Alternatively, we provide a python script with full command line configurability. You can also find the XGB-186-CLICKS-DASK Notebook on GitHub. Later on, we will talk about some advanced optimizations including UCX and spilling. Multi-GPU training walkthroughįirst, I’ll walk through a multi-GPU training notebook for the Otto dataset and cover the steps to make it work. XGBoost in the rapidsai channel is built with the RMM plug-in enabled and delivers the best performance regarding multi-GPU training. A quick way to verify the correctness of the XGBoost version is mamba list xgboost and check the “channel” of the xgboost, which should be “rapidsai” or “rapidsai-nightly”. Instead, use the XGBoost installed from RAPIDS. The error message will read something like the following:Įxception: “XGBoostError(‘ /opt/conda/conda-bld/work/rabit/include/rabit/internal/utils.h:86: Allreduce failed’)” Manually updating or installing XGBoost using pip or conda-forge is problematic when training XGBoost together with UCX. Some users might notice that the version of XGBoost is not the latest, which is 1.7.5.

Install the correct XGBoost whose channel should be rapidsai or rapidsai-nightly Avoid manual updates for XGBoost In particular, you’ll want to check the XGBoost library installed using the command: This instruction installs all the libraries required including Dask, Dask-cuDF, XGBoost, and more. This post uses version 23.04, which can be installed with the following command: mamba create -n rapids-23.04 -c rapidsai -c conda-forge -c nvidia \ You can find up-to-date install instructions in the RAPIDS Installation Guide.
Install the latest RAPIDS versionĪs a best practice, always install the latest RAPIDS libraries available to use the latest features. Specifically, I opted for a fresh installation of mamba. Mamba provides similar functionalities as conda but is much faster, especially for dependency resolution. For this guide, I recommend using Mamba, while adhering to the conda install instructions.

It’s critical to note that there are several ways to install these libraries-pip, conda, docker, and building from source, each compatible with Linux and Windows Subsystem for Linux.Įach method has unique considerations. PrerequisitesĪn initial step in leveraging the power of RAPIDS for multi-GPU training is the correct installation of RAPIDS libraries. Installation using the latest version of RAPIDS and the correct version of XGBoost.īe sure to follow along with the accompanying Notebooks for each section.The dataset has 180 million rows and 152 columns, totaling 110 GB when loaded into memory.

I use the Otto Group Product Classification Challenge dataset to demonstrate the OOM problem and how to fix it. Training XGBoost on large datasets presents a variety of challenges. This post explores how you can optimize Dask XGBoost on multiple GPUs and manage memory errors. Converting the DataFrame into XGBoost’s DMatrix formatĪddressing these memory issues can be challenging, but very rewarding because the potential benefits of multi-GPU training are enticing.Dask is a flexible open-source Python library for parallel computing and XGBoost provides Dask APIs to train CPU or GPU Dask DataFrames.Ī common hurdle of training Dask XGBoost is handling out of memory (OOM) errors at different stages, including Yet, many users have found it challenging when attempting to leverage this power through Dask XGBoost. Using multiple GPUs should theoretically provide a significant boost in computational power, resulting in faster model training. One commonly used tool, XGBoost, is a robust and efficient gradient-boosting framework that’s been widely adopted due to its speed and performance for large tabular data. As data scientists, we often face the challenging task of training large models on huge datasets.
