Got so many errors, but why raw input? and also can't decode 0xe7 in utf-8 codec

[GhostOps77]

When I ran this code in Google colab, i got this error
How would I solve this? any ideas?
I dont know anything about ML and TF though

I just cloned the repository and ran the below code in colab:

%cd /content/
%cd /content/im2latex-tensorflow/im2markup

!python scripts/preprocessing/preprocess_images.py --input-dir ../formula_images --output-dir ../images_processed
!python scripts/preprocessing/preprocess_formulas.py --mode normalize --input-file ../im2latex_formulas.lst --output-file formulas.norm.lst

!python scripts/preprocessing/preprocess_filter.py --filter --image-dir ../images_processed --label-path formulas.norm.lst --data-
path ../im2latex_train.lst --output-path train.lst
!python scripts/preprocessing/preprocess_filter.py --filter --image-dir ../images_processed --label-path formulas.norm.lst --data-
path ../im2latex_validate.lst --output-path validate.lst
!python scripts/preprocessing/preprocess_filter.py --no-filter --image-dir ../images_processed --label-path formulas.norm.lst 
--data-path ../im2latex_test.lst --output-path test.lst
!python scripts/preprocessing/generate_latex_vocab.py --data-path train.lst --label-path formulas.norm.lst --output-file 
latex_vocab.txt

!python /content/attention.py

Output:
