I have encountered a problem when import pynio, the error messeage was following:

zpf at zhangpf:~$ source activate pyn_env
(pyn_env) zpf at zhangpf:~$ python
Python 3.6.7 | packaged by conda-forge | (default, Nov 21 2018, 03:09:43)
[GCC 7.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import Nio
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/zpf/miniconda2/envs/pyn_env/lib/python3.6/site-packages/PyNIO/Nio.py", line 83, in <module>
    from _nio import *
ImportError: /home/zpf/miniconda2/envs/pyn_env/lib/python3.6/site-packages/PyNIO/../../../libgdal.so.20: undefined symbol: _ZN6libdap3DDSC1EPNS_15BaseTypeFactoryERKSs
>>> import Ngl

How to solve this problem?
Thank you everyone!
