Describe the bug

File "/usr/local/lib/python3.10/dist-packages/torch/utils/_device.py", line 79, in __torch_function__ return func(*args, **kwargs) torch.OutOfMemoryError: CUDA out of memory. Tried to allocate 2.32 GiB. GPU 0 has a total capacity of 79.25 GiB of which 2.27 GiB is free. Including non-PyTorch memory, this process has 0 bytes memory in use. Of the allocated memory 36.46 GiB is allocated by PyTorch, and 20.98 MiB is reserved by PyTorch but unallocated. If reserved but unallocated memory is large try setting PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True to avoid fragmentation. See documentation for Memory Management (https://pytorch.org/docs/stable/notes/cuda.html#environment-variables)

You need to use --tp-size [#_OF_DEVICES] to enable tensor parallelization. Otherwise SGL will only use 1 GPU by default

thank you so much. it works like charm: not sure if i can do anything that can make it faster
