Hi! I’m trying to run Logistic Regression Training Examples using OpenFHE from [GitHub - openfheorg/openfhe-logreg-training-examples: OpenFHE-Based Examples of Logistic Regression Training using Nesterov Accelerated Gradient Descent](https://github.com/openfheorg/openfhe-logreg-training-examples), and then I run ./lr\_nag by default, I see this:

It is a known bug in v1.1.4. There is a github issue for it: [EvalSumRowsKeyGen()/EvalSumColsKeyGen() incorrect behavior · Issue #773 · openfheorg/openfhe-development · GitHub](https://github.com/openfheorg/openfhe-development/issues/773) We will fix it in v1.2.0 (to be released within 2-3 weeks). It works correctly in v1.1.2. Also, there are multiple topics on this bug in the Discourse forum, e.g., [Error in EvalSumRows "Input evaluation key map is empty" - #3 by ManhBui](https://openfhe.discourse.group/t/error-in-evalsumrows-input-evaluation-key-map-is-empty/1186/3)
