Trying to use pdf2image on databricks, but its failing with "PDFInfoNotInstalledError: Unable to get page count. Is poppler installed and in PATH?"

I've installed pdf2image & poppler-utils by running the following in a cell:

%pip install pdf2image

%pip install poppler-utils

But still hitting this error.

Can anyone help with my next step please?

(Rather annoyingly, this question was asked before at this url https://forums.databricks.com/questions/62529/pdf-to-image-using-poppler.html which I can see in google search results, but the databricks community forum seems to have changed format. If anyone knows how to translate from the old forum urls to new that would also be appreciated!)

Thanks
