I believe this is a duplicate of #q149916 (and a few other Q&As). Please see whether that question solves your problem.
If it does, please close yours.

Hi thanks, but actually it's not the same, because it happens when I run the client, not the server, meaning this line: rosrun beginner_tutorials add_two_ints_client.py 1 3. anyway the error path is also different.

Your missing the same thing from your script, namely, the shebang. The path doesn't matter, nor the fact that it's your client (not the server).
