load_dataset save_to_disk load_from_disk error
solved.
fsspec version problem I'm using the latest datasets and fsspec  , but still got this error!

datasets : Version: 2.13.0

fsspec   Version: 2023.10.0

```
File "/home/guoby/app/Anaconda3-2021.05/envs/news/lib/python3.8/site-packages/datasets/load.py", line 1892, in load_from_disk
    return DatasetDict.load_from_disk(dataset_path, keep_in_memory=keep_in_memory, storage_options=storage_options)
  File "/home/guoby/app/Anaconda3-2021.05/envs/news/lib/python3.8/site-packages/datasets/dataset_dict.py", line 1371, in load_from_disk

  File "/home/guoby/app/Anaconda3-2021.05/envs/news/lib/python3.8/site-packages/datasets/arrow_dataset.py", line 1639, in load_from_disk
    fs_token_paths = fsspec.get_fs_token_paths(dataset_path, storage_options=storage_options)
  File "/home/guoby/app/Anaconda3-2021.05/envs/news/lib/python3.8/site-packages/fsspec/core.py", line 610, in get_fs_token_paths
    chain = _un_chain(urlpath0, storage_options or {})
  File "/home/guoby/app/Anaconda3-2021.05/envs/news/lib/python3.8/site-packages/fsspec/core.py", line 325, in _un_chain
    cls = get_filesystem_class(protocol)
  File "/home/guoby/app/Anaconda3-2021.05/envs/news/lib/python3.8/site-packages/fsspec/registry.py", line 232, in get_filesystem_class
    raise ValueError(f"Protocol not known: {protocol}")
``` These two versions work.

 datasets==2.10.1 and fsspec==2023.6.0 also works for me. 确实
### Describe the bug

datasets version： 2.10.1
I `load_dataset `and `save_to_disk` sucessfully on windows10( **and I `load_from_disk(/LLM/data/wiki)` succcesfully on windows10**), and I copy the dataset `/LLM/data/wiki`
into a ubuntu system, but when I `load_from_disk(/LLM/data/wiki)` on ubuntu,  something weird happens:


```
load_from_disk('/LLM/data/wiki')
  File "/usr/local/miniconda3/lib/python3.8/site-packages/datasets/load.py", line 1874, in load_from_disk
    return DatasetDict.load_from_disk(dataset_path, keep_in_memory=keep_in_memory, storage_options=storage_options)
  File "/usr/local/miniconda3/lib/python3.8/site-packages/datasets/dataset_dict.py", line 1309, in load_from_disk
    dataset_dict[k] = Dataset.load_from_disk(
  File "/usr/local/miniconda3/lib/python3.8/site-packages/datasets/arrow_dataset.py", line 1543, in load_from_disk
    fs_token_paths = fsspec.get_fs_token_paths(dataset_path, storage_options=storage_options)
  File "/usr/local/miniconda3/lib/python3.8/site-packages/fsspec/core.py", line 610, in get_fs_token_paths
    chain = _un_chain(urlpath0, storage_options or {})
  File "/usr/local/miniconda3/lib/python3.8/site-packages/fsspec/core.py", line 325, in _un_chain
    cls = get_filesystem_class(protocol)
  File "/usr/local/miniconda3/lib/python3.8/site-packages/fsspec/registry.py", line 232, in get_filesystem_class
    raise ValueError(f"Protocol not known: {protocol}")
ValueError: Protocol not known: /LLM/data/wiki
```
It seems that something went wrong on the arrow file?
How can I solve this , since currently I can not save_to_disk on ubuntu system
