No model hoster is available! Please check your network connection to one of the following model hosts:
HuggingFace (https://huggingface.co),
ModelScope (https://modelscope.cn),
AIStudio (https://aistudio.baidu.com), or
BOS (https://paddle-model-ecology.bj.bcebos.com).
Otherwise, only local models can be used.
Creating model: ('PP-LCNet_x1_0_doc_ori', None)
Using official model (PP-LCNet_x1_0_doc_ori), the model files will be automatically downloaded and saved in C:\Users\Admin.paddlex\official_models.
No available model hosting platforms detected. Please check your network connection.

程序已经启动了好几遍了
因为单位的运行环境是不能联网的，所有还得请专家帮忙看一下
