ndarray version limitation (0.15.6)?

[humphreylee]

Just curious if ndarray version is designed/tested/limited to only max 0.15.6 at the moment? I tried version 0.16.0 or 0.16.1, compiling the same code spits tons of error. As MWE, I use this repository's lbfgs example, with updated Cargo.toml ndarray to 0.16.1, the following error appeared.
