ImportError: cannot import name 'Sequence' from 'collections' (C:\Users\86156\.conda\envs\insar\lib\collections\__init__.py)

ImportError: cannot import name 'Sequence' from 'collections' (C:\Users\86156\.conda\envs\insar\lib\collections\__init__.py) 这个错误是因为在你的代码中引用了collections模块中的Sequence，但是Python解释器无法找到该名称。

解决这个问题的方法是从collections.abc模块中导入Sequence而不是直接从collections中导入。这是因为在Python 3.3及以后的版本中，Sequence应该从collections.abc模块中导入而不是从collections中导入。从Python 3.7开始，如果你仍然从collections中导入Sequence，Python会打印一个警告信息。在Python 3.9中，将必须从collections.abc中导入Sequence。

所以，你可以将你的代码中的导入语句修改为：

from collections.abc import Sequence

这样就可以解决ImportError: cannot import name 'Sequence' from 'collections'的问题了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
