Prerequisites and system recommendations
Python 3.11 or 3.12 is required to use Meridian.
We also recommend using a minimum of 1 GPU.
Install
To install Meridian, run the following command to automatically install the most
recent published version from PyPI.
Linux (GPU)
python3-mpipinstall--upgrade'google-meridian[and-cuda]'# Verify the installation:python3-c"import meridian; print(meridian.__version__)"
macOS
python3-mpipinstall--upgrade'google-meridian'# Verify the installation:python3-c"import meridian; print(meridian.__version__)"
CPU
python3-mpipinstall--upgrade'google-meridian'# Verify the installation:python3-c"import meridian; print(meridian.__version__)"
Latest

# Verify the installation:python3-c"import meridian; print(meridian.__version__)"
How to use the Meridian library
You can run the Meridian code programmatically using sample data with
the Getting started colab.
The Meridian model uses a holistic MCMC sampling approach called
No U Turn Sampler (NUTS)
which can be compute intensive. To help with this, GPU support has been
developed across the library (out-of-the-box) using tensors. We recommend
runningyour Meridian model on GPUs to get real time optimization results and
significantly reduce training time.

Installation via `pip` uses: `python3 -m pip install --upgrade 'google-meridian[and-cuda]'` (Linux/GPU), `google-meridian` (macOS/CPU). CPU-only install also uses `google-meridian`. To verify the install, run: `python3 -c \"import meridian; print(meridian.__version__)\"`. The library, which uses No U-Turn Sampler, is compute-intensive, thus GPU usage is recommended for real-time optimization and faster training.\n"]]
