Cannot run_densecrf.sh

[useebear]

I came across such a problem when run_densecrf.sh, it says:

./run_densecrf.sh: line 70: 9582 Segmentation fault (core dumped) ${CRF_BIN} -id ${IMG_DIR} -fd ${FEATURE_DIR} -sd ${SAVE_DIR} -i ${MAX_ITER} -px ${POS_X_STD} -py ${POS_Y_STD} -pw ${POS_W} -bx ${Bi_X_STD} -by ${Bi_Y_STD} -br ${Bi_R_STD} -bg ${Bi_G_STD} -bb ${Bi_B_STD} -bw ${Bi_W}

Cannot figure out why?

In the densecrf directory, when make, it says in the command window

I encounter the same problem and i don't know how to solve it? have you solved this problem? thank you!

[aurooj]

I encountered the same problem. Did any of you find the solution for this problem?

[Tanzichang]

I have solved this problem now. My problem was that the ppm images was generated incorrectly. And i solved this problem by regenerating the ppm images using the SaveJpgToPPM.m in the following website: https://bitbucket.org/deeplab/deeplab-public/src/26b6af817e4676f6409aa0d609096b31ff72917d/densecrf/my_script/?at=master

Thanks for your reply. Are you using the same features produced from fc8 layer? If yes, then what are the dimensions of your features. I am actually using features produced from RefineNet (109x193x256 for each image) and wanted to run DenseCRF on those, but getting this segmentation fault. I regenerated the PPM files as you mentioned, but it still gives me same error. So, I suspect there is something to do with the features. Any help or hints will be highly appreciated.

[Tanzichang]

Yes, my features are also produced from fc8 layers. I ran the DeepLabv2_VGG16 with the caffe codes and configs provided by this website (http://liangchiehchen.com/projects/DeepLab.html). Thus the input size is 321x321 and the fc8 feature size is 41x41. I think you could try the official codes of DeepLabv2. I hope my reply can help you.

@Tanzichang I encountered the same problem, can you give any suggestions? I'm using python script to convert jpgs to ppms rather than SaveJpgToPPM.m.

[Tanzichang]

@lixiang-ucas I think you could try the official codes of DeepLab, and I encountered several problems when using this project. By the way, I am also a student from UCAS.
