Import error

when I just import some model , I get a segmentation fault as below:
from PySide2.QtWidgets import QMainWindow,QMenu,QAction
from PySide2.QtGui import QImage,QPixmap,QCursor
from PySide2.QtCore import QTimer,QSize,QDateTime
import numpy as np
import mxnet as mx
from skimage import transform

Segmentation fault: 11

my pyside2 version “5.12.1”
numpy version ‘1.14.0’
mxnet version ‘1.4.0’
skimage version ‘0.13.1’

or just import like this:
import PySide2
import numpy
import mxnet
from skimage import transform

I get the same error.

How did you install MXNet on your computer? Did you use pip or you build it from source?

pip install mxnet-cu90

Now I remove skimage transform to covered this problem. But that was wired and worrying bug.
