We are trying to load an IR model from a memory buffer (loaded from a single binary file, not relevant) but dnn::readNet() for dldt from buffer is not implemented.

 else if (framework == "dldt")
        CV_Error(Error::StsNotImplemented, "Reading Intel's Model Optimizer models from buffers");

My colleague is already working on submitting a pull request to implement this.
