Can you share a bit about the version of dss you are using (9.0.4 and 9.0.5 are the most recent versions.) Can you share a bit about the type of model you are trying to export. It appears you might be trying to export a random forest. (However, there might be challenges with exporting neural networks or custom models.) Also are you using any script steps. (Based on some challenges I’ve run into in the past, It’s my sense that some script steps can not be converted directly to python.)
If you can share some of these details it might help others who have succeeded or had similar problems help out.
