Explanation:
The most efficient and reliable approach is to include a requirements.txt file in the notebook directory and share the entire directory. This method specifies all necessary libraries and their versions, allowing the colleague to install them using pip install -r requirements.txt. This ensures a consistent and reproducible environment, minimizing setup and dependency issues. Other options either rely on the colleague having pre-installed libraries (which is impractical and error-prone), export the notebook without dependencies (requiring manual library installation), or use DBC files that embed dependencies within the notebook, making them large and difficult to manage.
