23 sty 2024 · In NumPy, to replace NaN (np.nan) in an array (ndarray) with any values like 0, use np.nan_to_num(). Additionally, while np.isnan() is primarily used to identify NaN, its results can be used to replace NaN. You can also replace NaN with the mean of the non-NaN values.
You can also use np.where to replace a number with NaN. arr = np.where(arr==NDV, np.nan, arr) For example, the following result can be obtained via. arr = np.array([[1, 1, 2], [2, 0, 1]]) arr = np.where(arr==1, np.nan, arr) This creates a new copy (unlike A[A==NDV]=np.nan) but in some cases that could be useful.

23 sty 2024 · In NumPy, to remove rows or columns containing NaN (np.nan) from an array (ndarray), use np.isnan() to identify NaN and methods like any() or all() to extract rows or columns that do not contain NaN. Additionally, you can remove all NaN values from an array, but this will flatten the array.
7 wrz 2022 · Numpy package provides us with the numpy.nan_to_num() method to replace NaN with zero and fill positive infinity for complex input values in Python. This method substitutes a nan value with a number and replaces positive infinity
