Start by reproducing the import using the reported Python 3.6, tensorflow-gpu 2.0.0, and tensorflow-probability versions, then inspect the traceback showing the missing tensorflow_probability.python.internal module. Done means identifying a reproducible package or version issue and confirming that importing tensorflow_probability succeeds with the supported dependency combination.
