Get long message in Spyder when I use SymPy consoles

Description

What steps will reproduce the problem?

Hello! I used SymPy 1.0 in the Spyder Console and now on every input I get this long message: Output from spyder call ‘get_namespace_view’: C:\Users\rwden\AppData\Local\Programs\Spyder\pkgs\sympy\deprecated\class_registry.py:38: SymPyDeprecationWarning:

C, including its class ClassRegistry, has been deprecated since SymPy 1.0. It will be last supported in SymPy version 1.0. Use direct imports from the defining module instead. See https://github.com/sympy/sympy/issues/9371 for more info.

deprecated_since_version=‘1.0’).warn(stacklevel=2)

How can I prevent this message from appearing every time I do an input? Thank you. I am new to Spyder and it is great!

I haven’t personally noticed this issue (I don’t use Spyder) but as a maintainer of SymPy I can tell you that this warning will not be seen any more. The ClassRegistry and all associated code including the code that emits the DeprecationWarning in the OP was fully removed from the SymPy codebase in https://github.com/sympy/sympy/pull/20896

This is fixed in SymPy 1.8 which has been released some time ago. If you update to the latest SymPy with

pip install -U sympy

then you will not see this warning any more.

I’m not sure though given an issue like this what the best way is to deprecate something without warnings showing up from introspective tooling like in ipython.
