在 Jupyter 上运行的 SageMath 出现内存限制错误

我在 juypter 上运行 SageMath 时遇到以下错误。该代码适用于较小的数据集，但不适用于较大的数据集。它说我必须分配更多内存，我尝试更改 juypter 的配置文件中的缓冲区大小，并得到相同的错误。任何建议将不胜感激。

有同样的问题。看看以下是否有帮助。

import sage.libs.ecl
sage.libs.ecl.ecl_eval("(ext:set-limit 'ext:heap-size 0)")

您可以更改的内存限制可以在手册中找到。

https://ecl.common-lisp.dev/static/files/manual/current-manual/Memory-Management.html#tab_003amem_002dlimits

如有错误欢迎指正，因为我也在学习Sage的过程中。
