dashscope/qwen:LLM Provider NOT provided

[cotol7]

When I use dashscope/qwen model, it prompts that the model provider has not provided it. But doesn't the official website show that the model is available?

litellm.BadRequestError: LLM Provider NOT provided. Pass in the LLM provider you are trying to call. You passed model=dashscope/qwen-max
 Pass model as E.g. For 'Huggingface' inference endpoints pass in `completion(model='huggingface/starcoder',..)` Learn more: https://docs.litellm.ai/docs/providers [sleep 10 seconds]
