For some reason Spyder is not launching when I try to start the application. I tried to then run it through the console, but run into this error:
(base) C:\>spyder

During handling of the above exception, another exception occurred:

I've tried running
pip3 install pyqt5
but I get the same error after this installation is completed when I try to launch Spyder through the console. Any advice on this issue?
Can also mention that I tried to download PySide, but couldn't complete the installation as some other errors appeared.

I'm having trouble with Anaconda Navigator. The program isn't lauching anymore, I think it happened after I shutdown my Windows 11 and forced the program to close. When I try to launch it in the Anaconda Prompt, I have the following lines of errors:

I've tried solutions in Stackoverflow and already reinstalled the program, but nothing worked yet. If anyone can help, I will appreciate very much!
EDIT: The program returned to normal alone, don't know what happened.

The first error looks like you are missing the pyside module. Can you run
conda install PySide
or
pip install PySide
and see if this fixed that error?

PyQt5 and PySide are already installed and I still get the error. I already tried installing other spyder versions in pamac and pip but got the same error.
Thank you in advance for the help.
Looks like the python that is being used isn't the one from anaconda:
File "/usr/lib/python3.8/site-packages/qtpy/__init__.py"
Try doing the following:
Inside your terminal write:
// this will deactivate the base environment
// you will need to: "conda reactivate" later to use spyder again
conda deactivate
then do:
pip install PyQt5 PySide
then:
conda activate
spyder
I just installed Anaconda3-2020.02 on my Windows 10 computer but the Anaconda navigator GUI is not running when I launched it the same problem with Spyder. The following error was reported in the command line:
Traceback (most recent call last): File "C:\ProgramData\Anaconda3\lib\site-packages\qtpy__init__.py", line 204, in from PySide import version as PYSIDE_VERSION # analysis:ignore ModuleNotFoundError: No module named 'PySide'

Any ideas as to what the problem might be and how to solve it will be appreciated.
I have created an environment in Anaconda using environment.yml file. After activating the environment when I try to open Spyder IDE it shows up the following error message.

I am unable to sort it out using all previous suggested solutions on using other gcc versions.
Thanks in advance.
