【以下回答由 GPT 生成】
根据异常信息，导入datasets模块时发生了异常。具体为在datasets.arrow_writer中找不到名为ParquetWriter的引用。
解决这个问题的方法是确保datasets库已正确安装，并且版本兼容。可以尝试以下步骤来解决问题：
Step 1: 确认datasets库已正确安装。 以管理员身份运行以下命令来安装datasets库：
pip install datasets
Step 2: 更新datasets库至最新版本。 如果已经安装了datasets库，但是版本较旧，可以尝试更新至最新版本：
pip install --upgrade datasets
Step 3: 检查datasets.arrow_writer模块是否存在ParquetWriter引用。 查看datasets.arrow_writer模块的代码，确认是否存在ParquetWriter引用。如果不存在，那可能是库的版本兼容性问题。
如果以上步骤都没有解决问题，还可以尝试以下额外的解决方法：
额外解决方法: 查找相关的错误报告和讨论。 在搜索引擎中搜索异常信息和关键词，查找是否有其他人遇到了类似的问题，并且是否有解决方案或者错误报告。
如果以上解决方法都没有解决问题，那可能是一个bug或者编程错误。建议联系datasets库的开发者或者社区，提问并报告该问题。
