@davidfor - would it be better to use the libtessaract library with the python wrapper rather than platform specific executables.

That error suggests that I missed something when doing the Python 3 work. Can you post the details of the error message? That gives a line number to look at. And tell us which version of calibre you are using. |

Are you running the release version, 1.5.10? There was another release earlier in the year that could use OCR for PDFs. If you are using that, I won't be able to help. Have you tried converting the PDF to another format? If that doesn't work, I don't think this plugin will work. It uses some of the function that a conversion does to get the text from the PDF and then search that. If it does convert, I suspect I will only be able to help with a copy of the book. If it is legal to do so, you can post it here. Or, if it is somewhere I can legally download it, please post the link. Otherwise, you can upload it somewhere and send a PM with a link to down it. |

it may be that none of the books HAVE ISBN's embedded.
This PI is mostly for those that do not have other sources for metadata (and have been issued a ISBN (none of my owners manuals have ISBN's, but they are PDF ) Why not search the Internet for the book, then see if Calibre (or MR) has a Metadata source PI for that site? |

Do you only have PDFs? Or is it failing for epubs or other formats? Did you try the conversion I suggested? This will help tell if it is calibre or something external blocking it. And, has this ever worked? Or is this the first time you have tried the plugin? |
