How do I got token_weights from onnx inference?

When I try onnx-community/gte-multilingual-base, I can found there are two outputs
['token_embeddings', 'sentence_embedding']
outputs_meta = self._session.get_outputs()
output =[node.name for node in outputs_meta]
print('Outputs: ', output)
After inference, outputs_onnx has two members, outputs_onnx[1] is the sentence_embedding.
But outputs_onnx[0] are 6 list[float] like below:
token_embeddings out puts: [[[-1.5273438 1.9277344 -0.77685547 ... 0.6074219 0.28857422 -1.5166016 ] [-1.6230469 1.2304688 -0.79003906 ... 0.5473633 0.35253906 -0.6826172 ] [-1.5107422 1.1708984 -0.74609375 ... 0.49047852 0.1928711
-0.5253906 ] [-1.5 1.0712891 -0.79248047 ... 0.3005371 0.0668335 -0.29370117] [-1.4746094 1.171875 -0.8046875 ... 0.6591797 0.20800781
-0.8466797 ] [-1.4042969 1.2041016 -0.6269531 ... 0.29174805 0.3125
-1.0458984 ]]]
Which compare to gte_embeder.py，after
token_weights = torch.relu(model_out.logits).squeeze(-1)
token_weights is 6 floats weight as below:
tensor([[0.9023, 0.8047, 2.7324, 3.8789, 0.9346, 1.5498]], device='cuda:0',
dtype=torch.float16)
Both are encode string 'Where is Munich?'
So how do I covert the 6 List[float] to those 6 real weights?
