Why isn't Pyinotify able to watch a dir?

I would like Pyinotify to watch a templates directory, which has subfolders, but I'm getting this error: 

DIRECTORY /home/project/templates
[Pyinotify ERROR] add_watch: cannot watch /home/project/templates WD=-1
[Pyinotify ERROR] add_watch: cannot watch /home/project/templates/dir1 WD=-1
[Pyinotify ERROR] add_watch: cannot watch /home/project/templates/dir2 WD=-1
Waiting for stuff to happen...

I've found answers such as using a unicode directory name or using other programs which use inotify, but each is too specific.

What generally causes this error?

Increase the maximum number or watches: 

sudo sysctl -n -w fs.inotify.max_user_watches=16384
