Failed to load module "canberra-gtk-module"

i am trying to run your Demo app, but there are some errors. First of all, the requirements.txt file and the code need updating. For some reason, the Gym specified version can't be install and there are some packages that are missing such as Hydra. Secondly, after I installed my packages, the code can't be run and always show error "Lightning has no attribute LigthtningFlow". This goes the same with LightningApp and LightningWork. Therefore, I re-imported them. After all that, I am still can't run the demo. The UI has poped up, but this is what it returns
