How to install older version of pytorch?

A:

pip install torch==

Collecting torch==

ERROR: Could not find a version that satisfies the requirement torch== (from versions: 0.1.2, 0.1.2.post1, 0.4.1, 1.0.0, 1.0.1, 1.0.1.post2, 1.1.0)
      ERROR: No matching distribution found for torch==

This means that version 0.2 is not available 
You can download the specific version (wheels seem available) and install it with pip install
