Pandas output is broken after fastai import #1531
Description
Describe the bug
After importing fastai.text, pandas output (like .head()) raises an exception:
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)

The same problem exists with python 3.6 (except with python 3.6 there seems to be a broken dataclasses dependency as well).
To Reproduce
Import pandas, read a dataframe, show head. Then import * from fastai.text. Show head again.
# coding: utf-8
# In[1]:
import pandas as pd
# In[3]:
df = pd.DataFrame(pd.np.zeros((2, 2)))
# In[4]:
df # works fine
# In[5]:
from fastai.text import *
# In[6]:
df # doesn't work nowExpected behavior
Output is the same.
