Hi @my0828, this seems to be a follow-up discussion from #727. While I appreciate the effort to keep separate issues in separate discussions, we would need much the same information here as we did in the last one, so we could also continue resolving your errors there. With all errors, you can ensure to receive the help you want faster and more precise by being as accurate as you can be. An accurate error message includes:

• which code you are trying to run (all relevant commands up to and including the one causing the error)
• which error message you receive (as complete as possible)
• which version of the code you are using (message-ix show-versions is our convenience tool for that)

By including this information, the community can understand quicker what exactly your problem is and how to reproduce it on our own systems. This helps us figuring out a solution that we can then share with you.
