Error while trying merging 2 models

Error_Trying_Merge_Models.txt

Hello folks!

Trying the feature for merging models as described in "What's new section" of Easy Diffusion,
I always get the error "positional argument follows keyword argument", as attached in this message.

Any help would be priceless...

Thanks a lot...

Try to ommit the ratio= and use_fp16= prefixes:

m0 = 'D:/stable-diffusion-ui/models/stable-diffusion/peterpolach.ckpt'
m1 = 'D:/stable-diffusion-ui/models/stable-diffusion/Double_Exposure_v2.ckpt'
out = 'D:/stable-diffusion-ui/models/stable-diffusion/mergedpolachdouble.ckpt'
merge_models(m0, m1, 0.3, out, True)

I moved the pathes to variables for readability, you can pass them directly if you want.

With this:

merge_models('D:/stable-diffusion-ui/models/stable-diffusion/peterpolach.ckpt', 'D:/stable-diffusion-ui/models/stable-diffusion/Double_Exposure_v2.ckpt', 0.5, 'D:/stable-diffusion-ui/models/stable-diffusion/mergedpolachdouble.ckpt', True)

I get this now:

Traceback (most recent call last):
File "", line 1, in

There is a pull request to fix this bug. map_location="cpu" is wrong here. It needs to be merged to fix this.

Does merge_models('D:/stable-diffusion-ui/models/stable-diffusion/peterpolach.ckpt', 'D:/stable-diffusion-ui/models/stable-diffusion/Double_Exposure_v2.ckpt', 0.5, 'D:/stable-diffusion-ui/models/stable-diffusion/mergedpolachdouble.safetensors', True) work?

Hi JeLuf...

Well... with '.safetensors' extension, it works like a charm...!

Thanks

[JeLuF]

You should use safetensors anyway :-) In contrast to ckpt, it can not contain executable code.
