⚠️ IMPORTANT NOTE: eht-dmc is no longer supported software. Interested users should instead see Comrade.jl.

eht-dmc

eht-dmc is 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.

Installation instructions

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 .

Recommendations

Import the eht-dmc library using the dm alias:

import eht_dmc as dm

Additional installation clues

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
