CVE_2018_5383_Invalid_Curve_Attack_PoC.py execution error

[DKnight-hub]

I used two nexus 5 version phones to execute the CVE_2018_5383_Invalid_Curve_Attack_PoC.py file, but the following error occurred when this file was executed on the ubuntu system:

[] Using adb device: 04250993437df21a (AOSP on HammerHead)

Can you know what went wrong?
