Is that OK to use Openfst 1.8.1 in Kaldi's latest version? #4884

Open Xiao-persol opened 8 months ago

Xiao-persol commented 8 months ago

I am a beginner and I am trying to install Kaldi. When I finished installing Kaldi, I realised that I also needed to install Openfst. As Openfst version 1.7.2 is bundled in the tools folder of Kaldi, I tried to install it but it failed. Therefore, I installed version 1.8.1 and succeeded. However, I want to know if it is okay to install a different version of Openfst. And if I want to change the openfst which is in Kaldi's tools folder to a newer version, would this affect Kaldi. Could someone please help me on this? Thanks in advance!

Can you explain how it failed? Without details it's hard to know whether it was even OpenFST related. I am actually surprised you were able to install using OpenFST version 1.8.1, because there are incompatibilities in the code. Likely you installed OpenFST in system space, and Kaldi was picking up the 1.7.2 version installed in kaldi/tools/. See this https://github.com/kaldi-asr/kaldi/pull/4716 ... we are not upgrading to 1.8.1 because it's not possible to upgrade Kaldi's code to support that OpenFST version without breaking existing builds, and there was no compelling version to upgrade.

@danpovey Thanks for the reply, now I know there are incompatibilities between 1.8.1 and 1.7.2. And as you said, I had OpenFST installed in system space, not actually installed in Kaldi. But the reason I was trying to install openfst1.8.1 was that I could not successfully #make openfst-1.7.2 by using python3.9.

I think there might be something wrong with my python version. Anyway, thanks again!

I wasn't aware that the OpenFST build script had any dependencies on python. Until I see concrete output from the screen I cannot really start to help.
