Hello good afternoon, I am getting this error in Section 2.1: Generating the Dataset:

Hi @Carlos_Merino, it looks like there is an issue in your generator functions. Can you send me your notebook via DM so I can take a look at your implementation?

Hi @Carlos_Merino, the issue is in the uniform_generator function, notice how the output of this cell does not match the expected output. You don’t need the default_rng() you defined in there. If you take it away, the rest of the code works normally.

thank you now it works fine

@Carlos_Merino, could you edit the post where you shared your notebook and delete your notebook so the answers are not leaked? In the future please share your notebook via a private message :slight_smile:

how do you private message?

You click on an user’s name and it should prompt you the option to message that user
