I am trying to extract tables from this pdf link using camelot, however, when a try this follow code:

import camelot

file = 'relacao_medicamentos_rename_2020.pdf'

tables = camelot.read_pdf(file)
tables.export('relacao_medicamentos_rename_2020.csv', f='csv', compress=False)

Simple nothing happens. This is very strange 'cause when I try the same code but with this pdf link works very welll.
