error when use try to use int8 operations with OpenCLIP.

[xiaohoua]

I am trying to quantify open_clip's pre-trained model and then do a zero sample classification test on clip_benchmark. But get an error:
AttributeError: module 'triton.language' has no attribute 'libdevice'
Here's my code：

import open_clip
import bitsandbytes as bnb

def quantize_clip(model_name: str = "ViT-B-32-quickgelu", pretrained: str = "laion400m_e32", cache_dir: str = None, device="cpu", **kwargs):
    print("====quantize clip====")
    model, _, transform = open_clip.create_model_and_transforms(model_name, pretrained=pretrained, cache_dir=cache_dir)
    int8_linear_layer = bnb.nn.triton_based_modules.SwitchBackLinear
    int8_model = open_clip.utils.replace_linear(model, int8_linear_layer, include_modules=['c_fc', 'c_proj']).cuda()
    int8_model = int8_model.to(device)
    tokenizer = open_clip.get_tokenizer(model_name)
    print("====return quantize clip====")
    return int8_model, transform, tokenizer

This code is placed in /clip_benchmark/models/quantize_model.py
My run command is as follows：
clip_benchmark eval --dataset=cifar10 --task=zeroshot_classification --pretrained=/models/clip_model/DFN5B-CLIP-ViT-H-14-378/open_clip_pytorch_model.bin --model=ViT-H-14-378-quickgelu --output=quantize.json --batch_size=64 --/CLIP_benchmark/dataset --model_type=quantize

Detailed error records are as follows:

I want to explain what I'm going to do。
I want to keep the text model unchanged and only quantize the visual model of the open_clip model. I'm not sure if open_clip provides this functionality. Maybe I can achieve it through other methods. But after quantizing the visual model, how can I only load the quantized local weights for the visual model and load other weights for the text model? I'm very confused about this and hope to get your help!

I am experiencing the same issue on a fresh checkout. Any updates about what's going on here?
