mppi_torch's Issues
Allow for arbitrary ancillary controllers
Add the possibility of passing an ancillary controller object, which should probably create a tensor of input sequences to be sampled by the mppi controller.

Did the halton-spline mode work
Dear author,
Hello! I have a question for the part of "halton-spline", the code in mppi.py is shown as below.
elif self.mppi_mode == 'halton-spline':
# shift command 1 time step
saved_action = self.mean_action[-1]
self.mean_action = torch.roll(self.mean_action, -1, dims=0)
self.mean_action[-1] = saved_action
cost_total = self._compute_total_cost_batch_halton()
action = torch.clone(self.mean_action)
In this part, the final 'action' is given by the mean of 'saved_action', and it only has a 'shift' operation and no other operations.
Is the method work, could you please explain this part. Thanks for your help.
Best wishes
