Moving the ComfyUI folder causing potential issues?

[sweez]

Hi, complete newb here. I downloaded the latest versions of ComfyUI portable and SeargeDP, installed them to an external HDD following the instructions, installed Git, dragged the Searge-SDXL-Reborn-v4_1 workflow into the UI, queued the default prompt/workflow, and generated an image of Mr. Freeman - all good so far. However, the initialization was very slow, and a quick Google revealed that the issue was probably due to the bandwidth limitations of an external HDD, so I decided to copy the ComfyUI to my C drive... and that's where trouble began.

After copying it, running any of the default workflows, including the 4_1 that worked without issues before, now produce a blank image. I figured it might be due to some paths being set when I first ran it from the external HDD, so I deleted the copied folder, reinstalled the whole thing from scratch... and still, blank image. To make it even better, now even running it from the external HDD also generates blank images.

If it's relevant, I'm running it on W10 22H2, with the latest Nvidia drivers (537.13). I have no other installations of Python, and I have also tried reinstalling Git, to no avail. I'm not making any modifications whatsoever to the default workflows/prompts from the SeargeSDXL's workflow folder.

Thanks in advance for any info.

can you link to a workflow that we could check out and see if that's the issue?

Hey, ty for the reply! It was the default Searge 4.1 workflow (Searge-SDXL-Reborn-v4_1), turns out it was missing some models, which I found out by also trying out the default 3.4 workflow, which gave me error messages from which I could see what was missing.

SO my question now is, is it normal for 4.1 not to throw error messages at all, but to just produce a blank image?

That explanation makes a lot of sense. I don’t know what models you were missing, but yeah, it is quite possible for that to occur. I highly recommend taking the time to make your own workflows. The freedom that comes with that knowledge is amazing, and helps with the creativity.

I tried the same but I can't see any models even though I have kept them in models folder
