fairchem>=2.0

We plan to bring back the following models compatible with Fairchem V2 soon:

• Gemnet-OC

• EquiformerV2

• eSEN

Using Fairchem V1¶

If you need to use models from fairchem version 1, you can still do so by installing version 1:

pip install fairchem-core==1.10

And using the OCPCalculator:

from fairchem.core import OCPCalculator

calc = OCPCalculator(
    model_name="EquiformerV2-31M-S2EF-OC20-All+MD",
    local_cache="pretrained_models",
    cpu=False,
)
