Describe your issue

I have defined the method void predict_on_batch inside class PredictGPU

I have declared class PredictGPU in python code

and call method predict_on_batch

When i run app on debug mode, predict_on_batch method is called, but throw error when return.
How can anyone help me, please?

I have tested with inputs=None ==> It working
but when inputs not None then app throw error above despite of nothing in method

Thanks for the report, we'll fix this in the next version of Chaquopy.

Meanwhile, you can work around the problem by converting the NumPy array to a Java array manually, like this:

from java import jarray, jfloat
predict.predict_on_batch(jarray(jarray(jarray(jarray(jfloat))))(data), data_len[0])

This issue is fixed in Chaquopy 10.0.1. To upgrade, edit your app's top-level build.gradle file and change the version number of com.chaquo.python:gradle.
