ok now its working, its explicitly using the conda environment now which it wasnt before. Maybe just an agent mistake before...

i have some rate limiting on top of it so the connection / tests are a bit unstable

Reasoning: The build is failing due to compatibility issues between the Python version and the old scikit-learn version. However, since Pipeline is pure Python, I can bypass the __check_build by directly importing from the module file. Let me try a different approach - I can bypass the check_build import or directly test the pipeline module. Actually, let me just look at the pipeline.py file directly. Since this is a pure Python file, I don't need to build the entire project to make my changes. I can: 1. Read and understand the pipeline.py file 2. Make the changes 3. Test by directly importing just the pipeline module Let me also check if there's a way to bypass the check_build.
