Error: No module named 'Cython'

Good day,

I am trying to install the updated repository. In REPRODUCE_RESULTS.md, I have cloned the repository using git clone https://github.com/minerva-ml/open-solution-mapping-challenge.git and tried to install the conda environment mapping.

Command used is conda env create -f environment.yml

Terminal shows:

Collecting pycocotools==2.0.0 (from -r /home/deankarlo/Thesis Files/ML Models/open-solution-mapping-challenge/condaenv.aog2chrg.requirements.txt (line 16))

CondaValueError: pip returned an error

When installing pycocotools it seems to be looking for Cython.

Not sure if there is any difference in the dependencies but it fixed the pycocotools errors for me.
