Error when I install opencv_contrib_python : libhdf5_serial.so.100: cannot open shared object file

[cooldeaaap1]

I am sorry that :
I have usepip install opencv_contrib_python-3.2.0.7-cp35-cp35m-linux_armv7l.whl and It seems OK, but when I
python import cv2

It told me that:Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/pi/.pyenv/versions/3.5.2/lib/python3.5/site-packages/cv2/__init__.py", line 7, in <module> from . import cv2 ImportError: libhdf5_serial.so.100: cannot open shared object file: No such file or directory

evensudo apt-get update sudo apt-get install libhdf5-dev sudo apt-get update sudo apt-get install libhdf5-serial-dev

It didnot work ...
How can I makr it work ?
