Problem running code in Ch1

Running the code path = untar_data(URLs.CAMVID_TINY)
dls = SegmentationDataLoaders.from_label_func(
path, bs=8, fnames = get_image_files(path/“images”),
label_func = lambda o: path/‘labels’/f’{o.stem}_P{o.suffix}’,
codes = np.loadtxt(path/‘codes.txt’, dtype=str)
)

learn = unet_learner(dls, resnet34)
learn.fine_tune(8)
from Chapter 1
gives me this error
NameError: name ‘SegmentationDataLoaders’ is not defined

How do I fix it?

Can you please confirm if you have imported all the required packages

Make sure vision module is imported.

from fastai.vision.all import *

Can you try colab?

As pointed out by @msivanes you can do that …
