Create and Activate Environment

Option 1: Using uv (Recommended)

uv is a fast Python package and environment manager.

1. Install uv (if not already installed)

curl -LsSf https://astral.sh/uv/install.sh | sh

Restart your terminal after installation.

2. Create the virtual environment

uv venv .venv

3. Activate the environment

# macOS / Linux
source .venv/bin/activate
# Windows (PowerShell)
.venv\Scripts\Activate.ps1

4. Install dependencies (from lock file)

uv sync

This installs exact, reproducible versions from uv.lock.

---

Option 2: Using pip

Use this if you don’t want to install uv.

1. Create the virtual environment

python -m venv .venv

2. Activate the environment

# macOS / Linux
source .venv/bin/activate
# Windows (PowerShell)
.venv\Scripts\Activate.ps1

3. Upgrade core tooling

python -m pip install --upgrade pip setuptools wheel

4. Install dependencies

pip install -r requirements.txt

---

Verify Installation

python --version
pip list

---

Deactivate the environment

deactivate

Run the app

source .venv/bin/activate
python app.py

Run a single test

For example for test_files_api_info_generation

python -m pytest tests/document_processor/file_upload.py::test_files_api_info_generation
