似乎无法使用新的 GridDB Python 客户端查询时间序列容器？

Question

查询集合容器工作正常，但查询任何类型的时间序列容器——即使只是一个简单的 select *——都会导致分段错误。

这是我的 Dockerfile 的样子：

这里是 gdb 在运行 griddb 示例代码 sample2.py

时的输出

如果我查询收集容器，没有段错误。有什么想法吗？

Answer 1

查看docker文件，问题可能是因为同时安装了Python 3.6和Python 3.10。 Python 3.6 用于构建，但 Python 3.10 用于运行示例，如下所示：

您安装 Python 3.10：从源代码构建 python。然后你安装 pandas 和 Python 3.10.
您安装 Python 3.6：使用 yum。你没有安装 pandas 和 Python 3.6.
您安装Python客户端：系统使用python3.6构建Python客户端
你运行 sample2.py 与 Python 3.10.
