error running in train_utils.py and work around

error on running.

got around this by commenting out lines in train_utils.py

    #if use_stitching:
    #    from stitch_wrapper import stitch_rects
    #    acc_rects = stitch_rects(all_rects, tau)
    #else:
    acc_rects = all_rects_r

Looks like a linking error. Have you tried running make again? Or use a different gcc / cython version.

@MarvinTeichmann , I tried running make again. However, it didn't work.

I tried this suggestion as well: https://github.com/Russell91/TensorBox/issues/34. It too didn't work out.
