Cannot import DocumentFile

[ttrungtin2910]

Hi there, I'm starting to use doctr. In the first step, I am using Ubuntu 20.04, When I import the library but the program show this problem:
cannot load library 'gobject-2.0-0': gobject-2.0-0: cannot open shared object file: No such file or directory. Additionally, ctypes.util.find_library() did not manage to locate a library called 'gobject-2.0-0'
I do the same in Windows, It got no problem. Please help me

Thanks
