An error while running the demo code

[yangchihyuan]

Hi, I run the demo file xfeat.sh but got an error. Is there any suggestion to prevent the error? Thanks a lot.

Sorry for the late reply. Just back from my trip. Have you solved your problem already?

[yangchihyuan]

Thank you for the reply. I didn't solve the problem yet because although the program crashes, it still generates 4 prob files.

[zhengshou]

It seems not straightforward for me to interpret your error according to this log file. Have you run C3D feature extraction successfully before? If not, could you please first get familiar with C3D usage because my pipeline and settings are based on and thus quite similar with C3D.

[yangchihyuan]

Thank you for the suggestions. I will do it later. By the way, after rebuilding caffe and CDC, the error message changes to Error in `../CDC/build/tools/extract_image_features.bin': double free or corruption (!prev): 0x00000000010fa1e0 For your information.

[zhengshou]

Closing this issue since no further update. For issues related with C3D, please direct to C3D github repo. Thanks.
