This is a somewhat frequent issue on HPC with OpenCV Qt components. A work around is to use specific Qt and OpenCV versions. However in our case cv2 is only used once to encode byte streams (and the function name ('JPG') is confusingly inconsistent with the actual code ('PNG')):

waveorder/waveorder/visual.py

Lines 36 to 40 in 5f60f0a

def array2jpg_bytes(img):
"""encode numpy array in 8-bit jpg bytes"""
is_success, png = cv2.imencode(".png", img)
png = png.tobytes()
return png

And this should be easily swapped out with PIL or similar so that we can stop depending on OpenCV.

Edit: we already depend on pillow (PIL fork) through matplotlib.

from waveorder.
