Yes, the training curves look normal.

I encountered the same problem, did you solve it?

But I only find one when I run `pip uninstall k2` ``` Found existing installation: k2 1.24.3.dev20230707+cuda11.7.torch1.13.0 Uninstalling k2-1.24.3.dev20230707+cuda11.7.torch1.13.0: Would remove: /opt/conda/envs/k2v6/lib/python3.8/site-packages/k2-1.24.3.dev20230707+cuda11.7.torch1.13.0-py3.8-linux-x86_64.egg Proceed (Y/n)? ```

Yes, I find two files. After delete old one, it runs successfully! Thank you very much!

I have encountered the same problem on libriheavy dataset, and solve it by adjust ``` cut["start"] = round(cut["start"], 2) cut["features"]["start"] = round(cut["features"]["start"], 2) ```
