ImportError troubleshooting steps

python3 app.py Traceback (most recent call last): File "/Users/danielkliewer/mddb02/app.py", line 9, in <module> from vector_database import ( ...<5 lines>... ) ImportError: cannot import name 'initialize_chroma_db' from 'vector_database' (/Users/danielkliewer/md db02/vector_database.py)

The error: ``` ImportError: cannot import name 'initialize_chroma_db' from 'vector_database' ``` means that Python tried to import `initialize_chroma_db` from `vector_database.py`, but that function doesn't exist (or isn't visible) in that file. ### Here's how to fix it: #### ✅ Step 1: Open `vector_database.py` Check that the function `initialize_chroma_db` is: - **Defined** in that file - **Not misspelled** - **Not commented out** - **Not inside an `if __name__ == "__main__":` block** Example of correct function definition: ```python # vector_database.py def initialize_chroma_db(): # your implementation here pass ``` #### ✅ Step 2: Ensure it's exported (nothing special needed in Python if it's just a function) Just make sure it's not conditionally hidden or private. #### ✅ Step 3: Restart the app after changes ### 🛠️ If `initialize_chroma_db` is defined but still not found: - Make sure there's no circular import (e.g., `vector_database.py` is importing from `app.py`) - Ensure `vector_database.py` is not a folder or module with the same name that’s masking the file - You can print debug info to see what `vector_database` resolves to: Add this above the import line in `app.py`: ```python import vector_database print(vector_database.__file__) ``` This will show what file Python is really importing from. --- If you'd like, paste the contents of `vector_database.py` and your import line from `app.py`, and I can tell you exactly what's wrong.
