Two errors with the Rossman lesson (Lesson 3)


(Richard Reis) #1

I get two problems when doing Lesson 3 (Lesson 4 on the lectures).

One is a warning
/home/paperspace/anaconda3/envs/fastai/lib/python3.6/importlib/_bootstrap.py:219: RuntimeWarning: numpy.dtype size changed, may indicate binary incompatibility. Expected 96, got 88
return f(*args, **kwds)
/home/paperspace/anaconda3/envs/fastai/lib/python3.6/site-packages/sklearn/ensemble/weight_boosting.py:29: DeprecationWarning: numpy.core.umath_tests is an internal NumPy module and should not be imported. It will be removed in a future NumPy release.
from numpy.core.umath_tests import inner1d

The other is an error when I try to run for t in tables: display(DataFrameSummary(t).summary())

AttributeError: module 'pandas.core.common' has no attribute 'is_numeric_dtype'

I looked for a solution to both on the forums but couldn’t find it (the closest I got was this link, but none of the solutions worked)

Please help!

Those warnings are not things to be worried about. The error on the other hand has a solution on Stackoverflow: https://stackoverflow.com/a/50828177/6304086
