[Bug]: Some lora can not be loaded after latest commit

[VantomPayne]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What happened?

After pulling the latest commit, certain loras are not loaded during generation, instead gives error in console:

activating extra network lora with arguments [<modules.extra_networks.ExtraNetworkParams object at 0x000001A66D7BEBF0>, <modules.extra_networks.ExtraNetworkParams object at 0x000001A66D7BCCD0>]: Exception Traceback (most recent call last): File "F:\stable-diffusion-webui\modules\extra_networks.py", line 75, in activate extra_network.activate(p, extra_network_args) File "F:\stable-diffusion-webui\extensions-builtin\Lora\extra_networks_lora.py", line 17, in activate lora.load_loras(names, multipliers) File "F:\stable-diffusion-webui\extensions-builtin\Lora\lora.py", line 151, in load_loras lora = load_lora(name, lora_on_disk.filename) File "F:\stable-diffusion-webui\extensions-builtin\Lora\lora.py", line 83, in load_lora sd = sd_models.read_state_dict(filename) File "F:\stable-diffusion-webui\modules\sd_models.py", line 220, in read_state_dict pl_sd = safetensors.torch.load_file(checkpoint_file, device=device) File "F:\stable-diffusion-webui\venv\lib\site-packages\safetensors\torch.py", line 98, in load_file with safe_open(filename, framework="pt", device=device) as f: Exception: Error while deserializing header: InvalidHeaderDeserialization

I have noticed that newer Loras still work, so it's possible the "pre-0.40" lora fix broke during the last commit.

Steps to reproduce the problem

1. Load lora of choice (older ones tend to produce this problem in my instance) via either the extention method or the new cards method.
2. Press Generate
3. Generation should still work, but lora has no effect, console shows error provided above.

What should have happened?

All loras should load properlly.

@VantomPayne did you find a workaround for this? I think I'm having the same issue running on debian. super strange.

The same problem, kaggle. Very annoying :(

Same Problem some works and others just dont

This LoRA: https://civitai.com/models/6526/studio-ghibli-style-lora?commentId=20654&modal=commentThread didn't work for me on some commits but did on 7a14c8ab45da8a681792a6331d48a88dd684a0a9

hi all. Same problem. LORA trained through the latest version of Dreambooth gives this error. The log gives the same output, only the type of error at the end is different: "TypeError: pop expected at most 1 argument, got 2"

I've been having the same problem and it seems to be tied to a specific LORA, so far I reproduced the error by creating 4 images that turned more distorted every time, then had to do a full restart that seemed to temporarily "fix" the issue. The only thing closer to a solution is just avoiding the LORA.

The error in OP likely indicates the file is corrupted.

Exception: Error while deserializing header: InvalidHeaderDeserialization

Extra networks have been refactored as of https://github.com/AUTOMATIC1111/stable-diffusion-webui/commit/b75b004fe62826455f1aa77e849e7da13902cb17, so a new issue should be opened if the problem persists.
