解决datasets导入时的dill AttributeError问题

问题详情

Python 3.9.13环境下，执行import datasets报错：

AttributeError: module 'dill' has no attribute '_dill'

当前使用包版本：datasets 2.9.0、dill 0.3.6

报错堆栈：

import datasets

File "C:\ProgramData\Anaconda3\lib\site-packages\datasets\__init__.py", line 43, in <module>
    from .arrow_dataset import Dataset

File "C:\ProgramData\Anaconda3\lib\site-packages\datasets\arrow_dataset.py", line 66, in <module>
    from .arrow_writer import ArrowWriter, OptimizedTypedSequence

File "C:\ProgramData\Anaconda3\lib\site-packages\datasets\arrow_writer.py", line 27, in <module>
    from .features import Features, Image, Value

File "C:\ProgramData\Anaconda3\lib\site-packages\datasets\features\__init__.py", line 17, in <module>
    from .audio import Audio

File "C:\ProgramData\Anaconda3\lib\site-packages\datasets\features\audio.py", line 12, in <module>
    from ..download.streaming_download_manager import xopen

File "C:\ProgramData\Anaconda3\lib\site-packages\datasets\download\__init__.py", line 9, in <module>
    from .download_manager import DownloadManager, DownloadMode

File "C:\ProgramData\Anaconda3\lib\site-packages\datasets\download\download_manager.py", line 36, in <module>
    from ..utils.py_utils import NestedDataStructure, map_nested, size_str

File "C:\ProgramData\Anaconda3\lib\site-packages\datasets\utils\py_utils.py", line 602, in <module>
    class Pickler(dill.Pickler):

File "C:\ProgramData\Anaconda3\lib\site-packages\datasets\utils\py_utils.py", line 605, in Pickler
    dispatch = dill._dill.MetaCatchingDict(dill.Pickler.dispatch.copy())

AttributeError: module 'dill' has no attribute '_dill'

解决方案

方案一：降级dill版本
dill 0.3.6移除了内部的_dill模块，而datasets 2.9.0依赖该接口。执行以下命令降级：
```
pip install dill==0.3.5
```
方案二：升级datasets版本
升级到兼容dill 0.3.6的datasets版本（比如>=2.10.0，该版本已修复此依赖问题），执行命令：
```
pip install --upgrade datasets
```
