[ahmed-sevimli]

Describe the bug

I can't run inference on my Python 3.10.12 setup, i get the following syntax error:

  File "C:\NeMo\examples\asr\asr_cache_aware_streaming\speech_to_text_cache_aware_streaming_infer.py", line 117, in <module>
    from nemo.collections.asr.parts.utils.streaming_utils import CacheAwareStreamingAudioBuffer
  File "C:\Users\user\AppData\Local\miniconda3\envs\nemo\lib\site-packages\nemo\collections\asr\parts\utils\streaming_utils.py", line 2467
    shifted_indices = shifted_indices[..., *[None for _ in range(len(self.dim_shape))]]
                                           ^
SyntaxError: invalid syntax

Steps/Code to reproduce bug

I also encountered this issue when reproducing the official streaming recognition. I'm not sure if it's because Python 3.10 isn't supported.
