Can ROCKET on the GPU be used with TSRegression()? #888

I've followed the tutorial 02_ROCKET_a_new_SOTA_classifier to use ROCKET on GPU but that tutorial is for a classifier like RidgeClassifierCV.

Is there a way to use ROCKET on the GPU with regression? I've try to use TSRegression() both with and without a loss function and I can't get it to work.

X, y, splits = combine_split_data([X_train, X_valid], [y_train, y_valid])

tfms = [None, TSRegression()]
batch_tfms = TSStandardize(by_sample=True)
dls = get_ts_dls(X, y, splits=splits, tfms=tfms, drop_last=False, shuffle_train=False, batch_tfms=batch_tfms, bs=10_000)
model = build_ts_model(ROCKET, dls=dls)
learn = Learner(dls, model, metrics=accuracy, cbs=ShowGraph())

X.shape, y.shape
((2125, 1525, 30), (2125,))

learn.fit_one_cycle(10, 3e-4)

Traceback (most recent call last):

I reinstalled tsai with the latest version 0.3.9 and that resolved the issue
