The load_model function fails at the time of loading a NaiveBayes model

[afard]

Here is the reproducer:

from verticapy.machine_learning.vertica.model_management import load_model
from verticapy.datasets import load_iris
from verticapy.learn.naive_bayes import NaiveBayes

iris_vd = load_iris()
model = NaiveBayes("test_model")
model.fit(iris_vd, ["SepalLengthCm", "SepalWidthCm", "PetalLengthCm", "PetalWidthCm"], "Species")

new_model = load_model("test_model")
