树初始化中出现Illegal instruction (core dumped)的问题

在步骤样本产出及树初始化中，
运行 python tree_init.py
出现Illegal instruction (core dumped)
请问这个情况应该怎么处理

Start by reproducing the failure with `python tree_init.py` during the sample-output and tree-initialization steps, then inspect the environment and execution context around the reported `Illegal instruction (core dumped)`. Done means the tree initialization completes without the crash, with a reproducible test or documented environment confirming the result.
