在PDF中提取化学相关信息,报失败,各位大佬是怎么解决的这个问题

[Plp15079287565]

#运行脚本如下
import torch
from openchemie import OpenChemIE

model = OpenChemIE(device=torch.device('cpu')) # change to cuda for gpu
pdf_path = r'E:\OpenChemIE\example\acs.joc.2c00749.pdf'
figure_results = model.extract_reactions_from_figures_in_pdf(pdf_path)
text_results = model.extract_reactions_from_text_in_pdf(pdf_path)

报错如下
