报错 ImportError: cannot import name ‘Sequence‘ from ‘collections‘

环境：python3.10

问题：

File "G:\research\code\MicroDE_py\plot_bcic_iv_4_ecog_trial.py", line 262, in
    from skorch.helper import predefined_split
  File "C:\Users\Lenovo\.conda\envs\braindecode\lib\site-packages\skorch\helper.py", line 6, in
    from collections import Sequence
ImportError: cannot import name 'Sequence' from 'collections' (C:\Users\Lenovo\.conda\envs\braindecode\lib\collections\__init__.py)

解决：

将报错的代码句子：

from collections import Sequence

修改为：

from collections.abc import Sequence

程序可以成功运行。

原理：

Sequence should be imported from collections.abc instead of collections since Python 3.3. A warning is printed starting with Python 3.7 and in Python 3.9 the new import location will be required.

This PR imports from collections.abc while still falling back to importing from collections for older Python versions.

翻译：

Sequence应该从Python 3.3 开始collections.abc而不是从collections开始导入。从 Python 3.7 开始打印警告，在 Python 3.9 中将需要新的导入位置。

此 PR 导入自，collections.abc同时仍回退到从collections旧 Python 版本导入。
