Hey @javierdelpino, thanks for reporting. It seems your MUSICNN is broken. One option to fix it is for you to close Spyder, open the Anaconda Prompt and run the following commands there:

conda activate MUSICNN
conda install typing-extensions=3.7

and then restart Spyder again.

That should work as long you haven't installed packages with pip in that env because conda can't easily deal with that situation. If that was the case, then I'm afraid you'll have to recreate your environment to fix this error.

Let us know if you manage to solve your problem.
