how to remove an outside array from numpy array of arrays

Question

I wanted to remove an array outside numpy array of arrays

my current array looks like this:

 array([array([1,2,3],[3,4,5],[34,31,23])])

I want to remove the first array:

array([array([1,2,3],[3,4,5],[34,31,23])])

That isn't exactly what your code produces. The inner `array` is missing a `[]` layer. Also it is awkward to recreate. But you might try `arr[0]`, since it looks like a 1 element object array containing an (3,3) array. — hpaulj, Sep 03 '20 at 06:54
Show the `shape` and `dtype` of this array. What's the source? — hpaulj, Sep 03 '20 at 07:10
shape = (1108,) ; dtype = dtype('O'). Each element is a 768 length numpy array — Nischay Namdev, Sep 03 '20 at 07:14
currently it is of the form: array([array([1.....768],.....,n])]) ; n = 1108 — Nischay Namdev, Sep 03 '20 at 07:19

numpy .toList() function should convert the first array into a list of arrays.

arrayModified = array.toList()

where array variable is the array you want to convert.

You can use np.delete() Read Here

Let arr = array([array([1,2,3],[3,4,5],[34,31,23])])

If you want to delete first array

use arr = np.delete(arr, 0, 0)

first 0 for index and second 0 for axis number

Same result. It is also altering the order of the array elements. – Nischay Namdev Sep 03 '20 at 07:08
