Error Message Summary:

NotFoundError: Input variable(tmp_163) cannot be found in scope for operator 'Fetch'.Confirm that you have used the fetch Variable format instead of the string literal('tmp_163') in fetch_list parameter when using executor.run method. In other words, the format of executor.run(fetch_list=[fetch_var])(fetch_var is a Variable) is recommended. [Hint: fetch_var should not be null.] at (/paddle/paddle/fluid/operators/controlflow/fetch_op.cc:82) [operator < fetch > error]
