# What does this PR do? This is the second attempt to switch to system packages by default. Now with a hack to detect conda environment - in which case conda image-type is used. Note: Conda will only be used when --image-name is unset *and* CONDA_DEFAULT_ENV is set. This means that users without conda will correctly fall back to using system packages when no --image-* arguments are passed at all. [//]: # (If resolving an issue, uncomment and update the line below) [//]: # (Closes #[issue-number]) ## Test Plan Uses virtualenv: ``` $ llama stack build --template ollama --image-type venv $ llama stack run --image-type venv ~/.llama/distributions/ollama/ollama-run.yaml [...] Using virtual environment: /home/ec2-user/src/llama-stack/schedule/.local [...] ``` Uses system packages (virtualenv already initialized): ``` $ llama stack run ~/.llama/distributions/ollama/ollama-run.yaml [...] INFO 2025-03-27 20:46:22,882 llama_stack.cli.stack.run:142 server: No image type or image name provided. Assuming environment packages. [...] ``` Attempt to run from environment packages without necessary packages installed: ``` $ python -m venv barebones $ . ./barebones/bin/activate $ pip install -e . # to install llama command $ llama stack run ~/.llama/distributions/ollama/ollama-run.yaml [...] ModuleNotFoundError: No module named 'fastapi' ``` ^ failed as expected because the environment doesn't have necessary packages installed. Now install some packages in the new environment: ``` $ pip install fastapi opentelemetry-api opentelemetry-sdk opentelemetry-exporter-otlp aiosqlite ollama openai datasets faiss-cpu mcp autoevals $ llama stack run ~/.llama/distributions/ollama/ollama-run.yaml [...] Uvicorn running on http://['::', '0.0.0.0']:8321 (Press CTRL+C to quit) ``` Now see if setting CONDA_DEFAULT_ENV will change what happens by default: ``` $ export CONDA_DEFAULT_ENV=base $ llama stack run ~/.llama/distributions/ollama/ollama-run.yaml [...] Using conda environment: base Conda environment base does not exist.
