Installing Bodo Community Edition¶

Bodo is available as a Python package on pip, and can be installed as follows:

pip install bodo

Bodo can also be installed as a using the conda command (see how to install conda below). If you are installing bodo through conda, we recommend creating a conda environment and installing Bodo and its dependencies in it as shown below:

conda create -n Bodo python=3.9 -c conda-forge
conda activate Bodo
conda install bodo -c bodo.ai -c conda-forge

Bodo uses MPI for parallelization, which is automatically installed as part of the conda install command above. This command installs Bodo Community Edition by default, which is free and works on up to 8 cores. For information on Bodo Enterprise Edition and pricing, please contact us.

How to Install Conda¶

Install Conda using the instructions below.

On Linux¶

wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh -O miniconda.sh
chmod +x miniconda.sh
./miniconda.sh -b
export PATH=$HOME/miniconda3/bin:$PATH

On MacOS¶

curl https://repo.continuum.io/miniconda/Miniconda3-latest-MacOSX-x86_64.sh -L -o miniconda.sh
chmod +x miniconda.sh
./miniconda.sh -b
export PATH=$HOME/miniconda3/bin:$PATH

On Windows¶

start /wait "" Miniconda3-latest-Windows-x86_64.exe /InstallationType=JustMe /RegisterPython=0 /S /D=%UserProfile%\Miniconda3

Open the Anaconda Prompt to use Bodo (click Start, select Anaconda Prompt). You may use other terminals if you have already added Anaconda to your PATH.

Optional Dependencies¶

Some Bodo functionality may require other dependencies, as summarized in the table below. All optional dependencies except Hadoop can be installed using the commands

conda install gcsfs sqlalchemy snowflake-connector-python hdf5='*=*mpich*' openjdk -c conda-forge

and

pip install deltalake

Functionality	Dependency
`pd.read_sql / df.to_sql`	`sqlalchemy`
`Snowflake I/O`	`snowflake-connector-python`
`GCS I/O`	`gcsfs`
`Delta Lake`	`deltalake`
`HDFS or ADLS Gen2`	hadoop (only the Hadoop client is needed)
`HDF5`	`hdf5 (MPI version)`

Testing your Installation¶

Once you have activated your conda environment and installed Bodo in it, you can test it using the example program below. This program has two functions:

The function gen_data creates a sample dataset with 20,000 rows and writes to a parquet file called example1.pq.
The function test reads example1.pq and performs multiple computations on it.

import bodo
import pandas as pd
import numpy as np
import time

@bodo.jit
def gen_data():
    NUM_GROUPS = 30
    NUM_ROWS = 20_000_000
    df = pd.DataFrame({
        "A": np.arange(NUM_ROWS) % NUM_GROUPS,
        "B": np.arange(NUM_ROWS)
    })
    df.to_parquet("example1.pq")

@bodo.jit
def test():
    df = pd.read_parquet("example1.pq")
    t0 = time.time()
    df2 = df.groupby("A")["B"].agg(
        (lambda a: (a==1).sum(), lambda a: (a==2).sum(), lambda a: (a==3).sum())
    )
    m = df2.mean()
    print("Result:", m, "\nCompute time:", time.time() - t0, "secs")

gen_data()
test()

Save this code in a file called example.py, and run it on a single core as follows:

python example.py

Alternatively, to run the code on four cores, you can use mpiexec:

mpiexec -n 8 python example.py

Note

You may need to delete example1.pq between consecutive runs.
