cannot use pykaldi from conda: `GLIBC_2.23' not found #1

Dear pykaldi developers,

I tried to use pykaldi from conda (just having a conda install -c pykaldi pykaldi in a fresh python-3.7 environment, but when trying the example notebook I get this error:

In [1]: from kaldi.util.table import MatrixWriter
ImportError: /lib64/libm.so.6: version `GLIBC_2.23' not found (required by /home/mbernard/.conda/envs/pykaldi/lib/python3.7/site-packages/kaldi/fstext/../lib/libfstscript.so.8)

My system is a centos 7 with glibc 2.17. Note that, when compiled from sources, all is working as expected.

So here is my question: is it possible to change the conda image so that it use a glibc from conda instead of the system one?

Thanks!

Thank you for your comment. We started working on improving the coverage of the conda package. Specifically by building the conda package for centos. However this might take a while as it is not a simple task and we (me and @dogancan) are not that familiar with centos. Any tips on how to build from source in centos?

With regard to your question: it sounds possible to either modify the library paths to prioritize conda glibc or re-write the rpaths to use the conda glibc (e.g., by using patchelf). But that may induce unexpected behavior down the line.

Ok thank you, I never did any conda package so I can't help you on that hand. But for the compilation on centos, just following https://github.com/pykaldi/pykaldi#from-source is fine.

The install of dependencies change a little bit, but nothing complicated: yum install autoconf automake cmake3 curl graphviz atlas-devel libtool make subversion unzip wget zlib-devel
Then you must make a shortcut from cmake3 to cmake: ln -s /bin/cmake3 /usr/bin/cmake
Finally you need a version of git more recent that the one in the official repos (supporting the -c option). So I installed alternatives repos from https://ius.io. Then yum install git2u.

Hey @mmmaat, I just updated the packages in anaconda. These are built in CentOS7.

Could you try them out and see if this issue persists?

You may have to create a new env or update your current installation, make sure you have the ones that end in _6 (e.g.,pykaldi: 0.0.9-py36h7c1a757_6 pykaldi )

Thank you, all is working now (I used the latest version suffixed _7).

That is great! Thanks for letting me know
