[YU JUNJIE]

I upload the alexnet.pdf and click start analyse ,it return an Error.
And I check the IDE it show this.

TypeError: Unsupported input type: <class 'tempfile._TemporaryFileWrapper'>

I copy it to the GPT4,it answered me :

The error is caused by the pdfminer.high_level.extract_pages() function expecting a file path (a string) or a file-like object as its argument, but it appears to be receiving a tempfile._TemporaryFileWrapper object instead.

To fix this issue, you should pass a proper file path or a file-like object to the extract_pages() function. You can make the following changes in your gpt_reader\bot\openai.py file:

1.If you are using a temporary file, make sure to call the name attribute to get the file path before passing it to the extract_pages() function:

temp_file_path = tempfile_object.name
for page_layout in extract_pages(temp_file_path):

2.Alternatively, if you want to pass a file-like object, you can open the temporary file in binary mode and pass it to the extract_pages() function:

with open(tempfile_object.name, "rb") as file_object:
for page_layout in extract_pages(file_object):

By ensuring that you are passing the correct file path or file-like object to the extract_pages() function, you should be able to avoid the TypeError raised in your script.
