Pyserini library not working in google colab

[bhavikchandana]

while import pyserini library, I am getting this error

JavaException: JVM exception occurred: io/anserini/eval/Qrels has been compiled by a more recent version of the Java Runtime (class file version 65.0), this version of the Java Runtime only recognizes class file versions up to 55.0 java.lang.UnsupportedClassVersionError
Can you tell how to solve this problem??

Got the solution. Just go back to older version of pyserini :). Pls look into this...

You need to upgrade your JVM to JDK 21. Per the README:

Yeah thanks the upgrading is not happening on colab from my side... Still downgrading pyserini version worked
