[Lot of people have this issue] Porotype still does not load after installing the nightly build

Same unsolved issue:

Offical Colab [Same issue and not working]: Google Colab

Same Github Issue[Unsolved] : ASR Inference tutorial not working · Issue #2336 · pytorch/audio · GitHub

You might be missing the import as it works for me:

>>> import torchaudio.prototype
>>> torchaudio.prototype
<module 'torchaudio.prototype' from '/opt/conda/lib/python3.8/site-packages/torchaudio/prototype/__init__.py'>

If it is working on your colab, do you mind sharing it with me?

The import fails with a missing libcudart.so, so I guess you might have updated torchaudio for the wrong CUDA runtime in Colab.
Check the CUDA runtime version via torch.version.cuda and update to the binaries using the same CUDA runtime.

That OSError corresponding to the missing shared object file seems to imply a mismatch in torch and torchaudio versions.

The following works for me in the Colab notebook:

!pip3 uninstall -y torch torchvision torchaudio
!pip3 install --pre torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/nightly/cpu

from torchaudio.prototype.ctc_decoder import download_pretrained_files

Start from a fresh/restarted runtime, and run it at the very top.

Thank you. It works.
