"bash scripts/download_pretrained.sh" is failed

Hello, my friend.  I am in step 2 of "getting started/general". When I execute the instructions for downloading pre-training files and datasets, a 409 error occurs. The relevant environment has already been configured. Can you tell me the solution?
当我执行预训练文件下载和数据集下载的指令时，都会发生409的错误，前面的相关环境已经配好了，你能告诉我解决方法吗？
