I got past this by removing repositories/k-diffusion and re-running ./launch.py. i.e.:

cd path/to/stable-diffusion-webui
conda activate web-ui
mv repositories/k-diffusion repositories/k-diffusion-old
python ./launch.py --skip-torch-cuda-test

缘由：
通过查看./repositories/k-diffusion/k_diffusion中的sampling.py发现，可能是更新的缘故，其中只含有get_sigmas_karras、get_sigmas_exponential、get_sigmas_vp。
解决方法：
在stable-diffusion-webui/modules/sd_samplers_kdiffusion.py文件第52行找到原代码：
'polyexponential': k_diffusion.sampling.get_sigmas_polyexponential将其改为'vp': k_diffusion.sampling.get_sigmas_vp即可
以上方法仅供参考

English Translation:

Cause:
By checking the sampling.py file in ./repositories/k-diffusion/k_diffusion, we found that it may be due to the update, but it only contains get_sigmas_karras, get_sigmas_exponential, and get_sigmas_vp.

Solution:
Find the original code at line 52 of stable-diffusion-webui/modules/sd_samplers_kdiffusion.py:

'polyexponential': k_diffusion.sampling.get_sigmas_polyexponential

Change it to

'vp': k_diffusion.sampling.get_sigmas_vp
