Issue with installed font

I’m trying to install a font (Atlas Typewrite). When I run
from matplotlib import font_manager
font_manager.findSystemFonts(fontpaths=None, fontext=“ttf”)

it shows up in the list of fonts

‘/Users/gracecolverd/Library/Fonts/AtlasTypewriter-Regular.ttf’,

but when i run

font_manager.findfont(‘Atlas Typewriter’)

I get

findfont: Font family [‘Atlas Typewriter Regular’] not found. Falling back to DejaVu Sans.
