streamlit TypeError: Plain typing.NoReturn is not valid as type argument

streamlit TypeError: Plain typing.NoReturn is not valid as type argument

今天在运行streamlit 程序的时候出现了下面的问题：

raceback (most recent call last): File "/usr/local/python3.7.0/lib/python3.7/runpy.py", line 183, in _run_module_as_main mod_name, mod_spec, code = _get_module_details(mod_name, _Error) File "/usr/local/python3.7.0/lib/python3.7/runpy.py", line 142, in _get_module_details return _get_module_details(pkg_main_name, error) File "/usr/local/python3.7.0/lib/python3.7/runpy.py", line 109, in _get_module_details __import__(pkg_name) File "/usr/local/python3.7.0/lib/python3.7/site-packages/streamlit/__init__.py", line 70, in from streamlit.delta_generator import DeltaGenerator as _DeltaGenerator File "/usr/local/python3.7.0/lib/python3.7/site-packages/streamlit/delta_generator.py", line 168, in DataFrameSelectorMixin, File "/usr/local/python3.7.0/lib/python3.7/site-packages/streamlit/delta_generator.py", line 303, in DeltaGenerator def __getattr__(self, name: str) -> Callable[..., NoReturn]: File "/usr/local/python3.7.0/lib/python3.7/typing.py", line 755, in __getitem__ return self.__getitem_inner__(params) File "/usr/local/python3.7.0/lib/python3.7/typing.py", line 251, in inner return func(*args, **kwds) File "/usr/local/python3.7.0/lib/python3.7/typing.py", line 774, in __getitem_inner__ result = _type_check(result, msg) File "/usr/local/python3.7.0/lib/python3.7/typing.py", line 135, in _type_check raise TypeError(f"Plain {arg} is not valid as type argument")TypeError: Plain typing.NoReturn is not valid as type argument

解决方法

可能3.7.0最新版不太支持，我们会退streamlit版本：

pip install streamlit==1.9
