ValueError: Multiple tensors as index not yet supported

[zrx0311]

I installed web-stable-diffusion according to the official documentation, but it couldn't run. It seemed to be caused by changes in relax.

/web-stable-diffusion# python3 build.py --target cuda

is outdated. steps_offset should be set to 1 instead of 0. Please make sure to update the config accordingly as leaving steps_offset might led to incorrect results in future versions. If you have downloaded this checkpoint from the Hugging Face Hub, it would be very nice if you could open a Pull request for the scheduler/scheduler_config.json file

Set TORCH_LOGS="+dynamo" and TORCHDYNAMO_VERBOSE=1 for more information

You can suppress this exception and fall back to eager by setting:
import torch._dynamo
torch._dynamo.config.suppress_errors = True

Thank you so much！

I'm hitting this as well, after making several updates to the code which are helping to enable SDXL. Do you know how this can be fixed, or have any hints?
