PyCaret 2.1 is now available. Click here to see release notes. Documentation on the website is only updated for major releases. To see the latest documentation, Click Here

Installing PyCaret is the first step towards building your first machine learning model in PyCaret. Installation is easy and takes only a few minutes. All dependencies are also installed with PyCaret. Click here to see the complete list of dependencies.

Make sure compilers (gcc, g, build-essential) and Python development tools (python-dev, python3-dev) are installed. In Red Hat systems, install the packages gcc64 and gcc64-c. If you are using a VM, be aware that you will need at least 4GB of memory to install fbprophet, and at least 2GB of memory to use fbprophet. Initially, GCC handled only the C programming language, but with the development of additional front ends, GCC expanded to compile C, Objective-C, Objective-C, Go, Fortran, Ada, Java and others. GCC also offers support for a wide variety of processor architectures and, as. This post will guide you how to install GNU Gcc compiler on Mac OS X system. How do I install command line tool for xcode package to install Gcc compiler on Mac OS system. How to install gcc command line tool in Mac OS Sierra. The GNU Compiler Collection or GCC for short, comprises front ends for C, Objective-C, C, Java, Fortran, Go and Ada, along with libraries for the mentioned languages. GCC us the main component of the GNU toolchain, it is distributed under the GNU General Public License and plays a central role in the continuous growth of free software.

In the above cmake command, we use the flag GRPYTHONDIR to tell GNU Radio where to install its Python scripts and related SWIG libraries. The path noted in that command will work for the MacPorts installed python2.7 command.

In order to avoid potential conflicts with other packages it is strongly recommended to use a virtual environment, e.g. python3 virtualenv (see python3 virtualenv documentation) or conda environments. Using an isolated environment makes it possible to install a specific version of pycaret and its dependencies independently of any previously installed Python packages. See an example below of how to create a conda environment and install PyCaret.

The following libraries have been removed from hard dependency in PyCaret 2.0. Hence they must be installed separately when specific functionalities are being used. See the code below on how to install these dependencies.

PyCaret is a fast-evolving machine learning library. Often, you want to have access to the latest features but want to avoid compiling PyCaret from source or waiting for the next release. Fortunately, you can now install pycaret-nightly using pip.

We highly recommend to install pycaret-nightly in a virtual environment to avoid conflicts.

You can use PyCaret in your choice of Integrated Development Environment (IDE) but since it uses html and several other interactive widgets, it is optimized for use within notebook environment, be it Jupyter Notebook, Jupyter Lab, Azure Notebooks or Google Colab.

A Docker container runs in a virtual environment and is the easiest way deploy applications using PyCaret. Dockerfile from base image python:3.7 and python:3.7-slim is tested for PyCaret 2.0.

You can also download the source file from the link below and use the pip installer to install the package from a downloaded file. To install the package using the source file, download the file and use the command line or notebook environment to run the below cell of code.

PyCaret uses interactive plotting ability. In order to render interactive plots in Google Colab, run the below line of code in your colab notebook.

MAC users will have to install LightGBM separately using Homebrew, or can be built using CMake and Apple Clang or gcc. See the instructions below:

  1. Install CMake (3.16 or higher)
    >> brew install cmake
  2. Install OpenMP
  3. >> brew install libomp
  4. Run the following command in terminal:

Mac Gcc Install

The following is addressed to an audience who is just getting started withPython and would benefit from additional guidance on how to install PyStan.

Installing PyStan requires installing:

  • Python
  • C++ -compiler
  • Python dependencies
  • PyStan

It is highly recommended to know what bash is and the basics ofnavigating the terminal. You can review or learn it from the SoftwareCarpentry (bash lesson here).

Lessons 1 - 3 are probably the most important.

Installing Python¶

The easiest way to install Python is to use the Anaconda distributionof python. It can be downloaded here.

This is because PyStan (and many python tools) require packages (akamodules) that have C dependencies. These types of dependencies areunable to be installed (at least easily) using pip, which is acommon way to install python packages. Anaconda ships with it’s ownpackage manager (that also plays nicely with pip) called conda,and comes with many of the data analytics packages and dependenciespre-installed.

Don’t worry about Anaconda ruining your current Python installation, itcan be easily uninstalled (described below).

Anaconda is not a requirement¶

Anaconda is not an absolute requirement to get pystan to work. Aslong as you can get the necessary python dependencies installed, pystanwill work. If you want to install Anaconda, follow the Windows, Macs,and Linux instructions below.

Linux¶

After downloading the installer execute the associated shell script. Forexample, if the file downloaded were named Anaconda3-4.1.1-Linux-x86_64.shyou would enter bashAnaconda3-4.1.1-Linux-x86_64.sh in the directory whereyou downloaded the file.

Macs¶

Mac Install Gcc Without Xcode

After downloading the installer, double click the .pkg file and followthe instructions on the screen. Use all of the defaults forinstallation.

Windows¶

PyStan on Windows is partially supported. See PyStan on Windows.

Without

The Anaconda installer should be able to be double-clicked andinstalled. Use all of the defaults for installation except make sure tocheck Make Anaconda the default Python.

Uninstalling Anaconda¶

The default location for anaconda can be found in your home directory.Typically this means it in in the ~/anaconda or ~/anaconda3directory when you open a terminal.

Python dependencies¶

If you used the Anaconda installer, numpy and cython should already beinstalled, so additional dependencies should not be needed. However,should you need to install additional dependencies, we can use condato install them as such:

  • open a terminal
  • type condainstallnumpy to install numpy or replace numpywith the package you need to install
  • common additional packages include arviz, matplotlib, pandas,scipy

Setting up C++ compiler¶

PyStan 2.19+ needs a C++14 compatible compiler. For GCC 4.9.3+ andGCC 5+ versions are up-to-date. To update your compiler, follow generalinstructions given for each platform.

  • Linux: Install compiler with apt/yum
  • Macs: Install latest XCode, or use brew or macports
  • Windows: Follow instructions in PyStan on Windows.

To use gcc/clang compiler from the conda follow instructions inhttps://docs.conda.io/projects/conda-build/en/latest/resources/compiler-tools.htmland set-up your CC and CXX environmental variables as given below. Instructions belowassume default Anaconda environment. For conda-forge follow installationinstructions in anaconda.org.

  • open a terminal
  • Linux: condainstallgcc_linux-64gxx_linux-64-canaconda
  • Macs: condainstallclang_osx-64clangxx_osx-64-canaconda

To check your compiler version

  • Open a terminal
  • Linux: type gcc--version
  • OSX: type clang--version

To use specific C++ compiler (Linux: gcc_linux-64, gxx_linux-64, OSX: clang_osx-64, clangxx_osx-64), either update your CC and CXX environmentalvariables or set-up your path to include folder containing compilers(e.g.``which gcc_linux-64``)

Mac
  • type exportCC=gcc_linux-64 and exportCXX=g++_linux-64
  • type exportPATH=/path/to/Anaconda/bin:$PATH

Conda will create a new name for the compiler. You’ll need to search in the <path to conda>/bin folder to find the name. which python will show this location. For example:

  • Open a terminal
  • OSX: type ls<pathtopythonenv>/bin/|grepclang

You should see two compilers like x86_64-apple-darwin13.4.0-clang and x86_64-apple-darwin13.4.0-clang++.

  • type exportCC=x86_64-apple-darwin13.4.0-clang and exportCXX=x86_64-apple-darwin13.4.0-clang++

Installing PyStan¶

Gcc

Since we have the numpy and cython dependencies we need, we caninstall the latest version of PyStan using pip. To do so:

  • open a terminal
  • type pipinstallpystan
