Runtime Error: Size(sourcePtrs) must match size(sourceSizes) and size(scaleInputToNetInputs) #5

Hi! Thank you for your OpenPose ROS wrapper.

I am trying to get this working with a webcam, but I get the following runtime error when I do rosrun openpose_ros openpose_ros_node. My OpenPose installation can run the demo with no problem, and I am using OpenCV 3.2 with ROS Kinetic on Ubuntu 16.04. To get the webcam stream, I have tried using both the usb_cam and cv_camera packages but both give me the same error.

Starting pose estimation demo.
Auto-detecting GPUs... Detected 1 GPU(s), using them all.

Error:
Size(sourcePtrs) must match size(sourceSizes) and size(scaleInputToNetInputs). Currently: 2 vs. 2 vs. 1.

Any ideas why this might be happening?

Thank you!

Hi,

I started to have the same errors after updating OpenPose. After searching a bit, I found that, in openpose_ros/src/openpose_ros_node.cpp from line 99 to 103, there seems to be twice this piece of code:

op::log("Starting thread(s)", op::Priority::High);
opWrapper.start();

Commenting the repetition :

 99    op::log("Starting thread(s)", op::Priority::High);
100    opWrapper.start();
101
102    // op::log("Starting thread(s)", op::Priority::High);
103    // opWrapper.start();

seems to solve the problem (well, it did for me). However, I would be unable to explain in detail why, I'm new to OpenPose and its Wrapper.

Hope this helps :)

AH that worked for me! Thank you so incredibly much, you're a life-saver!
