Excuse me, by reading the readme file, I know that the model should be trained first, but when I run ddpm_ Train reported such an error
FileNotFoundError: [Errorno 2] No such a file or directory: ‘experiments/ddpm-RS-Unet_220819_161634
I don't know where I made a mistake, I would be grateful if you could reply

Hi @wo0423
Yes, you can start with training the diffusion model first if you wish (however, this may take several days to train), or else you can use the pre-trained diffusion model provided (I strongly recommend you to use the pre-trained diffusion model first). Can you pls copy and paste the full error details here?

firstly，thx for your reply.i set the resume_state in “path”: "E:/I190000_E97_opt.pth" in the cdd.json,but when i run the ddpm_cd file, a similar error occured
E:\anaconda\ana\python.exe E:/ddpm-cd-master/ddpm_cd.py

@wo0423 The code assumes you save your pre-trained diffusion model in the experiments folder, as you can see from the error msg.

• So, pls create a folder named experiments inside ddpm-cd-master (or any other location you wish to save the results).
• Then create ddpm-RS-Unet_220426_160536/checkpoint/ inside experiments and place both I190000_E97_opt.pth and I190000_E97_gen.pth in it.
• In the config file you should mention only the first part of the pre-trained model (omit _opt.pth and/or _gen.pth, the code will automatically take care of it), i.e. experiments/ddpm-RS-Unet_220426_160536/checkpoint/I110000_E88.
• The results will be saved in experiments.

I hope this will resolve your issue.
Also, I see that you run the code on the windows machine. In windows, we need to specify path using \ whereas in my code running on linux machine uses /. Pls change those also.
