我在尝试复现论文中关于parallel各向同性（isotropic）对称性的实验时遇到了一些技术问题，想向您请教。
环境配置：
操作系统：Ubuntu 20.04.6 LTS
Python版本：3.8
已按照README配置好依赖
修改的参数：
在 main.py 中设置 cur_tradeoff = "Max:E-Min:nu"
在 config.ini 中设置 pcdtype = parallel（对应论文中的六边形isotropic对称性p31m）
报错信息：
当运行 python main.py 时，出现以下错误：
(metamaterial) smile-mint@LAPTOP-H2C5T9E5:/mnt/c/Users/9999/Desktop/GraduationProject/evo_cppn_material-main-back$ python main.py

观察：
我测试了其他几种对称性（如 完全各向异性nosym、四方对称性sym4 等），代码都能正常运行，唯独在设置为 parallel 且目标为弹性模量-泊松比（Max:E-Min:nu）组合时出现此错误。
请问这是否与parallel对称性下的特定边界条件处理或返回值结构有关？或者是我遗漏了某些针对isotropic对称性的特殊配置？
期待您的指导
