Openpose: Segmentation fault (core dumped) when json file generation

[miraikeshiki]

Issue summary

Get "Segmentation fault (core dumped)" when trying to output the json file.

Executed command (if any)

./build/examples/openpose/openpose.bin --video 1.avi --no_display true --write_video result.avi --write_keypoint_json a.json --face --keypoint_scale 3

I also tried
sudo ./build/examples/openpose/openpose.bin --video 1.avi --no_display true --write_video result.avi --write_keypoint_json a.json --face --keypoint_scale 3
The error is gone, but it still doesn't work.

But
./build/examples/openpose/openpose.bin --video 1.avi --no_display true --write_video result.avi --write_coco_json a.json --face --keypoint_scale 3
works perfect.

OpenPose output (if any)

I don't know why but when I deleted all codes in op::mkdir(), it works fine...

[gineshidalgo99]

Hi, I use the boost library for mkdir(). So I think it should be either of these problems:
1) You are trying to create a dir in a protected folder (e.g. /usr/local/), but I tried that and it did not crash, so I do not think this is the problem (just to make sure this is not the problem, you can try running the demo with sudo.
2) Remove boost and re-install it again. After re-installing it, you will have to remove (or re-compile) and re-install OpenPose too.
Let me know whether and which one works!

[miraikeshiki]

Running the demo with sudo doesn't help, just hides the error, but re-installing boost works.
Thanks!

[miraikeshiki]

I get Segmentation fault again without doing anything, just re-compiled OpenPose, and re-installing boost doesn't work this time...

[gineshidalgo99]

Is the same function? It is definitively something to do with boost, someone posted in the past that compiling boost from scratch (instead of the apt-get version) worked for him (and re-compiling OpenPose/Caffe)

[miraikeshiki]

But didn't work for me...
The same function, and op::getFilesOnDirectory, and op::exist (directoryPath="images/")...

[gineshidalgo99]

OK thank you for the feed-back, all of those functions use boost... So far I have no more idea how to fix it other than what other people said about re-compiling boost. Please post (you or anyone) if you find a solution for that problem. I will try to look something else but I cannot test it myself since it is working on my devices, so no idea how to debug it from here...

for arch distributions, installing py++ from AUR may resolve the seg fault after build issue: pacman -S py++ https://aur.archlinux.org/packages/py%2B%2B/

Same issue..

Hi @miraikeshiki , how did you solve this problem? I am having the same and I tried everything suggested on the posts (rebuild boost, rebuild opencv etc) multiple times but the outcome is always the same.
