I think you just need to remove /anaconda3 to uninstall Anaconda. By the way, the first line of the error you posted above clearly shows that you corrupted your Anaconda installation by using pip and conda at the same time to install PyQt 5. Now you really need to reinstall it to fix this problem. And for next, don't use pip to install a package that you can install with conda, because this problem will appear again.

The first line of your error message is quite clear and telling. You have two versions of PyQt5 in your environment, and the first one in the error was installed with pip. You need to remove that one and the error should be fixed
