python环境需要在3.8以上
安装:pip install nougat-ocr
模型默认下载地址:/home/****/.cache/torch/hub/nougat-0.1.0-small
环境安装好之后默认使用cpu
UserWarning: CUDA initialization: The NVIDIA driver on your system is too old (found version 11080). Please update your GPU driver by downloading and installing a new version from the URL: http://www.nvidia.com/Download/index.aspx Alternatively, go to: https://pytorch.org to install a PyTorch version that has been compiled with your version of the CUDA driver. (Triggered internally at ../c10/cuda/CUDAFunctions.cpp:108.)
return torch._C._cuda_getDeviceCount() > 0
WARNING:root:No GPU found. Conversion on CPU is very slow.
如果需要使用GPU,则需要重新安装和自己cuda版本对应的torch等,我这边是cuda11.8
conda install pytorch torchvision torchaudio pytorch-cuda=11.8 -c pytorch -c nvidia
环境配置好之后即可进行PDF识别
在output目录下会生成.mmd格式的文件
vscode中使用如下插件可以查看mmd格式中的内容,文字可直接复制
