BUG: Intel Mac tribulations

[elc45]

Describe the issue:

Can't compile a pymc model.

Reproducable code example:

import nutpie
import pandas

data = pd.read_csv(pm.get_data("radon.csv"))
data["log_radon"] = data["log_radon"].astype(np.float64)
county_idx, counties = pd.factorize(data.county)
coords = {"county": counties, "obs_id": np.arange(len(county_idx))}

# Create a simple hierarchical model for the radon dataset
with pm.Model(coords=coords, check_bounds=False) as pymc_model:
    intercept = pm.Normal("intercept", sigma=10)

    # County effects
    raw = pm.ZeroSumNormal("county_raw", dims="county")
    sd = pm.HalfNormal("county_sd")
    county_effect = pm.Deterministic("county_effect", raw * sd, dims="county")

    # Global floor effect
    floor_effect = pm.Normal("floor_effect", sigma=2)

    # County:floor interaction
    raw = pm.ZeroSumNormal("county_floor_raw", dims="county")
    sd = pm.HalfNormal("county_floor_sd")
    county_floor_effect = pm.Deterministic(
        "county_floor_effect", raw * sd, dims="county"
    )

    mu = (
        intercept
        + county_effect[county_idx]
        + floor_effect * data.floor.values
        + county_floor_effect[county_idx] * data.floor.values
    )

    sigma = pm.HalfNormal("sigma", sigma=1.5)
    pm.Normal(
        "log_radon", mu=mu, sigma=sigma, observed=data.log_radon.values, dims="obs_id"
    )

compiled_model = nutpie.compile_pymc_model(pymc_model)

Not urgent. Just documenting so it's there.
