Background
This PR resolves #28, where the use of
np.NAN
inheatmap.py
causes anAttributeError
in NumPy version 2.1. To resolve this, all instances ofnp.NAN
are replaced withnp.nan
, ensuring compatibility with both current and future versions of NumPy, as recommended by the NumPy stable documentation and the NumPy 1.26 documentation.Current Behavior
Using
np.NAN
results inAttributeError: module 'numpy' has no attribute 'NAN'
, causing errors in NumPy 2.1.Expected Behavior
The code will now use
np.nan
for NaN handling, eliminating theAttributeError
and ensuring compatibility across NumPy versions.
