Did you try with pytorch lightning==1.6.1? The problem arised for me when my pytorch lightning is 1.7.0 and above

The actual issue isn't with trainer being undefined, it's in the try block that precedes it. Remove all the code in the try block out of it, and rerun the code to see what the caught error is.

For me it was FileNotFoundError: [Errno 2] No such file or directory: 'configs/first_stage_models/vq-f4/model.yaml' which I fixed with this: https://github.com/CompVis/latent-diffusion/issues/87#issuecomment-1413467280
