“–reset don’t solve the problem.”

From ;what you posted,
You’re missing files, likely entire modules.

You should closely watch and perhaps inspect the installation log.
I don’t use spyder3, so I’m not familiar with the documentation which might describe how to troubleshoot.
Without looking at the installation log, I can only wildly speculate but the most common cause I’ve found for this kind of problem is related to building, which typically means GCC versions, and other build tools.

There is also a separate documentation package
https://software.opensuse.org/package/spyder3-doc

I had the same problem. Apparently the module “cloudpickle” is not installed as dependency (I didn’t check if it is listed).

The search zypper se “cloudpickle” gives

python2-cloudpickle
python3-cloudpickle

I installed the python3, then from terminal spyder3 --reset.

Spyder should start normally then.

now I have this problem.
