This trainer is returning just black images, which is strange because a couple of weeks ago it was working just fine. Any ideas or alternatives?

I don't know.. Is there differences of outcome between other alpha numbers?

The Trainer is currently broken. It has been for a few days now. The Creator is aware of the issue and is actively working on the issue.

Using an Alpha of 1 is not the intended behavior of the trainer. All setting the Alpha to 1 does is allow the trainer to train a model under the current broke condition. It will affect the quality of your project.

Just wait for it to be fixed.
