Actually it was just me being stupid—just re-define all the functions that are assumed by your model.

Yes. We actually go over that once we hit lesson 5 in the study group :)

I'm having the first issue you stated. Can you tell me how you fixed it?

from fastai2.

When you bring your learner back in make sure to re-define any functions your model wants to use along with it

from fastai2.

I did not define any functions, I believe. For instance, I defined these for my model:

dls = ImageDataLoaders.from_folder(path_output, train='train', valid_pct=0.3, bs=8)

learn = cnn_learner(dls, resnet34, metrics=error_rate)
learn.fine_tune(4)

learn.unfreeze()
learn.fit_one_cycle(n_epoch = 10, lr_max = 5e-3)
learn.save('model_34')

Then calling the code below gives the error:

tst_files = get_image_files(path_output/'test')
learn = load_learner(path_output/'models/model_34_unfrozen.pth', cpu=False)
tst_dl = learn.dls.test_dl(tst_files)
