normalize_tool_choice 是 xgrammar 库的一个公共函数，用于规范化工具调用（tool-calling）的参数。现在的问题是，只要不涉及工具调用，是可以工作的。一旦涉及工具调用，就会报错。但是升级的话，涉及@15287246311同学提到的这个问题，依赖冲突太多了。

你好，请问你解决了吗？方便看一下你的pip list结果吗

ERROR: Cannot install apache-tvm-ffi==0.1.9 and xgrammar==0.2.6 because these package versions have conflicting dependencies.

The conflict is caused by:
The user requested apache-tvm-ffi==0.1.9
xgrammar 0.2.6 depends on apache-tvm-ffi>=0.1.10

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip to attempt to solve the dependency conflict
