Installation

Install the code is as easy as

pip install comet-emu

Then you can follow the Jupyter Notebook for a small example in how to make predictions, compare with data and estimate the \(\chi^2\) of you model.

Developer version

If you want to modify the code and play around with it, we provide a developer version so that you can make it and test it. Also, could be possible that you have your own theoretical predictions and you wish to train the emulator with your own computations. You can install the developer version as follow.

git clone git@gitlab.com:aegge/comet-emu.git
cd comet-emu
pip install -e .

Then you can follow the Jupyter Notebook to learn how to train the COMET and make predictions.

Warning

the comet emulator only works in a Python 3 environment; the data file at its core cannot be unpickled by Python 2.x; in case your pip command doesn’t link to a Python 3 pip executable, please modify the line above accordingly (e.g. with pip3 instead of pip)

Note

The comet emulator depends on the following external packages:

• numpy

• matplotlib

• scipy

• astropy

• GPy

The installation process will automatically try to install them if they are not already present.
