How to extract symvers from kernel?

Question

linux

I need to extract symvers from the kernel in order to assemble the module. I found a script for this https://github.com/glandium/extract-symvers (but as I understand it is written in python 2). Installed unbootimg , unpacked my kernel (boot.img), received 3 files including zImage. I found out the address (xs how to call 0xffffffc001374000) with this command adb shell dmesg | grep "\.init". And when I write the command

python extract-symvers.py -B 0xffffffc001374000 zImage > Module.symvers

, I get

Traceback (most recent call last):
  File "extract-symvers.py", line 139, in <module>
    main()
  File "extract-symvers.py", line 135, in main
    for s, crc, t in kernel.symbols():
  File "extract-symvers.py", line 102, in symbols
    for t, s in symsearch.items():
AttributeError: 'NoneType' object has no attribute 'items'

Versions of python Python 2.7.15+ and Python 3.6.8. Do I understand correctly, do I need to redo the code for Python 3?
