This section describes how to install Python
datatable on various systems.
Python 3.5 or newer is a prerequisite. You can check your python version via
$ python --version
If you don’t have Python 3.5 or later, you may want to download and install the newest version of Python, and then create and activate a virtual environment for that Python. For example:
$ virtualenv --python=python3.6 ~/py36 $ source ~/py36/bin/activate
Install on Mac OS X and Linux¶
Run the following command to install
datatable on Mac OS X and Linux:
$ pip install datatable
Install on Windows¶
Currently datatable does not work on Windows. There is an open issue #1114 to add support for Windows platforms, and there is a certain amount of progress in that direction; however, there are still some unresolved problems.
Build from Source¶
In order to install the latest development version of datatable directly from GitHub, run the following command:
$ pip install git+https://github.com/h2oai/datatable
datatable is written mostly in C++, you will need to have a C++
compiler on your computer. We recommend either Clang 4+, or gcc 5+,
however in theory any compiler that supports C++11 should work.
It is also possible to build datatable with gcc 4.8, which has only partial support of C++11 features. In this case, datatable’s functionality will be limited, and any function using regular expressions will not be supported.
If you want to tweak certain features of
datatable, or even add your
own functionality, you are welcome to do so.
- First, clone
datatablerepository from GitHub:
$ git clone https://github.com/h2oai/datatable
$ make test_install $ make
- Additional commands you may find occasionally interesting:
# Build a debug version of datatable (for example suitable for ``gdb`` debugging) $ make debug # Generate code coverage report $ make coverage # Build a debug version of datatable using an auto-generated makefile. # This does not work on all systems, but when it does it will work # much faster than standard "make debug". $ make fast
If you get the error
ImportError: This package should not be accessible on Python 3, then you may have a
PYTHONPATHenvironment variable that causes conflicts. See this SO question for details.
If you see an error
'Python.h' file not found, then it means you have an incomplete version of Python installed. This is known to sometimes happen on Ubuntu systems. The solution is to run
apt-get install python-devor
apt-get install python3.6-dev.
On OS X, if you are getting an error
fatal error: 'sys/mman.h' file not found, this can be fixed by installing the Xcode Command Line Tools:
$ xcode-select --install
