ai-models-fuxi_s2s

ai-models-fuxi_s2s is an ai-models plugin to run Fudan's FuXi-S2S.

Installation

To install the package, run:

pip install ai-models-fuxi-s2s

This will install the package and its dependencies, in particular the ONNX runtime. The installation script will attempt to guess which runtime to install. You can force a given runtime by specifying the the ONNXRUNTIME variable, e.g.:

ONNXRUNTIME=onnxruntime-gpu pip install ai-models-fuxi-s2s

Specifying ensemble numbers

There are three ways to control the ensemble members and behaviour of the FuXi-S2S ai-model.

Description	Args	Result
`type=fc`, single member	`--num-ensemble-members 0`	Will create a `grib` file of `type=fc`
N members per process with ID = `range(num-ensemble-members)`	`--num-ensemble-members $N>1`	N ensemble members created all in same process, with id from the range
N members per process with controlled ID	`--num-ensemble-members $N>1` `--member-number 1,2...N`	N ensemble members created all in same process, with id controlled from `member-number`

With these approaches it is possible to create either a single forecast, many ensembles in a single process, or many ensembles over many processes.
