Hi,
I am getting this error when training a zipformer model

AttributeError: module 'k2' has no attribute 'swoosh_r'

here is my installation of icefall
https://medium.com/@nadirapovey/k2fsa-icefall-instalation-1085fae845d2
in short I did:

(venv) np@np-INTEL:~/anna$ pip install k2==1.21.dev20221008+cuda11.3.torch1.12.1 -f https://k2-fsa.org/nightly/

In your case, please replace

pip install k2==1.21.dev20221008+cuda11.3.torch1.12.1 -f https://k2-fsa.org/nightly/

with

pip install k2==1.24.3.dev20230725+cuda11.3.torch1.12.1 -f https://k2-fsa.github.io/k2/cuda.html
