For the meantime add the following line before utility.has_run = True in the notebook:

!echo "fastapi==0.90.1" >> /content/stable-diffusion-webui/requirements_versions.txt

So it looks like similar to the following:

  !sed -i -e '''/    prepare_environment()/a\    os.system\(f\"""sed -i -e ''\"s/self.logvar\\[t\\]/self.logvar\\[t.item()\\]/g\"'' /content/stable-diffusion-webui/repositories/stable-diffusion-stability-ai/ldm/models/diffusion/ddpm.py""")''' /content/stable-diffusion-webui/launch.py
  !sed -i -e '''/    prepare_environment()/a\    os.system\(f\"""sed -i -e ''\"s/dict()))$/dict())).cuda()/gm\"'' /content/stable-diffusion-webui/repositories/stable-diffusion-stability-ai/ldm/util.py""")''' /content/stable-diffusion-webui/launch.py
  !echo "fastapi==0.90.1" >> /content/stable-diffusion-webui/requirements_versions.txt  
  utility.has_run = True 

Can't update atm since I'm at my phone lol, regardless thanks for reporting!
