Execution error when saving JSON and no people is detected about openpose HOT 9 CLOSED

I remember this bug (it is not the fading to white, but the 1st instant in which no people appear), but it was solved at some point.

Can you git pull or re-download the latest version of the library and re-compile it?

To re-compile it in case you just do git pull:
make clean && cd 3rdparty/caffe && make clean && make distribute -j8 && cd ../.. && make all -j8

In case you re-download it, just delete the old version and follow the installation steps again.

Note the change rtpose.bin --> openpose.bin

Let me know if it still fails!

from openpose.

Mmm.. I did git pull and re-compile openpose.
And check commit log.

# git log --oneline
f4dd473 Fixed bug: disable_blending not working
f3454e3 Updated Caffe & more demo doc
...

And I run following command. But same error has occured.

# ./build/examples/openpose/openpose.bin --video sozai/notall2.mp4 --write_pose j

OK then it is something else, but I tried that video and it worked for me. So I few thoughts:

1. Could you convert that video to standard avi format and try it? Or can you send me a link (Dropbox, Google Drive, etc.) to your exact video? Maybe it is some kind of unsupported codecs.
2. Which version of OpenCV are you using? The one from apt-get or a custom build? If it is a custom build, which exact version?
3. Could you try on a different video where there is no people on the scene? So I can to know if the error is when no people is there or if it is just this video.
   Sorry for any inconveniences!

These days I can't reproduce this issue.
Sorry, I might have mistaken something maybe m(_ _)m

I received the same error when using the wrapper. I wrote a user-input class that reads image paths and crop positions from a csv file and applies the given cropping to the image. It then resizes the image into 656*358. The image is then put into an input-datum.
I followed the asynchronous user code example.
In particular the cropped and resized image is a relatively low-resolution of a pedestrian walking away from the camera, so I can imagine that the issue may be related to the network not a person in the image. Is there something that should be added into the user-input class to avoid this runtime error? It occurs in function opWrapper.waitAndEmplace(datumToProcess). Could I simply assume that this means that no people were detected?

The error is not present in the demo.

Good catch! It actually happened when Array was empty (e.g. if no keypoints are detected). Fixed in my last commit, it will give you an empty cv::Mat if Array.empty() == true. (I did not handled this situation before).

Please, post again if the error still persists.

Hello! I met the same error.when I run this command:
./build/examples/openpose/openpose.bin -image_dir /path/to/image/ -write_pose /path/to/save/ -write_pose_format xml -scale_mode 0 -no_display ture

It is because in some images the demo can’t detect people. But I don't want that the demo to be aborted. I hope it can still run ,and output a xml say there is nobady in the image. How should I change the demo?

@nikoong Please, try write_pose_json and let me know if it works instead. Thanks

@gineshidalgo99 Thank you！It works.
