scaler.inverse_transform error

[MrDubliu]

When executing these lines:
actuals = scaler.inverse_transform(test_y)
or
preds_moving = scaler.inverse_transform(preds_moving)

I am getting this same error:
ValueError: Expected 2D array, got 1D array instead

You can remove the line in preds_moving and have actuals=test_y
The transform sets the data to be between -1 and 1. This is only useful when you are working with data that it outside of -1 to 1. Since this is a sin curve the data doesn't actually change.
