How to solve PyObject numpy.ufunc size changed, may indicate binary incompatibility?

Hi there, been using my env some time and probably installed a lot of things… when I do from fastai2.vision.all import * I get the following warning:

/home/tyoc213/miniconda3/envs/fastai2/lib/python3.7/importlib/_bootstrap.py:219: RuntimeWarning: numpy.ufunc size changed, may indicate binary incompatibility. Expected 192 from C header, got 216 from PyObject return f(*args, **kwds)

Thought apparently I havent hit a real problem guess it will cause some error in some place.

So, I was thinking on deleting all pyc or something like that?
