when I import kaldi_io, I encountered the problem. Could you help me solve it, thank you very much.

Check that you compiled a shared library for kaldi. Try to add it to your LD_LIBRARY_PATH.

I add the kaldi_io_internal.so to LD_LIBRARY_PATH, but the issue is still.

I can suggest to rebuild kaldi, maybe issue is there. Check if there were errors during the setup of kaldi-python (run it in verbose mode).

I encountered the same problem. I rebuilt the kaldi with configure --share. And I also add the kaldi_io_internal.so to python3.5/site-packages/.
