PDFInfoNotInstalledError: Unable to get page count. Is poppler installed and in PATH?

[hherpa]

I tried to run your google collab notepad: "06.private-gpt4all-qa-pdf.ipynb". I didn't edit your code, but just started the cells step by step. In this section of the code:

images = convert_from_path("ms-financial-statement.pdf", dpi=88)
len(images)

I had this kind of error:

---------------------------------------------------------------------------

During handling of the above exception, another exception occurred:
