Issue in make OPENFST=/path/to/your/openfst

I am using pytorch 1.5 and using python setup_1_0.py install in the ctc_crf/Makefile.

Can you pls suggest next steps?

This may have something to do with the pytorch version.

Hi, I am getting following error now:

Make sure to have openfst installed and set the path correctly.

Thanks a lot for your prompt response. Will try it out.

Hi I also encountered this issue recently. Here is my solution in Step3: Install CTC-CRF module

make OPENFST=<path to openfst> # note the key point is that this should be an ABSOLUTE PATH instead of relative path

I think it would be better if specify this explicitly in the file installing-cat-tutorial.md, right?
