'UnstructuredPDFLoader' is not defined

[netingweb]

Hallo If I try to execute the tutorial either on colab or local I always get the following error NameError: name 'UnstructuredPDFLoader' is not defined even if I install all packages as shown on https://langchain.readthedocs.io/en/latest/modules/document_loaders/examples/unstructured_file.html

Hello! Can you paste in your error message to chat gpt and see what it says?

If it’s undefined then it can’t find that package and you might be referencing the wrong path

Unstructured is tough to get going for some users.

Just updated the code with another loader https://github.com/gkamradt/langchain-tutorials/blob/main/data_generation/Ask%20A%20Book%20Questions.ipynb
