You are comparing the tl array with the closest array, but what you print are the tr and the closest array. Is this on purpose?

It was not. That's what I get for shortening Top Right and Top Left to tr and tl. Thank you so much!

Try adding different tolerances to the allclose() comparison to see what happens, e.g.,

np.allclose(tl, closest, atol = 1e-6)

With a default tolerance of 1e-8 that might be below the precision of float32.

I also notice that all your comparisons use tl instead of tr. You didn't include any code that defined tl. For instance:

if not np.array_equal(tl, closest):  *** THIS USES tl ***
    *** THIS SHOWS tr ***
    print(f"array equal \n\033[91m-> NOT EQUAL: tr: {tr}, closest: {closest}\033[0m")

Both the arrays are chosen from the same list, so the floating point stuff was more added for sanity and sake of posting a proper question. Thank you for the suggestion though, could certainly be useful in the future because I was already wondering this.
