我正在尝试运行一个 python 2.7 脚本，该脚本使用并行 python（版本 1.6.1）在 Ubuntu Voyager（Ubuntu 12.04 衍生版本）系统上执行使用 numpy 数组（numpy 版本 1.6.1）的函数。它给了我以下错误消息（实际上，它仍然更长，我猜重复了 12 次）：

从其他线程（例如在 Parallel Python 中导入 NumPy）我已经看到这可能是 pp 和 numpy 的通信问题，所以我尝试了这些：

  • 更新 pp 和 numpy
  • 重新安装 numpy（我正在使用 anaconda 包）
  • 直接从 shell 运行代码（而不是从 spyder）
  • 将多数组（否则导入就好）直接提交给工作的工人（我确定我有正确的语法......）

但无济于事。你有什么其他的建议？除了 erm 之外还有一个简单的解决方法吗？我的同事使用相同操作系统的更新版本，但使用相同的 python 设置，似乎没有这个问题，但由于时间是一个问题，更新我的系统或劫持他较慢的计算机都不是最好的选择。

如有必要，请随时询问更多详细信息并提前感谢您。
