Fix NotFoundError

✅ Solution

The "NotFoundError" in anthropic-sdk often arises from incorrect package installation or version conflicts, preventing the program from locating necessary modules or attributes. Ensure that the anthropic-sdk is correctly installed (`pip install anthropic --upgrade`) and that its version aligns with the code's requirements, checking for potential conflicts with other installed packages. Downgrading or upgrading anthropic-sdk to a compatible version might also be necessary.
