Package Installation¶
To install cosmos20_colors into your environment from the source code:
$ cd /path/to/root/cosmos20_colors
$ python setup.py install
Environment configuration¶
The following step is not required, but we recommend you create an environment variable COSMOS20_DRN with the directory where the dataset is stored on your disk. To do this, add the following line to your .bash_profile (for bash users) or .zshrc (for zshell users):
export COSMOS20_DRN="/path/to/drn/containing/cosmos20/data"
Loading the data¶
Once you have added installed the package and created the COSMOS20_DRN environment variable, launch a new terminal so that the variable is activated, and launch a python interpreter. To load the dataset into memory:
>>> from cosmos20_colors import load_cosmos20
>>> galaxies = load_cosmos20()
