WebThis method creates decorators for instance methods to transform an input tensor `X` to t-batch mode (i.e. with at least 3 dimensions). This assumes the tensor has a q-batch dimension. The decorator also checks the q-batch size if `expected_q` is provided, and the output shape if `assert_output_shape` is `True`.
