Thanks for all developer for 3D slicer. Currently, I want to use the semi-automatic segmentation method of 3D slicer in python.

1. Can I install 3D slicer by `pip install slicer`?
2. Which module of 3D slicer is designed for semi-automatic segmentation?

It is appreciated for any suggestion.

Slicer has a Python environment set up and you can install in it any additional Python packages that you need (using the `pip_install()` convenience function). You can find examples of using segmentation tools from Python in the [script repository](https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#How_to_run_segment_editor_effects_from_a_script).
