Extracting Text from scanned pdf

I was not able to convert a pdf to an image. Eventhough the poppler is in path the below issue is occuring.

Input:

from pdf2image import convert_from_path
images = convert_from_path('abc.pdf')
for image in images:
    image.save('abc.png', 'PNG')

Output

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