@NH102 in this case, that will be the smallest amount of code that produces the error. Is it one library statement? Two? More? Does the error not happen until you try to import data? You may need to run line-by-line to figure this out.
If the error only happens when you are importing data from somewhere on your computer, then it won’t be possible to make an entirely reproducible example, but seeing the code may still help.
It will also help to see the entire error message in the context in which it occurs (it’s usually a bit surprising for people to learn that error messages on their own aren’t often very useful! It’s the error plus the code that triggered it that starts to give you clues).
