/home/vsts/work/1/s/hcipy/plotting/animation.py:154: DeprecationWarning: Starting with ImageIO v3 the behavior of this function will switch to that of iio.v3.imread. To keep the current behavior (and make this warning disappear) use `import imageio.v2 as imageio` or call `imageio.v2.imread` directly.
frame = imageio.imread(buf.getvalue())
