Error dealing with pdf files

[soham-aiplanet]

This is my code

def process_google_drive_documents(folder_url: str, service_account_cred: dict):
    source = ab.get_source(
        "source-google-drive",
        config={
            "folder_url": folder_url,
            "credentials": {
                "auth_type": "Service",
                "service_account_info": json.dumps(service_account_cred),
            },
            "streams": [
                {
                    "name": "pdf_loader_stream",
                    "globs": ["**"],
                    "format": {"filetype": "unstructured"},
                }
            ],
        },
    )

    source.check()
    source.select_all_streams()
    read_result = source.read()

And here's the error -

Any idea how to resolve this ?

Hi @soham-aiplanet !
I see the error message you encountered, and I believe it has to do with a missing resource in the Natural Language Toolkit (NLTK) library.
The error appears because the punkt tokenizer is needed to parse text in the document, but it’s not currently available in your environment. To resolve this, please install punkt by running:

import nltk
nltk.download('punkt')

After installing it, try running the code again, and the error should be resolved. Please let me know if this works or if you run into any other issues.
