356fd5da - Improve the `run_sweep.py` script to support precision attribute (#844)

Improve the `run_sweep.py` script to support precision attribute (#844) Summary: Rename the `fp16` option to `precision`, providing 3 options: `fp32`, `fp16`, `amp`. It also adds the `precision` attribute to the result of `run_sweep.py`. Renaming the option to `precision` makes it easier to support other precisions in the future, such as `bfloat16`.
