# Failure Archive Entry

## Issue
|
|
CLI commands failed with `ModuleNotFoundError: No module named 'numpy'` (and similar for `pandas`, `aiohttp`, `fastapi`, `uvicorn`).
|
|
|
|
## Attempt
|
|
Multiple attempts to run CLI commands after sibling branch integration; observed import errors when commands tried to load service modules.
|
|
|
|
## Approach
|
|
Initially attempted to fix by adjusting `PYTHONPATH` manually and creating a virtualenv. Discovered that the CLI virtualenv did not include required scientific and web dependencies.
|
|
|
|
## Root Cause
|
|
The `aitbc-cli` package in `pyproject.toml` did not declare dependencies that the service modules require. The coordinator-api services import `numpy`, `pandas`, `aiohttp`, `fastapi`, and `uvicorn`, but these were not listed under the CLI package's dependencies, leading to import failures when the CLI imported service modules.
|
|
|
|
## Resolution
|
|
Added the following to root `pyproject.toml` dependencies:
|
|
```toml
|
|
numpy>=1.26.0
|
|
pandas>=2.0.0
|
|
aiohttp>=3.9.0
|
|
fastapi>=0.111.0
|
|
uvicorn[standard]>=0.30.0
|
|
```
|
|
Then reinstalled the CLI in editable mode: `pip install -e ./cli`.
|
|
|
|
## Useful Artifacts
|
|
- The list of required packages is now part of the canonical dependency set.
|
|
- The fix allowed all CLI commands (`surveillance`, `ai_trading`, `advanced_analytics`, `regulatory`, `compliance`, `ai_surveillance`) to load successfully.
|
|
|
|
## Prevention
|
|
- Keep shared dependencies in a central `pyproject.toml` that covers both services and CLI.
|
|
- Implement an import test in CI that verifies CLI commands can import without error.
