Error running code about facer

[johnwmillr]

Hmm, nothing immediately jumps out to me. Can you put in a print statement to figure out which image file its failing on? Is there something that makes that image different from the rest? Does the error go away if you remove the file?

Thanks for the quick response. I through in a try/except and print statement to try to figure out what is going on. Here is my code for facer.py:

    # Delaunay triangulation
        rect = (0, 0, w, h)
        try:
            dt = calculateDelaunayTriangles(rect, np.array(pointsAvg))

            # Warp input images to average image landmarks
            output = np.zeros((h, w, 3), np.float32())
            for i in range(0, len(imagesNorm)):
                img = np.zeros((h, w, 3), np.float32())
                # Transform triangles one by one
                for j in range(0, len(dt)):
                    tin, tout = [], []

                    for k in range(0, 3):
                        pIn = pointsNorm[i][dt[j][k]]
                        pIn = constrainPoint(pIn, w, h)

                        pOut = pointsAvg[dt[j][k]]
                        pOut = constrainPoint(pOut, w, h)

                        tin.append(pIn)
                        tout.append(pOut)
                    img = warpTriangle(imagesNorm[i], img, tin, tout)
                if return_intermediates:
                    incremental.append((output + img) / (i + 1))


                # Add image intensities for averaging
                output = output + img

            # Divide by num_images to get average
            output = output / num_images

            if return_intermediates:
                warped.append(img_affine)
        except:
            print('skipping broken frame...')
            pass
    incremental = incremental[-num_images:]
    print('Done.')

This gave me:

Segmentation fault: 11

It seems like there was something fishy with the images (though they looked fine to me and had landmarks predicted).

Unfortunately, python crashes after the Done. print statement with segmentation fault 11. Have you come across this?

Thanks again!

FYI it worked. Not sure why. Maybe my machine was running too much before and could handle the load. Thanks!

Glad to hear you've got it working. Good luck with your project!
