Unable to Process Images

[beerdedfellow]

Hello,

I am currently attempting to use tabula-py to process PDF files that contain an image. However, whenever I attempt to read the document with tabula.read_pdf, I get an error similar to the following:

(3.9.10/envs/alert_logic) jona5523@RXT-Macbook-Pro-2.local:/Users/jona5523/github/Alert-Logic-Billing git:(main*) $ ./app.py 
Got stderr: Sep 07, 2022 3:09:16 PM org.apache.pdfbox.contentstream.PDFStreamEngine operatorException
SEVERE: Cannot read JPEG2000 image: Java Advanced Imaging (JAI) Image I/O Tools are not installed

So to ensure that tabula-py was using a version of tabula-java that was compiled with these dependencies, I cloned the tabula-java repo and built the .jar manually:

jona5523@RXT-Macbook-Pro-2.local:/Users/jona5523/github/tabula-java git:(master) $ tail -15 pom.xml 

    <dependency>
        <groupId>com.github.jai-imageio</groupId>
        <artifactId>jai-imageio-jpeg2000</artifactId>
        <version>1.4.0</version>
    </dependency>

    <dependency>
        <groupId>org.apache.pdfbox</groupId>
        <artifactId>jbig2-imageio</artifactId>
        <version>3.0.4</version>
    </dependency>
</dependencies>

</project>

jona5523@RXT-Macbook-Pro-2.local:/Users/jona5523/github/tabula-java git:(master) $ mvn clean compile assembly:single

Then I moved this .jar in the path of the tabula-py site-packages:

jona5523@RXT-Macbook-Pro-2.local:/Users/jona5523/.pyenv/versions/3.9.10/envs/alert_logic/lib/python3.9/site-packages $ cp ~/github/tabula-java/target/tabula-1.0.6-SNAPSHOT-jar-with-dependencies.jar tabula/tabula-1.0.5-jar-with-dependencies.jar

jona5523@RXT-Macbook-Pro-2.local:/Users/jona5523/.pyenv/versions/alert_logic/lib/python3.9/site-packages/tabula $ grep -A1 "TABULA_JAVA_VERSION" io.py 
TABULA_JAVA_VERSION = "1.0.5"
JAR_NAME = "tabula-{}-jar-with-dependencies.jar".format(TABULA_JAVA_VERSION)
JAR_DIR = os.path.abspath(os.path.dirname(__file__))

I also attempted a manual download of 1.0.5 from github but got the same results:

jona5523@RXT-Macbook-Pro-2.local:/Users/jona5523/.pyenv/versions/alert_logic/lib/python3.9/site-packages/tabula $ wget https://github.com/tabulapdf/tabula-java/releases/download/v1.0.5/tabula-1.0.5-jar-with-dependencies.jar -qO tabula-1.0.5-jar-with-dependencies.jar

I am unsure why I am continuing to get this error even though I ensured that tabula-py is using a tabula-java JAR that was compiled with the proper dependencies. Appreciate any help you can provide!

On the same boat. Were you able to resolve it?

Hi @sonu-gupta. Do you get an exception, or just a warning? tabula-java Tables contained in images are not read by Tabula anyways, so an exception of that kind can be safely ignored.
