Description
I've been trying to run this notebook in colab: https://github.com/segments-ai/fast-labeling-workflow/blob/master/demo.ipynb
First of all, the notebook has a few mistakes that should be corrected. For example, in this line:
dataset = SegmentsDataset(release, labelset='ground-truth', filter_by='labeled'),
filter_by='labeled' should be removed; otherwise the resulting dataset will be empty. Obviously, the data should not be filtered by 'labeled', before it's labeled.
I fixed this myself, but when I run the cell that has this code snippet:
from utils import train_model
model = train_model(dataset)
I get the error message below. How could I resolve this?
Exporting dataset. This may take a while...
