## LayoutLM for Invoice

### Pre-requirements

Tesseract requires you to install `tesseract-ocr` via `apt` command, just adding it in `packages.txt`.

### Secure

This service is private application, requires user name and password (ref. secret variable `USERNAME` & `PASSWORD`).

```python
def auth(username, password):
    u = os.environ.get('USERNAME')
    p = os.environ.get('PASSWORD')
    return (username == u and password == p)

with gr.Blocks() as demo:
