出现这个问题，发现需要库

但是这个库在databases中，而我们运行的主代码在scripts


会发现无法导入，如何导入
参考：https://github.com/vegesm/pose_refinement/issues/2

if you are using the terminal
PYTHONPATH=. python scripts/predict.py -r video.mp4 output.pkl

(my preferred way) in your IDE select the source files:
for example in PyCharm
In File/Settings/Project: (name)/Project Structure/ right mouse click on src and mark it as a source (it will turn blue)

在pycharm中的project中直接改即可。
