Hello, I am having an issue following this code snippet:
https://github.com/csukuangfj/kaldifst/blob/d83a76ecba5e0a198231855910f90e4b24b5c7f5/kaldifst/python/tests/test_k2_converter.py#L5

I was trying to import k2_to_openfst but it failed. Here is an google colab notebook to reproduce the issue:

Would you mind taking a look, or suggest how to resolve it? Thanks a lot!

@huangruizhe
Could you try the latest version v0.7? I just fixed it.

csukuangfj commented

By the way, you can use

export KALDIFST_MAKE_ARGS="-j6"
pip install kaldifst

to use 6 tasks to compile kaldifst, which can reduce compilation time.

If you have plenty of CPUs and memory, you can replace -j6 with -j.

Great and many thanks! And thanks for the great suggestion. I will try it now.

It works!! For both the importing issue and the speeding up of compilation time.
Thank you so much!
