Installation

Install the package via pip using the following command:

• python3 -m pip install GPyS

Example Use

After installing the package you can load it via:

For GPS Preprocessor:

• from GPyS_preprocessor import Preprocessor
• Note that only Preprocessor.setup(X) takes in argument X and this must be called first before any other functions
• The remaining functions merely returns preprocessing quantities of interests

For GPS Prediction:

• from GPyS_prediction import Prediction
• All the functions can be independently called here.
• Also, user can directly call Prediction.GPS_Prediction() to immediately obtain prediction results
