I set NIXPACKS_PYTHON_VERSION to 3.13.5 but it's still using 3.13.0. Is there a way to specify minor version?

Hey, can you try switching the builder to Railpack and set the Python version using one of the ways outlined in the Railpack docs: https://railpack.com/languages/python#versions?

Use major.minor only In Railway Variables set:

NIXPACKS_PYTHON_VERSION=3.13

Redeploy and you’ll get the latest 3.13.x (that’s why 3.13.0 fell back).

If you really need 3.13.5 Switch to a tiny Dockerfile instead of Nixpacks:

FROM python:3.13.5-slim  
WORKDIR /app  
COPY requirements.txt .  
RUN pip install -r requirements.txt  
COPY . .  
CMD ["gunicorn", "myproject.wsgi:application", "--bind", "0.0.0.0:8000"]
