- Xgboost.core.XGBoostError: XGBoost Library (libxgboost.dylib) could not be loaded. Likely causes:. OpenMP runtime is not installed (vcomp140.dll or libgomp-1.dll for Windows, libgomp.so for UNIX-like OSes). You are running 32-bit Python on a 64-bit OS As stated in this other question here I am running 64-bit Python since this.
- How to install xgboost in python on macos? Install XGBoost on Mac OS Sierra for Python Programming. Step1: First, build the shared library from the C codes (libxgboost.so). Step2: Then install the Python language packages. Required Software. Step1: Build the Shared Library. XGBoost supports multi-threading.
- For a newbie learning python and Machine Learning on Mac, I would strongly recommand to install Anaconda first (install doc).Anaconda is a freemium open source distribution of the Python and R programming languages for large-scale data processing, predictive analytics, and scientific computing, that aims to simplify package management and deployment.
Mac OS X comes with Python 2.7 out of the box.
You do not need to install or configure anything else to use Python 2. Theseinstructions document the installation of Python 3.
The version of Python that ships with OS X is great for learning, but it’s notgood for development. The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.
If you are using a Mac and want to follow these instructions, it is recommended to install Python from Homebrew. If you are on Linux, use your package manager to install Python 3.x. On Mac, use Homebrew to install Python 3.x. If these instructions do not make sense to you, scroll up and use the instructions for Anaconda.
Doing it Right¶
Let’s install a real version of Python.
Before installing Python, you’ll need to install GCC. GCC can be obtainedby downloading Xcode, the smallerCommand Line Tools (must have anApple account) or the even smaller OSX-GCC-Installerpackage.
If you already have Xcode installed, do not install OSX-GCC-Installer.In combination, the software can cause issues that are difficult todiagnose.
If you perform a fresh install of Xcode, you will also need to add thecommandline tools by running
xcode-select--install on the terminal.
While OS X comes with a large number of Unix utilities, those familiar withLinux systems will notice one key component missing: a package manager.Homebrew fills this void.
To install Homebrew, open
Terminal oryour favorite OS X terminal emulator and run
The script will explain what changes it will make and prompt you before theinstallation begins.Once you’ve installed Homebrew, insert the Homebrew directory at the topof your
PATH environment variable. You can do this by adding the followingline at the bottom of your
If you have OS X 10.12 (Sierra) or older use this line instead
Now, we can install Python 3:
This will take a minute or two.
pip pointing to the Homebrew’d Python 3 for you.
Working with Python 3¶
At this point, you have the system Python 2.7 available, potentially theHomebrew version of Python 2 installed, and the Homebrewversion of Python 3 as well.
will launch the Homebrew-installed Python 3 interpreter.
will launch the Homebrew-installed Python 2 interpreter (if any).
will launch the Homebrew-installed Python 3 interpreter.
If the Homebrew version of Python 2 is installed then
pip2 will point to Python 2.If the Homebrew version of Python 3 is installed then
pip will point to Python 3.
The rest of the guide will assume that
python references Python 3.
Pipenv & Virtual Environments¶
The next step is to install Pipenv, so you can install dependencies and manage virtual environments.
A Virtual Environment is a tool to keep the dependencies required by different projectsin separate places, by creating virtual Python environments for them. It solves the“Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keepsyour global site-packages directory clean and manageable.
For example, you can work on a project which requires Django 1.10 while alsomaintaining a project which requires Django 1.8.
So, onward! To the Pipenv & Virtual Environments docs!

TPOT is built on top of several existing Python libraries, including:
Most of the necessary Python packages can be installed via the Anaconda Python distribution, which we strongly recommend that you use. Support for Python 3.4 and below has been officially dropped since version 0.11.0.
You can install TPOT using
NumPy, SciPy, scikit-learn, pandas, joblib, and PyTorch can be installed in Anaconda via the command:
DEAP, update_checker, tqdm, stopit and xgboost can be installed with
pip via the command:
Windows users: pip installation may not work on some Windows environments, and it may cause unexpected errors. If you have issues installing XGBoost, check the XGBoost installation documentation.
If you plan to use Dask for parallel training, make sure to install dask[delay] and dask[dataframe] and dask_ml. It is noted that dask-ml>=1.7 requires distributed>=2.4.0 and scikit-learn>=0.23.0.
If you plan to use the TPOT-MDR configuration, make sure to install scikit-mdr and scikit-rebate:
To enable support for PyTorch-based neural networks (TPOT-NN), you will need to install PyTorch. TPOT-NN will work with either CPU or GPU PyTorch, but we strongly recommend using a GPU version, if possible, as CPU PyTorch models tend to train very slowly.
We recommend following PyTorch's installation instructions customized for your operating system and Python distribution.
Finally to install TPOT itself, run the following command:
To install tpot and its core dependencies you can use:
To install additional dependencies you can use:
As mentioned above, we recommend following PyTorch's installation instructions for installing it to enable support for PyTorch-based neural networks (TPOT-NN).
Installation for using TPOT-cuML configuration
With 'TPOT cuML' configuration (see built-in configurations), TPOT will search over a restricted configuration using the GPU-accelerated estimators in RAPIDS cuML and DMLC XGBoost. This configuration requires an NVIDIA Pascal architecture or better GPU with compute capability 6.0+, and that the library cuML is installed. With this configuration, all model training and predicting will be GPU-accelerated. This configuration is particularly useful for medium-sized and larger datasets on which CPU-based estimators are a common bottleneck, and works for both the
