instructions on how to disable this automatic conversion if for some reason you prefer not to use it.
Automatic Mixed Precision
You can use automatic mixed precision with either a pytorch-like AMP way or the apex-like way:
To configure pytorch AMP-like mode set:
json
{
    "fp16": {
        "enabled": "auto",
        "loss_scale": 0,
        "loss_scale_window": 1000,
        "initial_scale_power": 16,
        "hysteresis": 2,
        "min_loss_scale": 1
    }
}
and the [Trainer] will automatically enable or disable it based on the value of
args.fp16_backend. The rest of config values are up to you.
This mode gets enabled when --fp16 --fp16_backend amp command line args are passed.
You can also enable/disable this mode explicitly:
json
{
    "fp16": {
        "enabled": true,
        "loss_scale": 0,
