Say now I have a numpy array which is defined as,
[[1,2,3,4],
[2,3,NaN,5],
[NaN,5,2,3]]
Now I want to have a list that contains all the indices of the missing values, which is [(1,2),(2,0)]
at this case.
Is there any way I can do that?
np.isnan combined with np.argwhere
x = np.array([[1,2,3,4],
[2,3,np.nan,5],
[np.nan,5,2,3]])
np.argwhere(np.isnan(x))
output:
array([[1, 2],
[2, 0]])
