How to fix builtins.TypeError: '>' not supported between instances of 'numpy.ndarray' and 'float'?

Question

Python

I want to write a neural network that recognizes what language the words are written in. I'm trying to implement using
sklearn.naive_bayes import GaussianNB but an error occurs. How can this be fixed?

#coding=utf8
import numpy as np
from sklearn.naive_bayes import GaussianNB

x_training = np.array()
y_training = np.array(['ru', 'en', 'en', 'ru'])

clf = GaussianNB()
clf.fit(x_training, y_training)

print(clf.predict(np.array(['при'])))

Answer 1

So
from sklearn.naive_bayes import GaussianNB
or
clf = BernoulliNB()

Answer 2

First you need to vectorize the input https://scikit-learn.org/stable/modules/feature_ex...
