OpenCV 3.2 error : libopencv_video.so.3.2

[slives-lab]

Error results from running colab:

delete files from previous runs of this script

!rm openpose.avi

detect poses in these video frames using OpenPose

!cd openpose && ./build/examples/openpose/openpose.bin --video ../input.mp4 --write_json ./output/ --display 0 --write_video ../openpose.avi

convert the video output result into MP4 so we can visualize it using the 'show_local_mp4_video' function we defined above

!ffmpeg -y -loglevel info -i openpose.avi output.mp4

here is the error

./build/examples/openpose/openpose.bin: error while loading shared libraries: libopencv_video.so.3.2: cannot open shared object file: No such file or directory
