ngen ( C++ ) is calling setenv() after Python has already initialized os.environ, and Python’s os.environ mapping is not automatically refreshed when the environment is mutated from C/C++.
So Python keeps an internal view of the environment that includes things set before Python started (like NGEN_RESULTS_DIR), but not variables injected later from C++ (like NGEN_LOG_FILE_PATH).
Added a helper method to ensure the Python os environment is not stale when LSTM runs.
