spyder doesn't launch after installing pytorch

Question

I installed pytorch but after that Spyder can no longer be launched. Here are the terminal info:

conda install pytorch torchvision -c pytorch Solving environment: done

==> WARNING: A newer version of conda exists. <== current version: 4.5.10 latest version: 4.5.11

Please update conda by running
$ conda update -n base -c defaults conda

(Spyder maintainer here) I don't know the source of this problem, but things like this can be very easily avoided if you use a conda environment to install pytorch. So my recommendation is for you to remove and reinstall Anaconda, then install Pytorch in a conda env, and finally point Spyder to your Pytorch env. — Carlos Cordoba

I don't know if you have solved your issue, but in case you have and someone else comes across this question or you haven't and are still waiting:

I came across your post as a result of having the same thing happen to me...

It would seem that all I had to do was "conda update all" for it to start working again!
