Python-casacore is a set of Python bindings for casacore, a c++ library used in radio astronomy. Python-casacore replaces the old pyrap.

The python-casacore documentation can be found on


Binary wheels

We distribute binary manylinux2010 for Linux, which requires pip > 10.x. To install python-casacore from a binary wheel run:

$ pip install python-casacore

Debian & Ubuntu

python-casacore is now part of Debian and Ubuntu and can be installed using apt:

$ sudo apt-get install python-casacore


If you want a more up to date version of python-casacore and you are running the latest Ubuntu LTS you can enable the KERN suite repository and install the binary package

$ sudo apt-get install software-properties-common
$ sudo add-apt-repository ppa:kernsuite/kern-5
$ sudo apt-get update
$ sudo apt-get install python-casacore

from source

install these requirements:

On ubuntu you can install these with:

$ apt-get install casacore-dev python-numpy \
    python-setuptools libboost-python-dev libcfitsio3-dev wcslib-dev
  • compile and install:

    $ pip install --no-binary python-casacore python-casacore
  • or if you are installing from the source repository:

    $ python ./ install
  • If the compilation fails you might need to help the compiler find the paths to the boost and casacore libraries and headers. You can control this with the CFLAGS environment variable. For example on OS X when using homebrew and clang you need to do something like this:

    CFLAGS="-std=c++11 \
            -I/usr/local/Cellar/boost/1.68.0/include/ \
            -I/usr/local/include/  \
            -L/usr/local/Cellar/boost/1.68.0/lib \
            -L/usr/local/lib/" \
            pip install python-casacore
