Comparisons against numpy.nan always result in False. Thus comparing an expression directly against numpy.nan is always unintended. The correct way to compare a value for NaN is to use the numpy.isnan function.
Our changes look something like this:
import numpy as np
a = np.nan
-if a == np.nan:
+if np.isnan(a):
pass

F.A.Q.​
Why is this codemod marked as Merge Without Review?​
We believe any use of == to compare with numpy.nan is unintended given that it is always False. Thus we consider this change safe.
