Unity barracuda, tensor to implement an onnx model

Question

Tensor inputTensor = new Tensor(1, 30 * 258, 30*258, 1, keypointsSequence.ToArray());

I need to make that barracuda tensor work for an onnx model that receives as input the dimensions (1, 30, 258), I don't know why it doesn't give me and it generates an error.

I am also using barracuda, In addition to this it tells me that the entry is wrong and gives me these problems:
