returned pyarray not able to convert to vec

[DennisZhangOiler]

my code:

let inverted = test
            .call1(PyTuple::new_bound(py, &[a]))
            .unwrap()
            .downcast_into::<PyArray3<u8>>()
            .unwrap();
        println!(
            "inverted shape: {:?}, len: {}",
            inverted.shape(),
            inverted.len()
        );
        let v = inverted.to_vec().unwrap();
        println!("inverted vector size: {:?}", v.len());

output:

inverted shape: [360, 640, 3], len: 691200
