Error in accompanying Colab: "InternalError: libdevice not found at ./libdevice.10.bc [Op:__inference_tf_forward_55230]"

[Evan R. Murphy]

In an accompanying Colab (different Colab than for #29), under Setting up training state at this step:

predictions, labels = infer_librispeech(dataset, num_batches=2618)

Running all the code in the colab up to this point produces an error here:

---------------------------------------------------------------------------

Hi,
it was happening because colab was unable to re-install tensorflow properly because of some reason. I have removed tensorflow from the requirements.txt as the fix. So, you should be able to run the notebooks now!!

Feel free to open the issue again if you encounter any other problem.
