Actually, also importing both onnx and torch causes Python to crash: $ python3 Python 3.13.11 (main, Dec 8 2025, 11:43:54) [GCC 15.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import torch >>> import onnx [libprotobuf ERROR google/protobuf/descriptor_database.cc:642] File already exists in database: onnx/onnx-ml.proto [libprotobuf FATAL google/protobuf/descriptor.cc:1988] CHECK failed: GeneratedDatabase()->Add(encoded_file_descriptor, size): terminate called after throwing an instance of 'google::protobuf::FatalException' what(): CHECK failed: GeneratedDatabase()->Add(encoded_file_descriptor, size): Abandon python3
So, let's reassign this bug to the shared factor: python3-onnx (even if I'm not sure where exactly is the bug).
