natcap.invest python package is currently only supported in Python
2.7. Other versions of python may be supported at a later date.
Python 2.7.11 or later is required to be able to use the InVEST Recreation model on Windows.
InVEST itself depends only on python packages, but many of these package dependencies depend on low-level libraries or have complex build processes. In recent history, some of these packages (notably, numpy and scipy) have started to release precompiled binary packages of their own, removing the need to install these packages through a system package manager. Others, however, remain easiest to install through a package manager.
Linux users have it easy, as almost every package required to use
natcap.invest is available in the package repositories. The provided
commands will install only the libararies and binaries that are needed, allowing
pip to install the rest.
Ubuntu & Debian¶
The package versions in the debian:stable repositories often lag far behind the latest releases. It may be necessary to install a later version of a libarary from a different package repository, or else build the library from source.
$ sudo apt-get install python-dev python-setuptools python-gdal python-rtree python-shapely python-matplotlib python-qt4
$ sudo yum install python-devel python-setuptools gdal-python python-rtree python-shapely python-matplotlib PyQt4
Mac OS X¶
The easiest way to install binary packages on Mac OS X is through a package manager such as Homebrew:
$ brew install gdal spatialindex pyqt matplotlib
The GDAL, PyQt and matplotlib packages include their respective python packages.
The others will allow their corresponding python packages to be compiled
against these binaries via
While many packages are available for Windows on the Python Package Index, some may need to be fetched from a different source. Many are available from Christogh Gohlke’s unofficial build page: http://www.lfd.uci.edu/~gohlke/pythonlibs/
PyQt4 installers can also be downloaded from the Riverbank Computing website.
natcap.invest are listed in
gdal>=1.11.2,<2.0 matplotlib natcap.versioner>=0.4.2 pygeoprocessing>=0.4.2 numpy>=1.11.0 rtree>=0.8.2 scipy>=0.16.1 shapely setuptools>=8.0
PyQt4 is required to use the
invest cli, but is not
required for development against
natcap.invest. PyQt4 is not currently
available from the Python Package Index, but other sources and package managers
allow for straightforward installation on Windows,
Mac OS X, and Linux.
Installing from Source¶
Windows users will find best compilation results by using the MSVC compiler, which can be downloaded from the Microsoft website. See the python wiki page on compilation under Windows for more information.
Assuming you have a C/C++ compiler installed and configured for your system, and dependencies installed, the easiest way to install InVEST as a python package is:
$ pip install natcap.invest
If you are working within virtual environments, there is a documented issue
in setuptools that may cause problems when importing packages within the
natcap namespace. The current workaround is to use these extra pip flags:
$ pip install natcap.invest --egg --no-binary :all:
Installing the latest development version¶
Pre-built binaries for Windows¶
Pre-built installers and wheels of development versions of
for 32-bit Windows python installations are available from
http://data.naturalcapitalproject.org/invest-releases/#dev, along with other
distributions of InVEST. Once downloaded, wheels can be installed locally via
> pip install .\natcap.invest-3.3.0.post89+nfc4a8d4de776-cp27-none-win32.whl
Installing from our source tree¶
The latest development version of InVEST can be installed from our Mercurial source tree:
$ pip install hg+https://bitbucket.org/natcap/invest@develop
