Hi @amit007,

Have you tried to update your environment again using the version 0.7 source code ?

I occured the same problem, how can you solved? I have fastai==1.0.11

I apparently solved the cv2 import problem by importing it directly as ‘import cv2’. It seems to work but I won’t know for sure until I find out how to import FilesDataset. I believe that I have fastai v1.0.24, but I am at work so not positive.

Hope that helps,
Vettejeep

I solved the cv2 problem by importing ’ import cv2 ’ in transforms.py.

How you did this?

I have the same error using the kaggle kernel. I installed fastai==0.7.0 via pip and then tried import cv2 but still can’t import conv_learner.
