Markitdown produces nothing?

[zhangguochun]

Hello, does anyone have the same issue or know why. I can't use markitdown to covert a pdf. it doesn't throw any exceptions either. It just outputs blank. Thank you for any clues.

from markitdown import MarkItDown
from langchain_ollama import ChatOllama
client = ChatOllama(model="llama3.2")
# md = MarkItDown(llm_client=client)
md = MarkItDown()
result = md.convert("test.pdf")
print(result.text_content)```

or tested it via command:
markitdown test.pdf
