I am trying to submit to the (closed) plant pathology 2021 competition. I trained a model on colab, using fastai, exported it using learn.export then uploaded it to kaggle, ran it, but am getting this error.
code used to get to this error:
learner = load_learner(m, cpu=False).to_fp32()
test_dl = learner.dls.test_dl(sample)
I’ve initialized the functions used in colab to train like get_x and get_y
I’ve ran this with and without GPU, I’ve run this with and without the fp_32 flag.
The only thing i can see wrong is that the version of pytorch and fastai used to make the model are newer than the ones running on kaggle for offline-only notebooks.
I’d appreciate any help to figure this out.
Next i’m gonna try do the training on kaggle and see if that matters.
Thank you
