Could not execute pdfimages to calculate DPI

[tadamhicks]

I am getting this error when I run pypdfocr

WARNING: Could not execute pdfimages to calculate DPI (try installing xpdf or poppler?), so defaulting to 300dpi

I have pdfimages (and poppler) installed. Not sure why I would be getting this error.

More info. I get this while running on a Linux VM. pdfimages is in my $PATH. I do not get this on my mac. In another Linux VM it finds pdfimages, but I get:
