[Bug]: D:\stable-diffusion2\automatic\modules\processing.py:733: RuntimeWarning: invalid value encountered in cast x_sample = x_sample.astype(np.uint8)

Is there an existing issue for this?

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

What happened?

I got RuntimeWarning: invalid value encountered in cast x_sample = x_sample.astype(np.uint8) trying to use a lora trained by https://github.com/bmaltais/kohya_ss which is also the newest version v21.8.7 with these settings https://www.mediafire.com/file/p7hc4q8n7wuu31z/CharacterLoraSettings.json/file. The output in the web ui is also just black too but the samples from kohya look fine. Any other lora works just fine and dose not have that error or issue, just the ones I train.

Steps to reproduce the problem

Go to ....
Press ....
... load my lora tell it to produce an image

What should have happened?

It should have not given me that error or just a black output.
