AttributeError: module 'tvm.auto_scheduler._ffi_api' has no attribute 'RandomModel'

[Promortyus]

Description

I encountered an AttributeError when running tools/run_pipeline.py in the T-MAC project. Even if I followed all the steps in the readme.md, it seems that tvm.auto_scheduler._ffi_api does not contain RandomModel, which causes the script to fail during execution.

Environment

• OS: Windows 11
• Python version: Python 3.9

Step to Reproduce

Run the following command:

python tools/run_pipeline.py -o "C:\Users\L\.cache\huggingface\hub\models--1bitLLM--bitnet_b1_58-3B"
-q int_n
