Describe your issue

My Python version is 3.10. Downgrading to 3.8 is not an option.

I am currently using the interpolation feature within the opencv2-python package to resample time-series data signals. However, when attempting to run this Python code in an Android environment using Chaquopy, I encountered the issue that there isn’t a wheel file available at https://chaquo.com/pypi-13.1/opencv-python/ for this package. As a result, we currently have only a partial setup that excludes resampling for data types requiring interpolation. To correctly resample signals regardless of data type, having an opencv2-python wheel file compatible with Python 3.10 would be highly beneficial.

resample_signal code

import cv2 
...
    def resample_signal(self, ecg, method="INTER_CUBIC"):
        rate_resample = self.sampling_rate_org / self.sampling_rate
        if rate_resample % 1 == 0:
...
            ecg = ecg[****]
#         else:
#             ecg = cv2.resize(
#                 ecg,
#                 dsize=(****),
#                 interpolation=getattr(cv2, method),
#             )
        return ecg
