@jturner314 any chance we can merge this PR? New release will be appreciated

This PR works for me. It was necessary to use ort + ndarray + ndarray-npy together because ort depends on ndarray 0.16. In case other people are running into similar problems, you can use this pull request's version of ndarray-npy with:

ndarray-npy = { git = "https://github.com/Dirreke/ndarray-npy", branch = "bump-ndarray" }

in your Cargo.toml

I've now released version 0.9.0, which bumps the ndarray and zip dependencies, among other changes. See RELEASES.md.
