Hi,
  Your observation is correct. I have fixed this in the latest version (did not fix the old).

-bash-4.1$ module purge
-bash-4.1$ module load python3/3.7.0  
-bash-4.1$ python3 -c "import lzma;"
-bash-4.1$ python3 -c "import lzma;print(lzma.__file__)"
/cluster/software/VERSIONS/python3-3.7.0/lib/python3.7/lzma.py
