Failure in pairwise distance numpy implementation

[adarshyoga]

The pairwise distance numba implementation with numpy calls fails since numba-dpex does not currently support dpnp.sum calls with non-default axis. See failing code snippet below.

@dpjit
def pairwise_distance(X1, X2, D):
    x1 = np.sum(np.square(X1), axis=1)
    x2 = np.sum(np.square(X2), axis=1)
    np.dot(X1, X2.T, D)
    D *= -2
    x3 = x1.reshape(x1.size, 1)
    np.add(D, x3, D)
    np.add(D, x2, D)
    np.sqrt(D, D)

How to reproduce:

Follow instructions to setup dpbench. Run pairwise distance - python -c "import dpbench; dpbench.run_benchmark("pairwise_distance")"

I see that there are more issues than just sum. Let us reopen
