how to convert a numpy array to a list code example

Example 1: ndarray to list

a = np.array([1, 2])
a.tolist()

Example 2: python numpy array to list

# Basic syntax:
numpy_array.tolist()

# Example usage:
your_array = np.array([[1, 2, 3], [4, 5, 6]])
your_array
--> array([[1, 2, 3],
           [4, 5, 6]])

your_array.tolist()
--> [[1, 2, 3], [4, 5, 6]]

Example 3: convert list to numpy array

import numpy as np
npa = np.asarray(Lists, dtype=np.float32)

Example 4: convert list of lists to numpy array matrix python

x=[[1,2],[1,2,3],[1]]
y=numpy.array([numpy.array(xi) for xi in x])
type(y)
# <type 'numpy.ndarray'>
type(y[0])
# <type 'numpy.ndarray'>
