Change:
something wrong with import torchvision Traceback (most recent call last): File "", line 3, in <moduleimport torchvision File "", line 4, in <moduleimport torchvision.transforms as transforms ImportError: No module named transforms
you have a file called for some reason. delete it or change your pythonpath to ignore it.
Hey, I have the same problem persisting when I import torchvision. I have no other file by the same name. ImportError Traceback (most recent call last) <ipython-input-6-3baf6837d8f1in <module() 8 from import Dataset 9 from import DataLoader ---10 from torchvision import transforms ImportError: No module named torchvision Any idea why this is happening?
Do you have torchvision installed (it is a separate package)?
pip Install torchvision try this
from data import BaseTransform,VOC_CLASSES as labelmap this is not working
pip install torchvision
