How to find the labels of the confusion matrix in Python?

""" In order to find the labels just use the Counter function to count 
the records from y_test and then check row-wise sum of the confusion 
matrix. Then apply the labels to the corresponding rows using the 
inbuilt seaborn plot as shown below"""

from collections import Counter

import seaborn as sns
import matplotlib.pyplot as plt     

ax= plt.subplot()
sns.heatmap(cm, annot=True, fmt='g', ax=ax);  #annot=True to annotate cells, ftm='g' to disable scientific notation

# labels, title and ticks
ax.set_xlabel('Predicted labels');ax.set_ylabel('True labels'); 
ax.set_title('Confusion Matrix'); 
ax.xaxis.set_ticklabels(['business', 'health']); ax.yaxis.set_ticklabels(['health', 'business']);
