Python How to get the index of a maximum element in a NumPy array
It calculates the index of the maximum element of the array across all axis not along a given axis as the OP asks it is wrong Moreover if there is more than one maximum it retrieves the indices of only the first maximum this should be pointed out
How to Get the Index of Max Value in NumPy Array Statology, You can use the following methods to get the index of the max value in a NumPy array Method 1 Get Index of Max Value in One Dimensional Array x argmax Method 2 Get Index of Max Value in Each Row of Multi Dimensional Array x argmax axis 1 Method 3 Get Index of Max Value in Each Column of Multi Dimensional Array x argmax axis 0
NumPy s max and maximum Find Extreme Values in Arrays
The NumPy library supports expressive efficient numerical programming in Python Finding extreme values is a very common requirement in data analysis The NumPy max and maximum functions are two examples of how NumPy lets you combine the coding comfort offered by Python with the runtime efficiency you d expect from C
Numpy max NumPy v1 26 Manual, The maximum value of an array along a given axis ignoring any NaNs maximum Element wise maximum of two arrays propagating any NaNs fmax Element wise maximum of two arrays ignoring any NaNs argmax Return the indices of the maximum values nanmin minimum fmin Notes

Finding index of maximum value in array with NumPy
Finding index of maximum value in array with NumPy Viewed 26k times 15 I would like to find a maximum in a float64 array excluding nan values I saw np nanmax function but it doesn t give the index corresponding to the found value it s quite strange to scan after to the value specially the function necessarily use the index Can t it be a mistake searching like that
