Problem when trying to install federated plugin

#1

Hello, it’s been weeks that i’ve been trying to install xgboost’s federated plugin, but i always get cmake errors whenever i try to build the plugin. I am trying to use the plugin in order to execute xgboost in the nvidia simulator in a federated way. I am trying to do this in google colab since i have a mac. Is there a comprehensible guide i can follow?

#2

In particular, whenever i try to build following the instructions reported here: https://github.com/dmlc/xgboost/tree/master/plugin/federated

i get the following error:
"
CMake Error at plugin/federated/CMakeLists.txt:4 (find_package):
Could not find a package configuration file provided by “Protobuf” with any
of the following names:

ProtobufConfig.cmake
protobuf-config.cmake

Add the installation prefix of “Protobuf” to CMAKE_PREFIX_PATH or set
“Protobuf_DIR” to a directory containing one of the above files. If
“Protobuf” provides a separate development package or SDK, be sure it has
been installed.

"

Any help would be appreciated!

The official Python package already includes the federated plugin. Have you tried using the federated learning example after running pip install xgboost?

#4

yes, but when i try to run nvflare’s federated xgboost example given here: https://github.com/NVIDIA/NVFlare/tree/main/examples/advanced/xgboost
i get the following error: “xgboost.core.XGBoostError: XGBoost needs to be built with the federated learning plugin enabled in order to use this module”.
So i tried to build it myself using dmlc github xgboost repository.

Are you using Linux with amd64 CPU on Google Colab?

#6

Also make sure you are using the latest version of XGBoost.

Are you building it on a mac? Probably need to follow the instructions to build gRPC first: https://grpc.io/docs/languages/cpp/quickstart/
