Unfamiliar Error when Running learn.fit()

Part 1 (2018)
10

I tried following the suggestions from Cesare:

!pip install Pillow==4.1.1
!pip install fastai==0.7.0
!pip install torchtext==0.2.3
!pip install blosc
But I am still getting the exact same error when I run learn.fit()
AttributeError: ‘list’ object has no attribute 'round
AttributeError: ‘float’ object has no attribute ‘rint’
