Lesson 2: Error rate not reducing

In Lesson 2 of the course, in the bears classification problem, the error rate starts from 0.02 when doing fit one cycle, but when I try it, it always starts with 0.65 and I am not able to understand why. The number of images I have is around 150 for each class.

Update : Same date , but if I fall back to older version of the library , then the error rate starts from 0.35 .But the error rate is still increasing

Re running the notebook , it now starts with 0.02 , which is same as shown in video , still not sure what changed
