson as title

so we have to delete n_threads in this function

def run_poisson(pcd, depth, n_threads, min_density=None):
    mesh, densities = o3d.geometry.TriangleMesh.create_from_point_cloud_poisson(
        pcd, depth=depth
    )

Yes, our Open3D's version is 0.15.2, so we can activate n_threads. If you Open3D doesn't support multiple threads, you can delete n_threads.
