Any idea ?

Thank you for your answers.

Best regards.

You can start by using a stable version of Python. You are using version 3.13 (which is Aplha?).
At least Robot Framework is known to be compatible with version 3.12.

Hello Helio,

Thank u for your reply.

I use RF with version 7.0.

Version of Python : 3.13.0a5 on win32 (–> Alpha = 0a5 I guess)

I think the version of RF is full compatible with Python.

Best regards.

Do u think I should install Python 3.12 instead of 3.13 ?

Finally it works fine with Python 3.12.
Thank u Helio

Just an FYI:

From that version “3.13.0a5”, “3.13.0” is the version number the “a5” is the 5th alpha pre-relese version of “3.13.0”, after the alpha versions comes the beta versions b1, b2, etc and then the release candidates rc1, rc2, etc and then eventually the stable release version which will be just “3.13.0”

If you are running an alpha or beta version expect things to not work, they are not for normal use, they are for python development team to test the new version of python (and anyone else who wants to)

If you run a rc version you can expect most things to work but still should expect that might encounter bugs.

If you just want python to work and you just want robot framework to work so you can test the software you want to test then you should stick with stable python and robot framework versions, stay away from alphas, betas and release candidates.

Dave.
