Pip install torch error

$ python3 -V
Python 3.4.3

Ubuntu

When I pip install torch, I receive this error:

ERROR: Could not find a version that satisfies the requirement torch==1.2.0+cu92 (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2)
ERROR: No matching distribution found for torch==1.2.0+cu92

Does anyone know the reason?
