Numpy expired deprecations

[JulienPeloton]

In Numpy https://numpy.org/devdocs/release/1.24.0-notes.html, the expired deprecations include np.float & np.bool. We started to clean our codes, but many of our dependencies still rely on it. For precaution, we should stick to numpy version 1.23.x and below, and identify which dependencies still rely on it (e.g. LIA).
