ValueError: left cannot be >= right on sns.heatmap

Question

I have this value of m:

array([[0.91992515, 0.978894  , 0.98183531, 0.99085009, 0.98576438,

when I execute:

sns_plot = sns.heatmap(m)

I get the following error:

ValueError: left cannot be >= right

What am I doing wrong?

Answer 1

Using np.array this worked perfectly for me

import numpy as np

m = np.array([[0.91992515, 0.978894  , 0.98183531, 0.99085009, 0.98576438,
