This is very dangerous. It will replace any tt. with at., regardless of where in the line, tt is found. It should somehow have a lookbehind that checks if tt was not preceded by a letter, underscore or a dot. From the little I know of sed, I think that it doesn't support look around conditions (see here)

"s/pm\.sample()/pm.sample(return_inferencedata=False)/g"
"s/, return_inferencedata\=True//g"
"s/return_inferencedata\=True, //g"
"s/return_inferencedata\=True//g"
)

for replace in "${replace_strings[@]}"; do
find $1 -name "*.ipynb" -type f -exec sed -i -e "$replace" {} \;
find $1 -name "*.py" -type f -exec sed -i -e "$replace" {} \;
