Error in PULPino toolchain installation

[amitops2103]

Hello,
I am working in a project in which we have to design a RISC-V core. So i was taking the reference of Zero-RISCY core.
So I compiled first https://github.com/pulp-platform/pulp-riscv-gnu-toolchain for general RV32 toolchain. But for Zero-RISCY core and

1. Count instruction cycles.
2. Analyze pipeline timing Run on Zero-RISCY simulator.
3. Study how C maps to instructions.
   I cloned the present repo and tried ./update-ips.py the script is in python2 and the wsl supports python3.

How can I compile pulpino toolchain for Zero-RISCY core completly and verify the above works.
