["Hi ! I wasn't able to reproduce the error, are you still experiencing this ? I tried calling `cast_column` on a string column containing paths.\r\n\r\nIf you manage to share a reproducible code example that would be perfect"
 'Hi,\r\n\r\nI think my team mate got this solved. Clolsing it for now and will reopen if I experience this again.\r\nThanks :) '
 'Hi @R4ZZ3,\r\n\r\nIf it is not too much of a bother, can you please help me how to resolve this error? I am exactly getting the same error where I am going as per the documentation guideline:\r\n\r\n`my_audio_dataset = my_audio_dataset.cast_column("audio_paths", Audio())`\r\n\r\nwhere `"audio_paths"` is a dataset column (feature) having strings of absolute paths to mp3 files of the dataset.\r\n\r\n'
 'I was having the same issue with this code:\r\n\r\n```\r\ndataset = dataset.map(\r\n    lambda batch: {"full_path" : os.path.join(self.data_path, batch["path"])},\r\n    num_procs = 4\r\n)\r\nmy_audio_dataset = dataset.cast_column("full_path", Audio(sampling_rate=16_000))\r\n```\r\n\r\nRemoving the "num_procs" argument fixed it somehow.\r\nUsing a mac with m1 chip'
 'Hi @Hubert-Bonisseur, I think this will be fixed by https://github.com/huggingface/datasets/pull/4614']
## Describe the bug


In OVH cloud during Huggingface Robust-speech-recognition event on a AI training notebook instance using jupyter lab and running jupyter notebook When using the dataset.cast_column("audio",Audio(sampling_rate=16_000))
method I get error

This was working with datasets version 1.17.1.dev0
but now with version 1.18.3 produces the error above.

## Steps to reproduce the bug

load dataset:

remove columns:

run my fix_path function.
This also creates the audio column that is referring to the absolute file path of the audio

Then I concatenate few other datasets and finally try the cast_column method

but get error:
