Ambiguous License

README.md says:

This project is licensed under the terms of the GPL v2 license.

LICENSE says:

ACADEMIC OR NON-PROFIT ORGANIZATION NONCOMMERCIAL RESEARCH USE ONLY

Which one is the correct license for your code?

I'd like to see if our team is permitted to use your code in our work of deep-learning related evaluation.
If the later one (LICENSE) is correct, meaning of "NONCOMMERCIAL" looks somewhat ambiguous to me.

For example, does it violate the license to use your code for evaluation of a proprietary DNN processing LSI and reveal the result to our customer?
Or, is it permitted to use the code for a feasibility study of DNN processing LSI at an R&D department, whose result might be published as an academic paper?

Where is the boundary between commercial and non-commercial uses in your point of view?
