AttributeError: 'FakeInitialModel' object has no attribute 'sd_checkpoint_info' on ForgeUI

I'm getting the error "AttributeError: 'FakeInitialModel' object has no attribute 'sd_checkpoint_info'" when trying to generate.

Here is cmd reply:

I'm also attaching the settings I chose for the grid:

Btw, I have a model selected and it generates fine without the script enabled. Any way to fix this?

How about trying to delete the \extensions\sd-infinity-grid-generator-script\scripts_pycache_ folder?

It worked for me in my environment.
But, I feel like model switching might not be possible on Forge.

Got it working!!! This drove me nuts while trying to troubleshoot it for several hours.

Go to this folder \extensions\sd-infinity-grid-generator-script\scripts:

Edit the infinity_grid.py file with your text editor of choice and go to line 304. It should look like this:

"model": choose_better_file_name('', shared.sd_model.sd_checkpoint_info.model_name).replace(',', '').replace(':', ''),

Change the value to opts.sd_model_checkpoint and save your changes:

"model": opts.sd_model_checkpoint,

If you already have ForgeUI running, end the running process along with closing the local web page. Relaunch ForgeUI and hopefully that should do the trick 🙏

I modified the code according to your method. Error no longer occurs. But during the plugin's operation, it does not load and switch models according to the yaml file I set. Instead, it continues to use the model selected in the top-left corner of ForgeUI. I cannot find out how to fix this😫
