服务器上paddleOCR的bug记录

bug1:

问了同事发现他的窗口可以运行，我的不行，应该是修改了什么配置文件。我看网上说是libcudnn.so和libcublas.so的问题。

看来服务器上面的screnn还有不同的性质啊！

export命令设置的环境变量在当前会话中是暂时的，因为它们只在当前会话中有效，并且在会话结束后将被清除。当你打开一个新的终端会话或重新登录时，之前使用export命令设置的环境变量将不再存在。--gpt 3.5

ref只需要一句

export LD_LIBRARY_PATH=xxx/lib:$LD_LIBRARY_PATH

就可以了！LD_LIBRARY_PATH是你的xxx/anaconda3/envs/env_name/lib 路径

不过后面还有一个小bug，

[2023/12/07 11:33:32] ppocr ERROR: error in layout recovery image:./doc/doc_jc/Musculo2013.pdf, err msg: [Errno 2] No such file or directory: 'output/structure/Musculo2013/[0, 211, 963, 1462]_1.jpg'

这个是因为没有保存图貌似。额，这个是自己写的，不算bug应该。

后面table居然出现了数组越界的错误，十分难受：

Traceback (most recent call last):
  File "ppstructure/predict_system.py", line 336, in 
    main(args)
  File "ppstructure/predict_system.py", line 274, in main

    res, table_time_dict = self.table_system(
  File "/home/llm/Projects/PaddleOCR/ppstructure/table/predict_table.py", line 86, in __call__
    structure_res, elapse = self._structure(copy.deepcopy(img))
  File "/home/llm/Projects/PaddleOCR/ppstructure/table/predict_table.py", line 109, in _structure
    structure_res, elapse = self.table_structurer(copy.deepcopy(img))
  File "/home/llm/Projects/PaddleOCR/ppstructure/table/predict_structure.py", line 147, in __call__
    post_result = self.postprocess_op(preds, [shape_list])
  File "/home/llm/Projects/PaddleOCR/ppocr/postprocess/table_postprocess.py", line 56, in __call__
    result = self.decode(structure_probs, bbox_preds, shape_list)
  File "/home/llm/Projects/PaddleOCR/ppocr/postprocess/table_postprocess.py", line 87, in decode
    text = self.character[char_idx]
IndexError: list index out of range

不知道为什么。之前都没有这个问题。。。。
