+# If you google, you find lots of changes of opencv between 4.6 and 4.10, e.g. ArUco changes that affect our calibration.
+# So, for now, until scikit-surgerycalibration Issue #48 is fixed, so that we can upgrade to
+# opencv-contrib-python-headless >= 4.10.0.84 and beyond, numpy must be restricted to <2.0.
