OSError: [Errno 22] Invalid argument

[double-evil]

Hi,I meet some trouble when I tried using this toolkit.
When I extracted molecule information from PDFs,It shows [Erron 22] and there are some mistakes about file path.
ERROR reported as follows:
Traceback (most recent call last): File "D:\coding practice\pythonproject\OpenChemIE\test.py", line 6, in <module> figure_results = model.extract_reactions_from_figures_in_pdf(pdf_path) File "c:\windows\system32\openchemie\openchemie\interface.py", line 450, in extract_reactions_from_figures_in_pdf figures = self.extract_figures_from_pdf(pdf, num_pages=num_pages, output_bbox=True) File "c:\windows\system32\openchemie\openchemie\interface.py", line 203, in extract_figures_from_pdf return table_ext.extract_all_tables_and_figures(pages, self.pdfparser, content='figures') File "c:\windows\system32\openchemie\openchemie\interface.py", line 74, in pdfparser self.init_pdfparser() File "c:\windows\system32\openchemie\openchemie\interface.py", line 85, in init_pdfparser self._pdfparser = lp.AutoLayoutModel(config_path, model_path=ckpt_path, device=self.device.type) File "D:\WorkSoftware\Anaconda\envs\openchemie\lib\site-packages\layoutparser\models\auto_layoutmodel.py", line 64, in AutoLayoutModel return ALL_AVAILABLE_BACKENDS[backend_name]( File "D:\WorkSoftware\Anaconda\envs\openchemie\lib\site-packages\layoutparser\models\effdet\layoutmodel.py", line 138, in __init__ self._initialize_model(config_path, model_path, label_map, extra_config) File "D:\WorkSoftware\Anaconda\envs\openchemie\lib\site-packages\layoutparser\models\effdet\layoutmodel.py", line 164, in _initialize_model model_path = PathManager.get_local_path(model_path) File "D:\WorkSoftware\Anaconda\envs\openchemie\lib\site-packages\iopath\common\file_io.py", line 1251, in get_local_path bret = handler._get_local_path(path, force=force, **kwargs) File "D:\WorkSoftware\Anaconda\envs\openchemie\lib\site-packages\layoutparser\models\effdet\catalog.py", line 64, in _get_local_path return PathManager.get_local_path(model_url, **kwargs) File "D:\WorkSoftware\Anaconda\envs\openchemie\lib\site-packages\iopath\common\file_io.py", line 1251, in get_local_path bret = handler._get_local_path(path, force=force, **kwargs) File "D:\WorkSoftware\Anaconda\envs\openchemie\lib\site-packages\iopath\common\file_io.py", line 835, in _get_local_path with file_lock(cached): File "D:\WorkSoftware\Anaconda\envs\openchemie\lib\site-packages\portalocker\utils.py", line 316, in __enter__ return self.acquire() File "D:\WorkSoftware\Anaconda\envs\openchemie\lib\site-packages\portalocker\utils.py", line 270, in acquire fh = self._get_fh() File "D:\WorkSoftware\Anaconda\envs\openchemie\lib\site-packages\portalocker\utils.py", line 329, in _get_fh open( # noqa: SIM115 OSError: [Errno 22] Invalid argument: 'C:\\Users\\andyjiang/.torch/iopath_cache\\s/gxy11xkkiwnpgog\\publaynet-tf_efficientdet_d1.pth.tar?dl=1.lock'
Mistakes happen when it operates to utils.py in portalocker module.
Here are some infomation about my operating env:
python 3.9.21
portalock 3.1.1
iopath 0.1.10

I am looking forward to your reply and I will appretiate it if you could reply as fast as possible！Thank you！

Okay, here's how to fix openchemie/interface.py on Windows for the FileNotFoundError caused by publaynet-tf_efficientdet_d1.pth.tar.

Problem: The model isn't found locally, and automatic download fails.

Solution (Windows):

1. Download the model:
   Go to https://www.dropbox.com/s/gxy11xkkiwnpgog/publaynet-tf_efficientdet_d1.pth.tar?dl=1 in your browser. Download the file publaynet-tf_efficientdet_d1.pth.tar.

2. Place the file:
   Create a new folder named models inside your OpenChemIE project root: E:\06_git\oder_info2\1016\OpenChemIE\models.
   Move the downloaded publaynet-tf_efficientdet_d1.pth.tar file into this new models folder.

3. Modify openchemie/interface.py:
   Open E:\06_git\oder_info2\1016\OpenChemIE\openchemie\interface.py.
   Find the init_pdfparser method. Change it to:
   # -- coding: utf-8 --
   # ... (other imports)
   import os
   # ...

   class OpenChemIE:
       # ...
   
       @lru_cache(maxsize=None)
       def init_pdfparser(self, ckpt_path=None):
           config_path = "lp://efficientdet/PubLayNet/tf_efficientdet_d1"
           
           if ckpt_path is None:
               current_file_dir = os.path.dirname(os.path.abspath(__file__))
               project_root = os.path.dirname(current_file_dir) 
               
               local_model_path = os.path.join(project_root, "models", "publaynet-tf_efficientdet_d1.pth.tar")
               
               if not os.path.exists(local_model_path):
                   raise FileNotFoundError(f"LayoutParser model not found: {local_model_path}. "
                                           "Please download it from the project's documentation and place it in the 'models' directory.")
                   
               ckpt_path = local_model_path
           
           self._pdfparser = lp.AutoLayoutModel(config_path, model_path=ckpt_path, device=self.device.type)
   

4. Save the file.

Now, when you run run_example.py, it will load the model from your local models folder.
