Permission Error with PDF loader

[realglyph123]

I was testing OnlinePDFLoader yesterday iirc and it was working fine. Today I tried experimenting and I keep getting this error

PermissionError: [Errno 13] Permission denied: 'C:\\Users\\REALGL~1\\AppData\\Local\\Temp\\tmp3chr08y0

it may be occurring because the tempfile.NamedTemporaryFile() in pdf.py is still open when the PDF partitioning function is trying to access it

I have the same problem when running PDF loader of local environment (no problem when running on Colab). Do you have any solution yet?

Go to the pdf.py and replace the function using the code below located on the BasePDFLoader class. Note that my current version of langchain is .137

    file_path: str
    web_path: Optional[str] = None
    temp_file: Optional[tempfile.NamedTemporaryFile] = None

    def __init__(self, file_path: str):
        """Initialize with file path."""
        self.file_path = file_path
        if "~" in self.file_path:
            self.file_path = os.path.expanduser(self.file_path)

        if not os.path.isfile(self.file_path) and self._is_valid_url(self.file_path):
            r = requests.get(self.file_path)

            if r.status_code != 200:
                raise ValueError(
                    "Check the url of your file; returned status code %s"
                    % r.status_code
                )

            self.web_path = self.file_path
            self.temp_file = tempfile.NamedTemporaryFile(delete=False)
            self.temp_file.write(r.content)
            self.temp_file.close()
            self.file_path = self.temp_file.name
        elif not os.path.isfile(self.file_path):
            raise ValueError("File path %s is not a valid file or url" % self.file_path)

    def __del__(self) -> None:
        if self.temp_file is not None:
            self.temp_file.close()
            os.unlink(self.temp_file.name)

I still have this issue with 0.0.1.81 windows 11 bitdefender AV
issue discussed here: https://stackoverflow.com/questions/76200691/issue-with-loading-online-pdf-in-python-notebook-using-langchain-pypdfloader
Hope there might be a cross platform solution.
