same error here. Running the training step

python main.py --base configs/stable-diffusion/v1-finetune_unfrozen.yaml 
                -t 
                --actual_resume /path/to/original/stable-diffusion/sd-v1-4-full-ema.ckpt  
                -n <job name> 
                --gpus 0, 
                --data_root /root/to/training/images 
                --reg_data_root /root/to/regularization/images 
                --class_word <xxx>

I think the issue is the main.py is wrapped in a massive try catch and if there is an exception before defining the trainer instance, well, it just explodes with a non descriptive error.

In my case, the TestTubeLogger setup by default in this repo config is not supported anymore by pytorch lighting.

Changing this line and this line to CSVLogger

UPDATE just do yourself a favor and install a fairly old version of pytorch lighting 1.5.9, it will fix this issue and other ones you will see.

what's the code that gave you this error

I am having this exact same error code, however installing the older version of pytorch-lightning hasn't fixed the issue. any other ideas would be much appreciated!!

Deleting the Conda Enviroment, reinstalling SD, and copying(replacing some 70ish files) the dreambooth repo into the SD one fixed it for me.
