Oups what is going wrong?

I want to retrieve the ids of a number of people, stored in the authors.csv file. I modified the name of path_csv and thought it would work. But it doesn't. It's late and I'm not sure I can solve this problem. If you have a clue, could you tell me? Here is the answer I get:
