1. Subtract eps from the node on the left or add eps to the node on the right at the transition (although it is a transition in principle, it needs to be done from the perspective of implementation, and it will have little impact), for example:

[0 2 * pi/3-EPS 2 * pi/3 pi-EPS pi 5 * pi/3-EPS 5 * pi/3 2 * pi]

2. Secondly, the lookup table module is used for unary interpolation, and the n-D lookup table module is not needed. The latter adds unnecessary complexity, and it will still give an error when setting the same parameters as the unary lookup table module. The reason has not been found out yet.

3. Finally, it is more convenient to save the data in the lookup table as variables, and then use variables in the module parameters (especially when the node parameters need to be used many times).
