@Andreas This bug report has been forwarded to you via the IBM Bugzilla. Therefore, you can get an openSUSE VM for development (not only Fedora) by IBM. Fedora is the partner community of openSUSE, and we are supporting each other. Please fix the bug on openSUSE Tumbleweed. As soon as python-onnx is working on openSUSE, it will be enabled for builds on Fedora also again.
