Installation¶

Installing the code with Anaconda¶

Anaconda is probably the easiest way to install pdspy because the dependency GALARIO is easily conda-installable. pdspy is available on the conda-forge channel and can be installed from the command line with:

conda install pdspy -c conda-forge

Installing the code with pip¶

In a terminal, run:
```
pip install pdspy
```
Install GALARIO. Unfortunately, GALARIO is not pip-installable by default, so you will need to follow the instructions here. Alternatively, a pip-installable version of GALARIO is in the works and can be installed like so:
```
pip install git+https://github.com/psheehan/galario.git@add_unstructured
```

but note that this is a fork of GALARIO and is not yet completely merged.

Installing the code manually¶

If you would like the most cutting-edge version of pdspy, with updates that go beyond the pre-packaged versions, you can download and compile the code yourself following these instructions:

Download the code from this webpage. Git clone is recommended if you would like to be able to pull updates:
```
git clone https://github.com/psheehan/pdspy.git
```
Install the Python dependencies:
- numpy
- scipy
- matplotlib
- emcee
- corner
- hyperion
- h5py
- mpi4py
- galario
- Cython
- astropy < 4.0
- schwimmbad
- dynesty
In a terminal, go to the directory where the code was downloaded, and into the code directory. Run:
```
python setup.py install
```
or
```
pip install -e .
```
or
```
conda build pdspy -c conda-forge
conda install pdspy -c conda-forge --use-local
```
depending on what method you prefer best.

Other dependencies¶

The other codes that are needed to run pdspy are Hyperion and RADMC-3D. If you are a Homebrew user, you can do this with:

brew tap psheehan/science
brew install hyperion
brew install radmc3d
