Quickstart — 5 Minutes

Prerequisites: Docker must be installed (Get Docker)

1. Install Tropiflo

pip install tropiflo

2. Set Your API Token (Required!)

tropiflo set-token --token YOUR_TOKEN  # Get token from your account

IMPORTANT: You must set your token before running tropiflo. Get your token from your account dashboard.

3. Create Your Project Files

Your Python code (xor.py):

from sklearn.pipeline import Pipeline
from sklearn.preprocessing import StandardScaler
from sklearn.linear_model import LogisticRegression
from sklearn.metrics import accuracy_score
import numpy as np

# XOR toy-set
X = np.array([[0,0],[0,1],[1,0],[1,1]])
y = np.array([0,1,1,0])

# CO_DATASCIENTIST_BLOCK_START

pipe = Pipeline([
    ("scale", StandardScaler()),
    ("clf", LogisticRegression(random_state=0))
])

pipe.fit(X, y)
acc = accuracy_score(y, pipe.predict(X))

# CO_DATASCIENTIST_BLOCK_END


print(f"KPI: {acc:.4f}")  # Tag your metric!

# comments
# This is the classic XOR problem — it's not linearly separable!
# A linear model like LogisticRegression can't solve it perfectly,
# because no straight line can separate the classes in 2D.
# This makes it a great test for feature engineering or non-linear models.

Dockerfile:

FROM python:3.10-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
COPY . .
CMD ["python", "xor.py"]

requirements.txt:

scikit-learn
numpy

config.yaml:

mode: "local"       # Required: "local", "gcloud", "aws", or "databricks"
parallel: 3         # Optional: evolve N versions simultaneously

4. Run & Watch It Evolve

tropiflo run --config config.yaml

Tropiflo will build a Docker container, run your baseline, evolve your code over multiple generations, and save best results to co_datascientist_checkpoints/.

Options:

• Add data_volume: "/path/to/data" in config.yaml to mount data
• Use --use-cached-qa to skip questions on repeat runs
• See /docs/ for GCloud, AWS, Databricks configs

---

How It Works

1. Mark code blocks with # CO_DATASCIENTIST_BLOCK_START and # CO_DATASCIENTIST_BLOCK_END
2. Print your KPI: print(f"KPI: {score}")
3. Run: tropiflo run --config config.yaml
4. Deploy: tropiflo deploy co_datascientist_checkpoints/best_X/

---

Data Access Patterns

Option 1: Hardcoded Paths (Simple)

For quick local runs, hardcode data paths directly in your script:

data = np.loadtxt("/full/path/to/my_data.csv")

Option 2: Volume Mounting (Recommended for Docker)

For Docker-based execution, use environment variables with volume mounting:

config.yaml:

mode: "local"
data_volume: "/path/to/your/data"  # Host directory containing data

Your code:

import os
INPUT_URI = os.environ.get("INPUT_URI", "/default/path")
data = pd.read_csv(os.path.join(INPUT_URI, "train.csv"))

When you run with --config config.yaml, Co-DataScientist automatically:

• Mounts your data directory into the Docker container
• Sets the INPUT_URI environment variable
• Your code accesses data without hardcoding paths

Note: Avoid input() or interactive prompts - Co-DataScientist needs to run your code automatically.

🧬 Blocks to evolve

As you will see in the XOR example, Co-DataScientist uses # CO_DATASCIENTIST_BLOCK_START and # CO_DATASCIENTIST_BLOCK_END tags to identify the parts of the system you want it to improve. Make sure to tag parts of your system you care about improving! It will help to Co-DataScientist stay focused on its job.

---

Project Structure

Co-DataScientist supports both single-file scripts and multi-file projects:

• Single File: tropiflo run python my_script.py
• Multi-File: Auto-detects run.sh, main.py, or run.py in your project root
• Custom Entry Point: Just wrap your command: tropiflo run bash custom_script.sh

The system automatically detects which files contain CO_DATASCIENTIST_BLOCK markers and evolves them intelligently.

---

Add Domain-Specific Notes for Best Results

After your code, add comments with any extra context, known issues, or ideas you have about your problem. This helps Co-DataScientist understand your goals and constraints! The Co-Datascientist UNDERSTANDS your problem. It's not just doing a blind search!

---

Multi-File Evolution

When you run Co-DataScientist on a multi-file project:

1. Scanning: It scans all .py files in your project for CO_DATASCIENTIST_BLOCK markers
2. Selection: Each generation, it randomly picks ONE file to evolve
3. Evolution: The AI generates hypotheses and modifies the selected block
4. Stitching: Modified code is integrated back into your full project
5. Testing: Your entire project runs with the new code using your run.sh or custom command
6. Checkpointing: Best results are saved as complete directories with all files

This means you can have complex multi-file ML pipelines where each file evolves independently but is tested as a complete system. Your project structure and dependencies are preserved.

Example Evolution Flow:

Generation 1: Evolve model.py → Test full project → KPI: 30.0
Generation 2: Evolve data_loader.py → Test full project → KPI: 45.0
Generation 3: Evolve main.py → Test full project → KPI: 60.0

Other helpful stuff

Skip Q&A on Repeat Runs

For faster iterations, use cached answers from your previous run:

tropiflo run --use-cached-qa python xor.py

This skips the interactive questions and uses your previous answers, jumping straight to the optimization process.

Deploy Checkpoints to Production

The deploy command makes it easy to take your best checkpoint and create a production-ready project:

# Basic usage - auto-detects original project location
tropiflo deploy co_datascientist_checkpoints/best_6_explore/

# Specify original project path manually
tropiflo deploy best_6_explore/ --original-path /path/to/my_project

# Use custom output directory name
tropiflo deploy best_6_explore/ --output-dir my_optimized_v2

What it does:

1. Copies your entire original project (including data, configs, assets)
2. Integrates the evolved code from the checkpoint
3. Excludes Co-DataScientist artifacts (checkpoints, cache, etc.)
4. Creates a deployment_info.json with checkpoint metadata

The result is a complete, standalone project ready to deploy to production!

We now support Databricks

Databricks setup

1. Download the databricks CLI package

curl -fsSL https://raw.githubusercontent.com/databricks/setup-cli/main/install.sh | sudo sh

2. Get a databricks token : and test the CLI works Get your Databricks token here
3. Prepare a config file with all of your compute/environmental requirements in databricks_config.yaml example below

# Enable Databricks integration
databricks: true

# Databricks configuration for XOR demo
databricks:
  cli: "databricks"  # databricks CLI command (optional, defaults to "databricks")
  volume_uri: "dbfs:/Volumes/workspace/default/volume"  # DBFS volume URI for file uploads
  code_path: "dbfs:/Volumes/workspace/default/volume/xor.py"  # Specific code path (optional, overrides volume_uri + temp filename)
  timeout: "30m"  # Job timeout duration
  
  job:
    name: "run-<script-stem>-<timestamp>"  # Job name template (supports <script-stem> and <timestamp>)
    tasks:
      - task_key: "t"
        spark_python_task:
          python_file: "<remote_path>"  # Will be automatically replaced with actual remote path
        environment_key: "default"
    environments:
      - environment_key: "default"
        spec:
          client: "1"
          dependencies:
            - "scikit-learn>=1.0.0"
            - "numpy>=1.20.0"

Then run the co-datascientist with:

tropiflo run --config databricks_config.yaml

Now your new optimized model checkpoints will save in : dbfs:/Volumes/workspace/default/volume/co-datascientist-checkpoints

Local Docker Execution with Volume Mounting

Run your code in Docker containers locally with automatic data volume mounting. Perfect for reproducible environments and large datasets.

Setup

1. Create a config file (e.g., config.yaml):

mode: "local"
data_volume: "/absolute/path/to/your/data"  # Host directory with your data files
parallel: 1  # Number of parallel executions

2. Update your code to use environment variables:

import os
import pandas as pd

# Co-DataScientist automatically sets INPUT_URI to /data in the container
INPUT_URI = os.environ.get("INPUT_URI")
df = pd.read_csv(os.path.join(INPUT_URI, "train.csv"))

3. Add a Dockerfile to your project:

FROM python:3.10-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
