Hi. I run the code accordingly as in the picture but an error occur on the line
learn = cnn_learner(data, arch)
(I omitted “metrics” because I was wondering whether it causes the error. But It seems that wasn’t the case)
The last error line was "<urlopen error [Errno -3] Temporary failure in name resolution>"
Any help is appreciated !
PS. I have run this notebook in google colab and the error was not showing. But I switched to kaggle because the downloaded dataset on google colab notebook seemed to be deleted everytime I restart the session.
