Errors of cdo=Cdo(), in Ubuntu 16.04, Anaconda2-5.0.1-Linux-x86_64

Added by Guobao Song almost 7 years ago

Hi all:

I refreshed my system with new Utuntu 16.04, and installed the Anaconda2.

Through the termimal, I put in the cdo and python-cdo, by using the followed commands, referring to https://code.mpimet.mpg.de/projects/cdo/wiki/Anaconda

conda config --add channels conda-forge
conda install cdo
conda install python-cdo

cdo and python-cdo are available

But when I opened Spyder by Anaconda-navigator, and typed:

from cdo import *
cdo=Cdo()

errors appeared as follows:

Traceback (most recent call last):

I get the same error. On my system the cdo installed by conda does not work. it lacks a library:

m300064@breeze3:~$ cdo -V
cdo: error while loading shared libraries: libiconv.so.2: cannot open shared object file: No such file or directory

on my system tweo libs ar missing

  • libiconv: can be installed with conda install libiconv
  • libcom_err: which seem to be related to e2fsprogs, but that has to be installed on the system already - conda does not have any package like this. I guess it is on the building system for conda, but not on my machine. Since a special shared object is needed (libcom_err.so.3) it should be added to conda or used static linking.

I could solve the problem using miniconda3 by calling 

cdo install hdf5
after the two other packages (cdo,python-cdo). But with Anaconda2 it is not solvable for me - maybe with root-access

Found the fix for Anaconda: 

conda install krb5

at least solved the issue for me ;-)

Dear ralf:

Thank you very much for your time-intensive effort to help me address this issue.

In terminal, the issue was resolved by updating all package version by using the follows:

conda update -all

Thanks again :) (/)

Thx for the hint - I put this into the Anaconda docu.
