r"""Collects the scalars broadcasted by `report()` and `report0()` and computes their long-term averages (mean and standard deviation) over us

Convenience class that behaves like a dict but allows access with the attribute syntax.

Samples pitch and yaw from a Gaussian distribution and returns a camera pose. Camera is specified as looking at the origin. If horizontal

Redirect stderr to stdout, optionally print stdout to a file, and optionally force flushing on both stdout and the file.

Same as GaussianCameraPoseSampler, except the camera is specified as looking at 'lookat_position', a 3-vector. Example: For a camera

Same as GaussianCameraPoseSampler, except the pose is sampled from a uniform distribution with range +-[horizontal/vertical]_stddev. Exa
