GPyTorch Regression Tutorial gives "you must train on training inputs!"

[Atulsingh92]

Hello,

Tried the basic "GPyTorch Regression Tutorial" for v1.6.0, given here,
get an error at the line

 f_preds = model(test_x)

  File ~\Anaconda3\envs\gpytorch_env\lib\site-packages\gpytorch\models\exact_gp.py:256 in __call__
    raise RuntimeError("You must train on the training inputs!")

RuntimeError: You must train on the training inputs!

Could someone help?

Before calling f_preds = model(test_x), call model.eval().
