Direzione di ricerca

Start by reproducing the failure with the provided bazel run command and inspect lingvo/core/ops/__init__.py, which loads x_ops.so. Trace how that shared library is built and which TensorFlow version it links against; the reported undefined symbol indicates a compatibility failure. Done means the command starts without the import or symbol error in a supported environment.
