new failure in regular test

Hello, I just noticed some new failures in tests I run. Perhaps this trace is useful. For me things are working on 3.7 tests but not 3.8. Peter

    # Warm up with random points
    x_tries = random_state.uniform(bounds[:, 0], bounds[:, 1],
                                   size=(n_warmup, bounds.shape[0]))
    ys = ac(x_tries, gp=gp, y_max=y_max)
    x_max = x_tries[ys.argmax()]
    max_acq = ys.max()

    # Explore the parameter space more throughly
    x_seeds = random_state.uniform(bounds[:, 0], bounds[:, 1],
                                   size=(n_iter, bounds.shape[0]))
    for x_try in x_seeds:
        # Find the minimum of minus the acquisition function
        res = minimize(lambda x: -ac(x.reshape(1, -1), gp=gp, y_max=y_max),
                       x_try.reshape(1, -1),
                       bounds=bounds,
                       method="L-BFGS-B")

        # See if success
        if not res.success:
            continue

        # Store it if better than previous minimum(maximum).

      if max_acq is None or -res.fun[0] >= max_acq:
