WebbIn the past, you had only one tool for solving this specific problem: Python’s OrderedDict.

WebbThis Python class serves as a ray-based solution to instantiate and coordinate multiple data collectors in a distributed cluster. Like TorchRL non-distributed collectors, this collector is an iterable that yields TensorDicts until a target number of collected frames is reached, but handles distributed data collection under the hood.

WebbFor initial conditions, we assume the pendulum is nearly vertical with `theta(0)` = `pi` - 0.1, and is initially at rest, so `omega(0)` = 0. Then the vector of initial conditions is >>> y0 = np.pi - 0.1, 0.0. We will generate a solution at 101 evenly spaced samples in the interval 0 <= `t` <= 10.
