IPython-5.8.0 is broken on python-3.8, due to changes to ast.Module:
In [1]: import pandas
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
/usr/local/lib/python3.8/codeop.py in __call__(self, source, filename, symbol)
134
135 def __call__(self, source, filename, symbol):
--> 136 codeob = compile(source, filename, symbol, self.flags, 1)
137 for feature in _features:
138 if codeob.co_flags & feature.compiler_flag:
TypeError: required field "type_ignores" missing from Module
This issue has been addressed by upstream in newer versions [0].
Updating to a newer version of IPython will take a bit of time because
of the DEPS (more recent versions are required). For the time being
apply a minimal patch.
Run tested on amd64.
