我刚刚将 Python 更新到版本
3.10.8我必须重新安装很多软件包，但现在当我尝试加载 HuggingFace 模型的标记生成器时出现错误
这是我的代码：
# Import libraries
from transformers import pipeline, AutoTokenizer
# Define checkpoint
model_checkpoint = 'deepset/xlm-roberta-large-squad2'
# Tokenizer
tokenizer = AutoTokenizer.from_pretrained(model_checkpoint)
请注意，
transformers4.24.0这是我得到的错误：

我尝试了多种解决方案（例如，this和this），但似乎都不起作用。
根据这个链接，我应该将
collections.Mappingcollections.abc.Mapping另一个可能的解决方案是将 Python 降级到 3.9，但我想将其保留为最后的手段。
我该如何解决这个问题？
原来是与
protobuf4.21.9这将错误更改为：
TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).
More information: https://developers.google.com/protocol-buffers/docs/news/2022-05-06#python-updates
所以我将
protobuf3.20.0欲了解更多详情，请查看此处。
我在 2024 年 1 月 5 日也遇到同样的错误。我正在使用最新版本的 protobuf (5.27.0)，我必须将其降级回 3.20.x，以便我可以加载我的分词器。
