Chris is right I think - the error probably comes from your line:

`aleph` is an array, but that Nilearn function expects a "Niimg-like
object" not an array:

https://nilearn.github.io/stable/modules/generated/nilearn.plotting.plot_img.html#nilearn.plotting.plot_img

https://nilearn.github.io/dev/manipulating_images/input_output.html

But, as a meta-point - I highly recommend this article about asking
good questions.  In particular - please remember that we are all
volunteers, and most of us are very busy - so we very much appreciate
it when you show us you've investigated fairly carefully already, and
what you've tried:
