In fact, I spent about 3 hours configuring the environment, and these environment issues always appeared only after the LLM tokens had been consumed. First, RMBG-2.0 reported an error; I installed the corresponding dependencies as prompted and then reran it. Then another error occurred. I tried downgrading numpy, downgrading transformers, downgrading various things, and finally was informed that the older CUDA version cannot be used with the RTX5090; I could only continue by disabling the 5090 and relying on the CPU for computation.
If you could provide a detailed environment setup tutorial, that would be great!
