Unable to import textworld in colab

[rfy1004]

Hi, I'm running the notebook 'Building a simple agent' in colab and have encountered the following ImportError when I tried to import textworld.

/usr/local/lib/python3.10/dist-packages/tatsu/grammars.py in
4 import os
5 import functools
----> 6 from collections import defaultdict, Mapping
7 from copy import copy
8 from itertools import takewhile

ImportError: cannot import name 'Mapping' from 'collections' (/usr/lib/python3.10/collections/init.py)

I tried replacing 'from collections import Mapping' with 'from collections.ac import Mapping' and got this error instead:

/usr/local/lib/python3.10/dist-packages/textworld/envs/wrappers/tw_inform7.py in
91
92
---> 93 class TWInform7(textworld.core.Wrapper):
94 """
95 Wrapper to play Inform7 games generated by TextWorld.

AttributeError: partially initialized module 'textworld' has no attribute 'core' (most likely due to a circular import)

The installation of textworld was sucessfull.

I just realized that it might be because colab updated the main kernel to python 3.10. However I'm still having the same issue in virtual environment using python 3.9.

Hi rfy1004. Did you change the runtime after installing 3.9? You can change it in the Runtime dropdown menu. Eg. for py38

I followed this
https://stackoverflow.com/a/71511943

Also, note that data.zip can now be downloaded from the latest release
https://github.com/microsoft/TextWorld/releases/download/1.5.4/data.zip

Thanks for the solutions for installing Python 3.8. I followed this https://stackoverflow.com/a/71511943 and successfully changed the runtime type to Python 3.8. However when I run import textworld it gives this error:

I tried to manually install glk but got this:

ERROR: No matching distribution found for glk

I figured out that the above error occurred because colab uses libffi.so.8 instead of libffi.so.6. So I tried run this command ! find /usr/lib -name "libffi.so*" linking libffi to version 6. However when I tried to run import textworld again it gave the same attribute error as before:
