Error while data generation

[SExpert12]

Hi,
When I run the file for data generation I got this error.
sh datagen.sh

File "leaderboard/scripts/run_evaluation.py", line 20
print(f'Save gifs: {cfg_org.save_explainability_viz}')
^
SyntaxError: invalid syntax
File "leaderboard/scripts/run_evaluation.py", line 20
print(f'Save gifs: {cfg_org.save_explainability_viz}')

^
SyntaxError: invalid syntax
File "leaderboard/scripts/run_evaluation.py", line 20
print(f'Save gifs: {cfg_org.save_explainability_viz}')

How to resolve this?
Thanks.
