You can also update `datasets`:

```
pip install -U datasets
```

It will also update `fsspec` to use the right version

This seems to work fine in 2.19.0. Hopefully it will not break again

Hi, just wished to follow up on this issue. I am recently using datasets==2.12.0 and fsspec==2023.9.2 and the same error: "NotImplementedError: Loading a streaming dataset cached in a LocalFileSystem is not supported yet." popped up. I tried doing upgrading datasets to the latest version with `pip install -U datasets` and the same issue occurred.

### Describe the bug

Loading a streaming dataset with this version of fsspec fails with the following error:

`NotImplementedError: Loading a streaming dataset cached in a LocalFileSystem is not supported yet.`

I suspect the issue is with this PR 

https://github.com/fsspec/filesystem_spec/pull/1381

### Steps to reproduce the bug

1. Upgrade fsspec to version `2023.10.0`
2. Attempt to load a streaming dataset e.g. `load_dataset("laion/gpt4v-emotion-dataset", split="train", streaming=True)`
3. Observe the following exception:

```
  File "/opt/hostedtoolcache/Python/3.11.6/x64/lib/python3.11/site-packages/datasets/load.py", line 2146, in load_dataset
    return builder_instance.as_streaming_dataset(split=split)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/opt/hostedtoolcache/Python/3.11.6/x64/lib/python3.11/site-packages/datasets/builder.py", line 1318, in as_streaming_dataset
    raise NotImplementedError(
NotImplementedError: Loading a streaming dataset cached in a LocalFileSystem is not supported yet.
```

### Expected behavior

Should stream the dataset as normal.

### Environment info

datasets@main
fsspec==2023.10.0
