进入你的虚拟环境后执行：

问题二：updown_concat_xgb.model缺失

0.26.2版本中使用DeepDOC切片时会出现ragflow/rag/res/deepdoc/updown_concat_xgb.model": No such file or directory，原因是0.26.x版本已经不需要updown_concat_xgb.model，但代码没有更新

在ragflow/deepdoc/parser/pdf_parser.py中改为None即可

try: model_dir = os.path.join(get_project_base_directory(), "rag/res/deepdoc") # self.updown_cnt_mdl.load_model(os.path.join(model_dir, "updown_concat_xgb.model")) self.updown_cnt_mdl = None except Exception: model_dir = snapshot_download(repo_id="InfiniFlow/text_concat_xgb_v1.0", local_dir=os.path.join(get_project_base_directory(), "rag/res/deepdoc")) # self.updown_cnt_mdl.load_model(os.path.join(model_dir, "updown_concat_xgb.model")) self.updown_cnt_mdl = None
