I tried to install tensorflow version v2.7 for same python version 3.6, but it is giving error as ERROR: Failed building wheel for h5py
After that i checked the below discussion to resolve h5py problem
and i follow the step for Python 3.6+JetPack4.6.3 then also i am getting h5py issue Failed to build h5py ERROR: Could not build wheels for h5py, which is required to install pyproject.toml-based projects
