Crash after the error "type numpy.ndarray doesn't define __round__ method"

[limerick1718]

Hi, I use the default settings to test the APK org.woheller69.spritpreise_18.apk.zip

The script I used is:

python3 parallel_exec.py --list_device AVDName --appium_ports APPIUMNAME --android_ports ANDROIDPORT --path APPDIR --timer 70 --platform_version 8.1 --algo SAC --timesteps 5000 --trials_per_app 3

The test performs well at the beginning. However, the test speed rush up and suddenly output the error

type numpy.ndarray doesn't define __round__ method
OK: killing emulator, bye bye

Then the emulator restarts again.

Would you please kindly check what's wrong with it?

Thank you very much!
