USD Mac上运行失败

Python crashed. FATAL ERROR: Failed axiom: ' Py_IsInitialized() 

原因分析：

使用Conda python,而不是直接使用本机的的Python环境编译的USD。

解决方案：

在使用Conda python编译USD的时候加入额外的参数

python build_scripts/build_usd.py /opt/local/USD --build-args USD,"-DPXR_PY_UNDEFINED_DYNAMIC_LOOKUP=ON"

参考文档：

Conda distributed Pythons are statically linked as a way to reduce unexpected system and installation coupling, but Python isn’t, to my knowledge, built in such a way that an external build system can robustly discover whether you are targeting a static or dynamically linked Python so we are forced to deal with it manually.
