…n-features-bug Fix bug with predictions in RTrees/Boost * address bug where predict functions with invalid feature count in rtrees/boost models * compact matrix rep in tests * check 1..n-1 and n+1 in feature size validation test
Currently, the LOADER_DIR is set as os.path.dirname(os.path.abspath(__file__)). This does not point to the true library path if the cv2 folder is symlinked into the Python package directory such that importing cv2 under Python fails. The proposed change only resolves symbolic links correctly by calling os.path.realpath(__file__) first and does not change anything if __file__ contains no symbolic link.
