Attempt to free invalid pointer. Abort trap: 6

[shikha4444]

After setting up toolbox using the instructions in the end I am getting below error. Working on Mac OS x sierra 10.12.3 with CPU only.

I0326 18:17:51.248069 3768251328 net.cpp:804] Ignoring source layer data

If you're still getting this error, I would make sure you are compiling Caffe and OpenCV correctly. In particular, I'd recommend making sure you're using the same version of the library at run time (via your LD_LIBRARY_PATH) as at compile time.

Closing for now.

Apologies if I'm missing something but I've tried this install on a two of my Macs to no avail and still have the same issue. Note, I didn't set the LD_LIBRARY_PATH per the Caffe instructions and caffe works CPU only.

Actually, I solved this as it appears there a few conflicts that could be resolved via:

• Per the Caffe OSX Installation Instructions, when installing opencv you may want to install using the flag --without-numpy so it uses the numpy that is installed via pip instead of installing of having brew install another copy of numpy.
• If you're using CPU-only, you may also want to use the flag --without-opencl when installing opencv.
• Within the Deep Visualization Toolbox instructions, if you already have scipy installed via pip, you may want so skip the step to install scipy via brew.
• Even after all of this, the order of the imports may still result in an Abort trap: 6 error. For example, running the imports in this order:

import numpy as np
import matplotlib.pyplot as plt
from PIL import Image
import caffe

resulted in the error:
>>> src/tcmalloc.cc:283] Attempt to free invalid pointer 0x7ff514a70e80 Abort trap: 6

But if you were to re-order them per below, then everything works.

import numpy as np
import caffe
import matplotlib.pyplot as plt
from PIL import Image

Thus, you may need to update the run_toolbox.py file so that the top of it has:

# added this to avoid "Abort Trap 6" error
import numpy as np
import caffe
import cv2
import scipy
import skimage
# added this to avoid "Abort Trap 6" error

Thanks a lot it is working now.
