我知道这个问题已经被问过多次，但是有了其他线程的答案，我无法解决我的问题。我在命令行中运行 python 脚本python3 CTGAN_noscale.py --database_name CTGAN_noshift并收到以下错误（使用故障处理程序）：

Fatal Python error: Segmentation fault

似乎问题出在 optuna 上。奇怪的是，在另一台服务器上一切正常，在更改服务器后它像这样崩溃了

更新

我发现当我不使用 docker 容器或使用没有 GPU 的 docker 容器时，问题不会发生。

我通过重建一个新图像并从该图像派生一个容器来解决了这个问题。在这个容器中，错误不再出现。
