How to install the dependency in evaluator?

[codelion]

just install it in the same virtual env you are running the openevolve. Many of the examples have their own requirements.txt for this purpose e.g. https://github.com/codelion/openevolve/blob/main/examples/function_minimization/requirements.txt

What I do for complex dependencies is to install them in another virutal environment, and use subprocess to run the new venv's python in a separate process, passing the results by outputting a JSON to stdout. I find it keeps things simpler, especially when working with existing code that define the problem space.
