numpy find rows containing nan
# in each case returns array of bool
np.isnan(a).any(axis=1) # rows where any value is nan
np.isnan(a).all(axis=1) # rows where all values are nan
numpy find rows containing nan
# in each case returns array of bool
np.isnan(a).any(axis=1) # rows where any value is nan
np.isnan(a).all(axis=1) # rows where all values are nan
python numpy array check if all nans
np.all(np.isnan(numpy_array))
check nan values in a np array
array_has_nan = np.isnan(array_sum)
