from sklearn.metrics import confusion_matrix
import matplotlib.pyplot as plt
import numpy
import seaborn as sns

cm = numpy.array([[  6,  94],[ 80, 821 ]])

fig, ax = plt.subplots(figsize=(10,10)) # Adjust to fit

sns.set(font_scale=1.5) # Adjust to fit
sns.heatmap(cm, annot=True, ax=ax, cmap="Blues", fmt="g");  

# Labels, title and ticks
label_font = {'size':'15'}  # Adjust to fit
ax.set_xlabel('Predicted labels', fontdict=label_font);
ax.set_ylabel('True labels', fontdict=label_font);

title_font = {'size':'20'}  # Adjust to fit
ax.set_title('Confusion Matrix', fontdict=title_font);

ax.tick_params(axis='both', which='major', labelsize=20)  # Adjust to fit
labels = ['True', 'False']
ax.xaxis.set_ticklabels(labels);
ax.yaxis.set_ticklabels(labels);

plt.show()
