No module named 'generate_dataset'

This error message means that Python is unable to find a module named "generate_dataset". This could occur for several reasons:

1. The module is not installed: If the module is not installed, you can install it using pip. Open a command prompt or terminal and run the command "pip install generate_dataset".

2. The module is installed in a different environment: If you have multiple Python environments installed on your computer, make sure you are using the correct environment where the module is installed.

3. The module is not in the correct directory: If you are trying to import a custom module, make sure that the module is in the correct directory. You can check the current working directory using the command "import os; print(os.getcwd())".

4. The module name is misspelled: Double-check that the module name is spelled correctly in your code.

I hope this helps!
