TypeError: Invalid input type 'PdfDocument'

[Athe-kunal]

I took the convert_single.py file and ran the following code on Google colab after doing pip install marker-pdf

import argparse
import os

from marker.convert import convert_single_pdf
from marker.logger import configure_logging
from marker.models import load_all_models

from marker.output import save_markdown

model_lst = load_all_models()
langs = ["en"]
batch_multiplier = 2
fname = "/content/input/temp.pdf"
output = "output_dir"
os.makedirs(output,exist_ok=True)
full_text, images, out_meta = convert_single_pdf(str(fname), model_lst, max_pages=1,langs=langs, batch_multiplier=batch_multiplier)

fname = os.path.basename(fname)
subfolder_path = save_markdown(output, fname, full_text, images, out_meta)

I am getting the following error

TypeError: Invalid input type 'PdfDocument'

The full error trace is here

    raise TypeError(f"Invalid input type '{type(input_data).__name__}'")
TypeError: Invalid input type 'PdfDocument'

Also, I tried with the command line, and I got this error. How can I resolve it?

Run pip install -U marker-pdf. Should fix it

[tangxqa]

I encountered the same problem, but I have already taken action： pip install -U marker-pdf。 run: marker_single /Users/tangxqa/Downloads/Demystifying_the_Topologies_Behind_prompting_1706394504.pdf ./output --batch_multiplier 1 --max_pages 10 --langs Chinese

The code you're showing in the traceback is not from the latest version. Check if you have 0.2.9

[xzdong-2019]

marker-pdf (0.2.9) but i have the same issue on linux.
marker-pdf(0.2.8) is ok on windows.
