This is the converted model from Unbabel/wmt22-cometkiwi-da 1) Just kept the weights/bias keys() 2) Renamed the keys to match the original Facebook/XLM-roberta-large 3) kept the layer_wise_attention / estimator layers Because of a hack in HF's code I had to rename the "layerwise_attention.gamma" key to "layerwise_attention.gam" I changed the config.json key "layer_transformation" from sparsemax to softmax because there is a bug in COMET since the flag is not passed, the actual function used is the default which is softmax.
