A radio interferometric modeling tool developed for the Event Horizon Telescope (EHT). The framework employed here utilizes PyMC3 for sampling and the eht-imaging library for VLBI data manipulation.

NOTE: Currently still in testing mode, so no guarantees that code will work at all yet.

To install the most recent version, clone the repository, move into the main directory, and install using pip:

git clone https://github.com/dpesce/eht-dmc.git
cd eht-dmc

sudo apt-get -y install libnfft3-dev  # for pynfft
#sudo apt-get -y install libopenblas-base libopenblas-dev  # need some blas for numpy

pip install cython  # might be needed by pynfft, must be installed before requirements.txt
pip install -r requirements.txt
pip install .

Import the eht-dmc library using the dm alias:

import eht_dmc as dm

For yum-based installs, the EPEL package nfft-devel does not contain the threaded library that pynfft wants to use.

For pyenv-installed pythons, the Theano package requires that python be installed with shared libraries, which is not the pyenv default. Reinstall python like this:

PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install --force 3.X.Y
