Something is amiss here as your `conda list` does not show GDAL as installed?!?! I was just having issues like yours late last week with GDAL and a `conda update --all` helped resolve it.<br>

Greetings,<br>
<br>
This is likely a conflict between a package provided by `conda-forge` and one that is provided by the `defaults` channel.<br>
<br>

<br>
I am finding the currently best success by removing the `defaults` channel completely and just using a pure conda-forge environment. When you then run `conda list`, you should not see any `defaults` channel packages listed as installed.<br>

Subject: [pyngl-talk] Unable to import Nio in a Linux system<br>
<br>
Dear all,<br>
I’m a user changing from NCL to pynio.<br>
Recently I have install the pynio using the recommended conda way (conda create -n ncl_to_python -c conda-forge xarray netcdf4 scipy pyngl pynio ncl).<br>
When I activate the ncl_to_python environment, I cannot import Nio correctly, although the Ngl is running well. The error message is as following:<br>
import Nio<br>
Traceback (most recent call last):<br>
File "<stdin>", line 1, in <module><br>
File "/data2/anaconda3/envs/ncl_to_python/lib/python3.6/site-packages/PyNIO/Nio.py", line 83, in <module><br>
from _nio import *<br>
ImportError: /data2/anaconda3/envs/ncl_to_python/lib/python3.6/site-packages/PyNIO/../../../libgdal.so.20: undefined symbol: _ZN6libdap3DDSC1EPNS_15BaseTypeFactoryERKSs<br>
<br>
Attached is my system information provided by “uname -a”:<br>
Linux R910 2.6.32-431.el6.x86_64 #1 SMP Sun Nov 10 22:19:54 EST 2013 x86_64 x86_64 x86_64 GNU/Linux.<br>
<br>
Is it a bug in the PyNIO 1.5.4, or any other problems in my Linux system?<br>
Many thanks for your help.<br>
Best wishes.<br>
<br>
B. Liu<br>
<br>
