support for openFst new versions

[mohamad-hasan-sohan-ajini]

Hi

I try to install OpenFst 1.6 and then install pyfst. but I get error while installing pyfst. However by reverting OpenFst to version 1.3, the problem was solved, but is there any plan to support most recently releases of OpenFst (1.6 at this time)?

regards

Indeed, Kaldi 5.1.65 seems to require openfst > 1.6.0, downgrading to 1.3.x is not an option anymore.

My openfst is built with --enable-far, but pyfst isn't able to build even with "-std=c++11"

Any other ideas?

This fork https://github.com/UFAL-DSG/pyfst/ gets us a step further, but I think we're still incompatible with openfst 1.6.

The FstDrawer function signatures are incompatible across OpenFST 1.6 and the current version of pyfst. I had to fix the two files fst/libfst.pxd.tpl and fst/_fst.pyx.tpl to get it to work with 1.6.2.

Y'all realize there's an official OpenFst Python wrapper with significantly more functionality than pyfst, that it is continuously maintained, it's compatible with recent versions of OpenFst, right?

python.openfst.org

(Please forgive cross-promotion here.)

This branch(https://github.com/placebokkk/pyfst) supports 1.6 by fix FstDrawer interface.

No we don't, https://www.openfst.org/ is down most of the time and not easy to navigate, so thanks for the hint ! But in the end I could not make it work, nor any other existing wrapper.
