Fix Pytest error in test cases due to Numpy 2.0 incompatibility

[darrylong]

Description

In our unit tests, pytest throws failures due to incompatibility of the np.Inf being deprecated (A deprecation in Numpy 2.0).

We pin the version of numpy<2.0.0, and scipy<=1.13.1. In a separate issue and PR, we will resolve codes regarding Numpy 2.0 errors.

Let's also set an upper bound for Numpy and Scipy version in setup.py.
