Make prompt-toolkit an optional dependency. #162

Closed MarcCote closed 4 years ago

MarcCote commented 5 years ago

Some systems (e.g. Google Colab) might have an old version of prompt-toolkit (TextWorld needs prompt_toolkit<2.1.0,>=2.0.0). Since that library is not essential to use TextWorld, I think it would be better to make it an optional dependency.

While we are looking for a proper solution, @krispymelody you can use pip install https://github.com/MarcCote/TextWorld/archive/fix_162.zip which will only install the bare minimum. Since Google Colab already as some (older) libraries installed (e.g. gym, pillow, prompt-toolkit), it seems to be working fine except for visualization modules (mainly used for debugging).
