"Segmentation fault" if numpy>=2

[al-zatv-mybuddy-ai]

I have "Segmentation fault" error during creating of DecodableCtc in lines:

            log_probs = log_probs.squeeze(0).cpu().numpy()
            decodable = DecodableCtc(log_probs, offset=n)

of icefall/egs/librispeech/ASR/zipformer/onnx_pretrained_ctc_HLG_streaming.py

Fix: python -m pip uninstall numpy; python -m pip install 'numpy<2'
Uninstalled numpy have version 2.1.2, newly installed numpy was 1.26.4.

Expected behaviour: to have requirement to numpy version in kaldi_decoder metadata, or to show meaningful error during initialization of kaldi_decoder or DecodableCtc , or to make it work with both numpy versions.

Please use

pip install "numpy<2"
