When calling `fit` with a reward scaler on a dataset with varied episode lengths, the following error would be thrown in the `fit_with_trajectory_slicer` method: ``` ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. ``` This commit fixes the issue by flattening the rewards before calculating the mean and std.
