Python 3.11 Recommended for nano-vllm | Generated by AI

Home 2026.07

For this project (nano-vllm), the pyproject.toml defines:

requires-python = ">=3.10,<3.13"

So valid choices are Python 3.10, 3.11, or 3.12.

Recommendation: Python 3.11

Here’s why:

Factor 3.11 3.12
triton support ✅ Excellent, widely tested Good, but some edge cases historically
torch compatibility ✅ Fully supported Supported
CUDA graph stability ✅ Most battle-tested Fine, but newer
Package ecosystem ✅ Maximum compatibility for ML Some packages were late to support

Since this project depends on triton>=3.0.0 and torch>=2.4.0 and uses CUDA graphs + tensor parallelism (GPU-centric ML), Python 3.11 is the safest, most battle-tested choice.

How to set it in Zed

  1. Open Command Palette (Cmd+Shift+P)
  2. Run “Zed: Select Python Environment”
  3. Choose your Python 3.11 interpreter

Or create a .python-version file at the project root:

echo "3.11" > /mnt/data/nano-vllm/.python-version

Then select that venv/interpreter in Zed.
