⛏️ Installation

Tip

Use uv for installation — it's faster and more reliable than pip.

For Development

# Create and activate a conda environment
conda create -n EvoSci python=3.11 -y
conda activate EvoSci

# Install in development (editable) mode
pip install EvoScientist
# or
pip install -e .

Option 1:

Install the latest version directly from GitHub for quick setup:

TODO

Option 2:

If you plan to modify the code or contribute to the project, you can clone the repository and install it in editable mode:

🔄 Upgrade to the latest code base

git pull
uv pip install -e .

⚡ Quick Start

CLI Inference

You can perform inference directly from the command line using our CLI tool:

python -m EvoScientist

Optional arguments:

Script Inference

from EvoScientist import EvoScientist_agent
from langchain_core.messages import HumanMessage
from EvoScientist.utils import format_messages

thread = {"configurable": {"thread_id": "1"}}
question = "Hi?"
last_len = 0

for state in EvoScientist_agent.stream(
    {"messages": [HumanMessage(content=question)]},
    config=thread,
    stream_mode="values",
):
    msgs = state["messages"]
    if len(msgs) > last_len:
        format_messages(msgs[last_len:]) 
        last_len = len(msgs)
