Converting list to numpy array

Question

I have managed to load images in a folder using the command line sklearn: load_sample_images()

I would now like to convert it to a numpy.ndarray

Answer 1

If you have a list of lists, you only needed to use ...

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

per this LINK in the scipy / numpy documentation. You just needed to define dtype inside the call to asarray.
